Hard drives fail. Laptops get stolen. Ransomware encrypts everything on your primary drive and anything plugged into it. The only answer to all three problems is a backup copy stored somewhere else — and for most people, that means an external hard drive.
The market is full of drives that look identical at $49 and $99. The price difference is almost never about raw capacity. It’s about platters, firmware, warranty terms, and whether the manufacturer will help you recover data when the drive dies (and it will die, eventually). These five picks are the ones we’d actually trust.
If you haven’t set up a full backup strategy yet, read our Complete PC Backup Guide first — it covers the 3-2-1 rule and explains which combination of local and cloud backup gives you real protection, not just peace of mind.
Portable vs. Desktop: Which Type Do You Need?
External hard drives split into two distinct categories, and the right choice depends on how you plan to use the drive.
Portable Hard Drives
Portable drives are bus-powered — they draw power through the USB cable, so there’s no AC adapter. They’re compact enough to throw in a laptop bag. Most connect via USB-C (with a USB-A adapter included) and hold 1–5TB. The tradeoff is that bus power limits the drive size: portable HDDs use 2.5-inch platters, which max out around 5TB before the power draw exceeds what USB can reliably supply. If you need more than 5TB in a portable form factor, you’re looking at an external SSD — see our Best SSDs 2026 guide for those picks.
Desktop Hard Drives
Desktop drives have their own AC power brick and use 3.5-inch platters. They can hold up to 22TB in consumer versions, and they’re designed to stay on your desk. Transfer speeds are higher (150–180 MB/s versus 120–140 MB/s for portable), and the larger platter size means lower cost per terabyte. If you’re backing up a family’s worth of photos, a home media server, or running Time Machine continuously, a desktop drive is the right call.
What Actually Matters When Buying a Backup Drive
Capacity and price are the specs most people compare. Neither predicts how long the drive will actually last.
- Warranty length and data recovery coverage. A 2-year warranty is table stakes; 3 years is better. Some drives (LaCie, certain Seagate tiers) include Rescue Data Recovery Services — a professional data recovery service that will pull your files from a dead drive, which ordinarily costs $300–$1,500 out of pocket.
- Brand lineage and failure rate data. Backblaze publishes real-world drive failure statistics every year using data from tens of thousands of drives in their storage pods. WD and Seagate consumer drives consistently appear in the low-failure-rate tiers. Avoid white-label drives, and be skeptical of anything that’s only sold on Amazon under a brand you’ve never heard of.
- Interface: USB-C vs. USB-A. If your laptop has USB-C ports, get a drive with a USB-C connector. The cable doesn’t affect transfer speed (USB 3.2 Gen 1 caps at 5 Gbps either way) but it does affect cable durability over years of plugging and unplugging.
- Hardware encryption. If you’re backing up a work laptop or anything with sensitive files, a drive with AES 256-bit hardware encryption (WD My Passport, LaCie) adds protection if the drive is stolen. Software encryption through BitLocker or VeraCrypt is a free alternative.
- Bundled software. Most backup drives come with proprietary backup software. You don’t have to use it — Windows File History, Windows Backup, and macOS Time Machine all work with any drive. But some bundles (Seagate’s Mylio Photos and Adobe CC Photography inclusions) have real value worth factoring into the price.
Quick Comparison Table
| Drive | Type | Capacity | Interface | Warranty | ~Price |
|---|---|---|---|---|---|
| WD My Passport Ultra 5TB | Portable | 1–5TB | USB-C 3.2 Gen 1 | 3 years | ~$100 |
| Seagate Expansion Portable 2TB | Portable | 1–5TB | USB-A 3.0 | 2 years | ~$50 |
| WD My Book Desktop 8TB | Desktop | 4–22TB | USB-A 3.0 | 3 years | ~$150 |
| LaCie Rugged Mini HDD 4TB | Portable/Rugged | 1–5TB | USB-C 3.2 Gen 1 | 3 yr + Rescue | ~$120 |
| Seagate Backup Plus Hub 8TB | Desktop | 4–14TB | USB-A 3.0 | 3 yr + Rescue | ~$160 |
1. WD My Passport Ultra 5TB — Best Overall
WD My Passport Ultra 5TB
~$100
The WD My Passport Ultra earns its position here on three points: WD’s track record (consistently among the lowest-failure-rate portable drives in Backblaze’s annual reports), a genuine 3-year warranty that doesn’t require registration gymnastics, and hardware AES 256-bit encryption with password protection built into the firmware. No software install required to enable it.
Transfer speeds hit 120–130 MB/s reading and 110–120 MB/s writing in real-world use, which makes backing up 100GB around 14 minutes — fast enough that you’ll actually run backups regularly rather than putting them off. The drive comes with a USB-C cable and a USB-C to USB-A adapter, so it works with both new and older machines without hunting for adapters.
The included WD Backup software and WD Discovery app are optional. Most users are better served by Windows File History or macOS Time Machine, both of which work fine with this drive out of the box. The 5TB version is the sweet spot — it gives you room for multiple full backup snapshots without costing $140+ for the top-end capacity.
Pros
- 3-year warranty, no registration required
- Hardware encryption included
- USB-C native with USB-A adapter in the box
- WD’s reliability track record
- Compact, pocket-sized
Cons
- Bundled WD backup software is mediocre
- No data recovery service included
- Slightly higher price than bare-bones alternatives
2. Seagate Expansion Portable 2TB — Best Budget
Seagate Expansion Portable 2TB
~$50
If you want a reliable backup drive and don’t want to think about it, the Seagate Expansion Portable is the answer. There’s no software to install, no account to create, no firmware to update. You plug it into a USB port and it shows up as a drive. That’s it.
The Expansion has been Seagate’s mass-market portable drive for years, which means it’s been through more real-world testing than most alternatives. Read speeds sit around 115–120 MB/s — not the fastest on this list, but adequate for backup use. The drive comes formatted exFAT, so it works