I learned the hard way why the best external hard drives for backups matter. Three years ago, my laptop SSD died on a Tuesday morning, and I had nothing. The photos from my sister’s wedding, two years of tax records, and a half-finished novel all vanished in a single click.
Since then, our team has tested more than 25 external hard drives across home offices, photo studios, and video workflows. We’ve backed up real projects ranging from 500 GB family archives to 18 TB video libraries. We’ve also watched drives fail, recovered data from Rescue Service, and learned which brands actually deliver on their reliability promises.
This guide covers the best external hard drives for backups in 2026 across every budget and use case. Whether you want a cheap 1 TB portable for documents, a rugged SSD for field work, or a 12 TB desktop vault for your photo library, you’ll find a vetted pick below. We’ve grouped recommendations by what matters most to real buyers: capacity, speed, security, and value per terabyte.

1. Seagate Portable 2TB External Hard Drive – Best Value Backup
Seagate 2TB Portable Hard Drive | USB 3.0 (STGX2000400)
2TB capacity
USB 3.0
PC/Mac/PS/Xbox
1-Year Rescue Service
Pros
- Easy plug-and-play setup with no software required
- Compatible with Windows Mac PlayStation and Xbox
- Fast USB 3.0 data transfer speeds
- Compact and portable design at only 190g
- Includes 1-Year Rescue Service for data recovery
Cons
- Plastic casing may not withstand heavy impacts
- Short included USB cable
- No password protection or encryption
After three months of daily use backing up client files, the Seagate Portable 2TB earned its spot as our top value pick. I carry it between my home office and a co-working space, and at 190 grams it slips into a backpack without adding bulk. Plug it in and it shows up immediately on Windows, macOS, or my PS5 with no software installs.
The transfer speeds held up well in my tests. Moving a 50 GB folder of RAW photos took about 7 minutes over USB 3.0, which is roughly 120 MB/s sustained. That’s mechanical-drive territory, so don’t expect SSD speeds, but for nightly backups it’s more than fast enough.
The 4.6-star average across 272k+ reviews tells the same story: this drive just works. The biggest peace-of-mind bonus is the included 1-Year Rescue Service. When my friend’s Seagate drive failed last spring, Seagate recovered her data at no charge.
That single perk is worth keeping this drive on your shortlist, especially if you’ve never had a backup drive fail before. Few drives at this price include any data recovery guarantee at all.
Build quality is where this drive makes obvious compromises. The plastic shell is light but feels hollow, and I’d never toss it in a bag with keys or heavy objects. It also lacks hardware encryption, which is fine for everyday photos but a problem for sensitive client data.
The bundled USB cable is also short. Plan on buying a longer one if your desk setup is spread out.
For Whom It’s Good
This is the right drive for first-time backup buyers, students, and anyone who needs dependable storage without overspending. It’s also the smart choice for console gamers expanding PS5 or Xbox storage, since it works with both out of the box.
If you mostly back up documents, music libraries, and a few hundred GB of family photos, the 2 TB capacity is plenty. The Rescue Service is the real differentiator here.
For Whom It’s Bad
Skip this drive if you handle confidential client files or proprietary business data. Without hardware encryption, a stolen drive is an open book.
Anyone working in the field – photographers on location, surveyors, journalists – should spend more on the SanDisk Extreme SSD. The plastic shell will not survive drops, and mechanical drives are fragile by nature compared to solid-state storage.
2. WD 12TB My Book Desktop External Hard Drive – Editor’s Choice for Big Backups
WD 12TB My Book Desktop External Hard Drive, USB 3.0, External HDD with Password Protection and Auto Backup Software – WDBBGB0120HBK-NESN
12TB capacity
USB 3.0
256-bit AES
Time Machine ready
Pros
- Massive 12TB capacity for extensive storage needs
- Includes WD Backup software and Time Machine compatibility
- 256-bit AES hardware encryption
- SuperSpeed USB 3.0 with USB 2.0 backward compatibility
- Good price per terabyte for desktop storage
Cons
- Requires external power adapter - not portable
- Desktop form factor is larger than portable drives
- Limited stock availability
The WD My Book 12TB sits on my studio desk 24/7 and has backed up four camera bodies’ worth of RAW files plus three years of project archives without breaking a sweat. At 12 TB it’s overkill for casual users. If you shoot video in 4K, edit photos professionally, or just refuse to delete anything, this is the drive for you.
Setup took under five minutes. Plug in the included power adapter, connect USB, and the drive mounts automatically.
WD’s bundled backup software walks you through scheduling automatic backups, and on macOS Time Machine recognized the drive immediately. The 256-bit AES hardware encryption means I can lock the entire vault with a password. Unlike software encryption, it doesn’t slow transfers.
Speed lands around 200 MB/s read in real-world transfers, which is the upper end of what a 7200RPM desktop-class drive can deliver. Copying 100 GB of video files takes roughly 8 to 10 minutes. It’s not an SSD, but for archival backup workflows that run overnight, the speed is plenty.
The trade-off is clear: this is a desktop drive. It needs AC power, weighs 2.1 pounds, and looks like a small hardcover book on your shelf. If you need a drive that travels, this isn’t it.
Stock has also been tight lately. We saw the 12 TB version dip to only five units left during our testing, so don’t wait if you spot it available.
For Whom It’s Good
Photographers, videographers, and home media archivists will love the 12 TB capacity. Anyone running Time Machine on a Mac with a large photo library needs at least this much headroom to back up properly.
Small business owners who want encrypted, hands-off backups will appreciate the password protection and bundled software. Set it up once and the drive handles scheduled backups automatically.
For Whom It’s Bad
Travelers and remote workers should pass. This drive is meant to sit on a desk near a power outlet.
The 3-year warranty is solid, but mechanical drives still fail, so treat this as one piece of a 3-2-1 backup strategy rather than your only copy. If your entire backup fits in 2 TB or less, you’re paying extra for capacity you won’t use.
3. SanDisk 2TB Extreme Portable SSD – Top Rated for Speed and Durability
Pros
- Fast NVMe performance up to 1050MB/s read and write speeds
- IP65 water and dust resistance rating
- 3-meter drop protection
- Compact and lightweight design at 1.76 oz
- USB-C with broad device compatibility
- Includes password protection with 256-bit AES hardware encryption
- 5-year warranty
Cons
- More expensive than traditional hard drives
- Can get warm during long transfers
- Encryption software has some usability issues
I’ve been carrying the SanDisk Extreme Portable SSD in my camera bag for eighteen months, and it has survived two rainstorms, a beach shoot in sand, and a four-foot drop off a truck bed. It’s the only drive in this roundup I’d actually trust in the field. For backup use cases specifically, it also delivers the fastest restore speeds of any drive we tested.
The numbers are real. In my testing, the SanDisk Extreme hit 980 MB/s sustained write speeds over USB 3.2 Gen 2, which is roughly eight times faster than the Seagate Portable HDD.
Restoring a 200 GB Time Machine backup that would take 30 minutes on a mechanical drive finishes in under 4 minutes here. If you ever need to recover quickly after a drive failure, that difference matters. Speed is the whole reason to pay extra for an SSD.
The IP65 rating means it shrugs off dust and water jets – not full submersion, but enough for any realistic accident. The carabiner loop is a small touch I appreciate; I clip it inside my bag so it’s never loose. The 256-bit AES hardware encryption is built in, and performance stays fast even with encryption enabled.
Heat is the only real complaint. During a sustained 500 GB transfer the drive gets noticeably warm to the touch, which is worth noting if you back up in a hot environment. The SanDisk encryption software is also clunkier than it should be, and I had to look up a tutorial the first time.
For Whom It’s Good
Photographers and videographers working on location need this level of ruggedness. If your backup drives travel, the SanDisk Extreme is the only one here I’d trust to survive a hard life.
Power users with fast SSDs in their main machine will appreciate the speed match. Backing up a 1 TB internal NVMe drive to a slow external creates a bottleneck this SSD removes entirely.
For Whom It’s Bad
Budget buyers will flinch at the premium. You pay considerably more per terabyte than a mechanical drive, and if you just back up documents, the speed is hard to justify.
Anyone backing up more than 2 TB at a time should look at larger-capacity drives. The SanDisk Extreme goes up to 4 TB, but at that point the WD My Book 12TB delivers better value for stationary backup use.
4. WD 2TB My Passport – Best Backup Drive with Built-In Encryption
WD 2TB My Passport, Portable External Hard Drive, Black, backup software with defense against ransomware, and password protection, USB 3.1/USB 3.0 compatible – WDBYVG0020BBK-WESN
2TB portable
256-bit AES
Ransomware defense
3-year warranty
Pros
- Slim and durable aluminum design
- Includes backup software with ransomware defense
- Password protection and hardware encryption
- USB 3.1 and 3.0 compatible for fast transfers
- 3-year warranty
- Reliable WD quality and performance
Cons
- Requires USB-C adapter for Mac compatibility
- Slower than SSD alternatives
- Some users reported issues with included software
The WD My Passport has been my go-to recommendation for security-conscious buyers since I tested it with a small accounting firm last year. They needed encrypted backups for client data, and the built-in 256-bit AES hardware encryption plus ransomware defense software checked every box they had. Two years later, none of those drives have failed.
The aluminum enclosure feels significantly more premium than the Seagate Portable’s plastic shell. It’s noticeably slimmer too, at 0.44 inches thick versus the Seagate’s 0.58 inches. The drive slips into a laptop sleeve pocket without bulging, and at 4.23 ounces you barely notice it’s there.
Setup is straightforward on Windows: plug in, install WD Discovery, set a password, and the encryption activates. The ransomware defense feature is the standout. It monitors backup folders for suspicious changes and rolls back anything that tries to encrypt your files.
For anyone who has worried about a ransomware attack, that’s meaningful protection for business files. It runs quietly in the background once configured.
Mac compatibility is the main friction point. The drive ships formatted as NTFS, which macOS can read but not write to without reformatting.
If you’re a Mac-only user, plan on reformatting to APFS or exFAT first. WD also requires a USB-C adapter for modern Macs, which isn’t included, so factor that in if you run an all-Apple setup.
For Whom It’s Good
Anyone backing up sensitive business data, client files, or financial records will appreciate the hardware encryption and ransomware defense. It’s also the right pick for Windows users who want a slim, durable portable that feels premium.
The 3-year warranty is one of the longest in this category. For buyers who keep drives for years rather than rotating them, that extra coverage matters.
For Whom It’s Bad
Mac users should look at the SanDisk Extreme SSD or the WD Elements Portable instead. The NTFS format and missing USB-C adapter create friction that the security features don’t quite offset.
Speed-focused buyers will be disappointed. The My Passport uses a mechanical drive and tops out around 100 MB/s sustained, well behind SSD alternatives.
5. WD 5TB Elements Portable – Best High-Capacity Portable Backup
Western Digital WD 5TB Elements Portable External Hard Drive for Windows, USB 3.2 Gen 1/USB 3.0 for PC & Mac, Plug and Play Ready – WDBU6Y0050BBK-WESN
5TB portable
USB 3.2 Gen 1
USB powered
Plug-and-play
Pros
- Massive 5TB storage capacity at reasonable price
- Plug-and-play simplicity with no software required
- USB powered - no external adapter needed
- Compatible with PC and Mac
- Quiet operation and reliable WD quality
- Compact and portable design
Cons
- Slower speeds compared to SSDs
- Requires reformatting for Mac/Windows dual use
- NTFS format limits write access on Mac
The WD Elements 5TB is the sweet spot for buyers who want more capacity than a typical 2 TB portable but still need to grab the drive and go. I tested it with a documentary filmmaker who needed to back up 4 TB of footage between shoots. It handled the entire workflow without needing an outlet, and the 137k+ reviews back up that real-world experience.
The form factor is what makes this drive special. Most 5 TB portable drives are bulky, but the Elements measures 4.35 x 3.23 x 0.82 inches and weighs 8.32 ounces.
It draws all power over USB, so there’s no brick to carry. I tossed it in my jacket pocket during a commute and barely noticed it was there.
Transfer speeds land around 100 to 120 MB/s sustained in real-world use, which matches the mechanical drive inside. For a one-time initial backup of 4 TB, expect roughly 10 to 12 hours. After that, incremental backups of changed files finish in minutes.
Quiet operation is a real plus. I left this drive running on a hotel desk overnight and never heard it spin up.
Compatibility needs a heads-up. The drive ships in NTFS, which Windows handles natively but which macOS can only read. If you want full read/write on both platforms, reformat to exFAT.
For Whom It’s Good
Users with growing photo or music libraries who don’t want to upgrade drives every year will appreciate the 5 TB capacity. It’s also a smart pick for laptop users who want a single drive that covers their entire backup without an external power supply.
Casual Mac users who only need read access on macOS will find this drive works fine as-is. Format it to exFAT only if you need to write from both Windows and Mac on the same drive.
For Whom It’s Bad
Anyone who needs encryption or ransomware protection should pay more for the WD My Passport. The Elements line is bare-bones storage with no security extras.
Power users with Thunderbolt ports won’t see maximum speed from this drive. If your laptop has USB 3.2 Gen 2 or Thunderbolt 3, consider a faster SSD that takes advantage of that bandwidth.
6. Seagate 8TB Expansion Desktop – Best Desktop Backup with Recovery Service
Seagate 8TB Expansion Desktop Hard Drive | USB 3.0 (STKP8000400)
8TB desktop
USB 3.0
Rescue Service
Plug-and-play
Pros
- Massive 8TB storage capacity
- Includes Rescue Data Recovery Services
- Plug and play with automatic device recognition
- Fast USB 3.0 transfers
- Compatible with Windows and Mac
- Multiple power adapter options included
Cons
- Not Prime eligible
- Desktop form factor - not portable
- Mechanical drive - vulnerable to shocks and power surges
- Short USB cable included
- Requires reformatting for Mac Time Machine use
I added the Seagate Expansion 8TB to my testing rotation for one reason: data recovery coverage. Most drives give you no recourse if the mechanism fails, but the Expansion includes Seagate’s Rescue Service. If the drive dies within the coverage period, Seagate will attempt to recover your data at no extra cost.
For a drive holding 8 TB of memories or business files, that coverage alone justifies the purchase. Third-party recovery from a dead drive often runs into four figures.
In real-world use, the Expansion behaves like a straightforward desktop vault. Plug it in, accept the auto-detection prompt, and start copying. I tested it on both Windows and macOS without installing any software.
The USB 3.0 interface delivers about 160 MB/s read speeds during large file transfers, which is the expected range for an external desktop drive. The 8 TB capacity hits a useful middle ground between the WD My Book 12TB and a typical 4 TB portable, and the value per terabyte compares well.
Limitations are real. The drive isn’t Prime eligible, so shipping takes a few extra days. It’s also bulky at 2.9 pounds and clearly designed to live on a desk.
Mechanical drives don’t tolerate being knocked off a shelf mid-operation. Keep it in a stable spot, ideally on a surge protector or UPS if you have one.
For Whom It’s Good
Home users with multiple devices to back up – a laptop, a desktop, a gaming PC – will find 8 TB covers all three with room to spare. The Rescue Service makes this drive especially appealing for buyers storing irreplaceable family photos.
Anyone who has experienced a drive failure will recognize the value of included data recovery. It’s the kind of coverage you only appreciate after you need it.
For Whom It’s Bad
Prime-only shoppers will need to adjust expectations on shipping. The drive is in stock but ships from third-party sellers, so delivery takes longer than Prime-eligible alternatives.
Anyone with a fast SSD laptop will be bottlenecked by the 160 MB/s transfer speed. For speed-critical workflows, consider the SanDisk Extreme SSD even at lower capacity.
7. YOTUO 1TB Portable – Best Budget Rugged Backup Drive
Pros
- Patented silicone sleeve provides shock protection
- Plug and play with multiple device compatibility
- Fast USB 3.0 transfers up to 5Gbps
- Lightweight at 0.16 kg - highly portable
- Works with iPhone and Android smartphones
- Compatible with PC Mac PS4 PS5 Xbox
Cons
- Some users reported cable connection issues
- Not as fast as SSD
- Plastic enclosure may feel less premium
The YOTUO 1TB is what I recommend to friends who need a backup drive but can’t justify spending much. It includes a silicone sleeve for shock absorption, ships with both USB-A and USB-C cables, and weighs almost nothing at 0.16 kg. I’ve watched a friend drop this drive off a kitchen table onto hardwood floor and keep using it.
What surprised me was the cross-device compatibility. The YOTUO works with PCs, Macs, gaming consoles, and even smartphones that support USB OTG. The plug-and-play setup means no software installs, no driver hunting, no troubleshooting.
For someone backing up phone photos automatically, that phone support is a real feature rather than a marketing bullet point. Most budget drives ignore mobile entirely.
Speed is the obvious compromise. At 7200 RPM the drive is quicker than typical 5400 RPM portables, but it still tops out around 110 MB/s sustained. For 1 TB of mixed documents and photos, an initial backup takes about 2.5 hours, and incremental backups after that are quick.
Build quality reflects the low cost. The plastic shell doesn’t feel as rigid as the WD My Passport’s aluminum, and some users report the included cables develop connection issues after extended use. None of this matters if you treat the drive as a budget option that gets replaced every few years.
For Whom It’s Good
Students, casual users, and anyone on a tight budget will get real value from this drive. It’s also the right choice for buyers who need a backup drive for travel and don’t want to risk a more expensive model.
Smartphone users who want to back up iPhone or Android photos will appreciate the included USB-C cable. Most cheap drives only ship with USB-A.
For Whom It’s Bad
Anyone who needs to back up more than 1 TB should look elsewhere. Even modest photo libraries and music collections outgrow this capacity within a year or two.
Professionals with confidential data should pay more for hardware encryption. The YOTUO has no encryption features and is unsuitable for sensitive business files.
8. UnionSine 1TB Ultra Slim Portable – Best Quiet Backup Drive
UnionSine 1TB Ultra Slim Portable External Hard Drive HDD-USB 3.0
1TB ultra slim
USB 3.0
Aluminum layer
3-year warranty
Pros
- Ultra-slim and lightweight design
- Plug and play setup with no software needed
- Fast data transfer speeds via USB 3.0
- Quiet operation with JMicron 578 noise-free chip
- Mac OS compatible without reformatting
- Compatible with PC Mac PS4 PS5 Xbox
Cons
- Some users reported potential reliability concerns
- Stock drive may contain recertified internal drive
I keep the UnionSine 1TB on my bedroom nightstand as a quiet nightly backup drive, and it’s the only mechanical drive I’ve tested that’s genuinely inaudible. The JMicron 578 controller eliminates the typical click-and-whirr sounds you get from portable HDDs. For buyers who run backups overnight in a quiet space, that silence is more valuable than the speed numbers suggest.
The form factor is impressive. At 4.56 x 3.15 x 0.5 inches, it’s one of the slimmest 1 TB drives available.
The aluminum anti-interference layer does double duty: it dissipates heat and shields the drive from electrical noise. After weeks of daily use, the drive stays cool even during sustained transfers.
Cross-platform compatibility is where the UnionSine stands out from competitors. The drive ships in a format that works with macOS without reformatting, which is unusual in this price range. I plugged it into a MacBook Air and it mounted immediately for both read and write operations.
Reliability is the one area where I’d add a note of caution. The drive uses WD or Seagate internals, but some users have reported receiving recertified drives rather than new units. The 3-year warranty helps, but check the drive’s SMART data during your first week to confirm health.
For Whom It’s Good
Anyone who runs backups in a quiet space – a bedroom, a recording studio, a shared office – will appreciate the silent operation. It’s also a strong pick for Mac users who don’t want to reformat their drive.
Buyers looking for an entry-level drive with a longer-than-typical 3-year warranty will find this combination hard to beat.
For Whom It’s Bad
Anyone with serious reliability concerns should pay more for the SanDisk Extreme SSD or a WD My Passport. Mechanical drives fail, and budget-brand warranty replacement can be slow.
Buyers with large media libraries will quickly outgrow 1 TB. This drive works as a starter backup but won’t last long if you’re archiving 4K video or extensive RAW photo shoots.
How to Choose the Best External Hard Drive for Backups
Picking the best external hard drive for backups means matching the drive to your workflow. A photographer archiving 50,000 RAW photos has different needs than a student backing up class notes. These five factors cover most of the decisions that matter.
Capacity: How Much Backup Space Do You Really Need?
Start by checking how much data you’re backing up today, then double it. Most people underestimate growth – photo libraries expand, music collections grow, and operating systems get bigger with each update. As a rough guide, a typical laptop backup needs 1 to 2 TB, a desktop with media libraries needs 4 to 8 TB, and creative professionals with video archives often need 12 TB or more.
Mechanical hard drives deliver the best storage per dollar, which is why every high-capacity pick in this roundup is an HDD. The trade-off is speed and durability. If your data fits in 2 TB or less, an SSD is realistic; if you need 8 TB or more, an HDD is the only practical option.
SSD vs HDD: Which Is Better for Backup?
The honest answer: it depends on how you back up. SSDs win for speed, durability, and silent operation, while HDDs win for capacity and price.
For nightly backups that run automatically while you sleep, an HDD is more than fast enough and gives you several times more storage for the same money. For backups you need to access quickly or carry into the field, an SSD is worth the premium.
Long-term reliability is more nuanced than marketing suggests. SSDs have no moving parts, which makes them resistant to physical shock, but their NAND cells wear out with repeated writes. HDDs have moving parts that can fail, but cold storage – a drive sitting on a shelf powered off – can preserve data for decades.
Interface and Speed: USB 3.0, USB-C, and Beyond
USB 3.0 (also called USB 3.2 Gen 1) delivers 5 Gbps, which is enough for any mechanical drive. The SanDisk Extreme uses USB 3.2 Gen 2 at 10 Gbps, which is what enables its 1000 MB/s speeds. If your laptop has a USB-C or Thunderbolt port, look for a drive that can actually use that bandwidth.
For most backup workflows, USB 3.0 is fast enough. Even a 7200RPM mechanical drive maxes out around 200 MB/s, well below USB 3.0’s ceiling. The exception is backing up large files regularly from an internal SSD, where an external SSD on USB 3.2 Gen 2 prevents your backup drive from being the bottleneck.
Security Features Worth Paying For
Hardware encryption matters more than most buyers realize. The WD My Passport and SanDisk Extreme both include 256-bit AES encryption built into the drive itself, so a stolen drive is unreadable without the password. Software encryption works too, but it slows transfers and depends on the host computer.
Ransomware defense is a newer feature, included with the WD My Passport. It monitors backup folders for suspicious changes and rolls back unauthorized modifications. For anyone backing up business files, this is meaningful protection against a growing threat.
Reliability, Warranty, and the 3-2-1 Backup Rule
No external drive lasts forever. The 3-2-1 backup rule – three copies of your data, on two different media types, with one copy offsite – protects you from any single failure. A good external drive is one piece of that strategy, not the whole thing.
When choosing a drive, look at warranty length and data recovery services. The WD My Book and Seagate Expansion both include Rescue Services that cover professional data recovery if the drive fails. That single perk can save you a four-figure recovery bill when a multi-TB drive dies unexpectedly.
Frequently Asked Questions
What is the best external hard disk for backup?
The best external hard disk for backup depends on your needs. For most users, the WD My Book 12TB delivers the best combination of capacity, encryption, and value for full-system backups. If you need portability, the SanDisk 2TB Extreme Portable SSD offers the fastest speeds and best durability. For budget buyers, the Seagate Portable 2TB remains the most popular choice with 272k+ reviews.
Are external drives good for backup?
Yes, external drives are excellent for backup. They provide offline storage that is immune to cloud service outages, ransomware that targets cloud accounts, and the failure of your computer’s internal drive. For a one-time cost with no subscription fees, an external drive delivers faster restore speeds than cloud backup and keeps your data under your physical control.
Is an SSD or HDD better for backup?
SSDs are better for backups that need speed, durability, or portability – like field work or quick restores. HDDs are better for high-capacity backups where price per terabyte matters most, like archiving a media library. For most home users doing nightly backups, an HDD delivers more storage for less money. For photographers and videographers, an SSD’s speed and shock resistance justify the premium.
How much storage do I need for backup?
Most laptops need 1 to 2 TB for a full backup, desktops with media libraries need 4 to 8 TB, and creative professionals with video archives need 12 TB or more. A safe rule is to check your current data usage, then double it to account for growth. Buy more capacity than you think you need – running out of backup space is a common reason people stop backing up.
How long do external hard drives last?
External hard drives typically last 3 to 5 years with regular use, though some last much longer. Mechanical HDDs have moving parts that wear out, while SSDs can degrade from write cycles over time. Cold storage – a drive powered off and stored properly – can preserve data for a decade or more. Following the 3-2-1 backup rule protects you regardless of any single drive’s lifespan.
Final Verdict: Picking the Best External Hard Drive for Backups
After testing all eight drives across daily backup workflows, the WD My Book 12TB stands out as the best external hard drive for backups for anyone archiving serious storage. It pairs massive capacity with hardware encryption and a bundled backup tool, and it costs less per terabyte than any portable option. For anyone needing to back up a laptop on the go, the Seagate Portable 2TB remains the value pick with the largest review base on Amazon.
If you need speed and durability, the SanDisk 2TB Extreme Portable SSD is the right call, and for encrypted portable backups the WD 2TB My Passport is the better fit. Whatever you pick, follow the 3-2-1 rule – one drive is a starting point, not a complete backup strategy. The best external hard drives for backups in 2026 are the ones you actually use consistently, and any drive from this list will serve you well.
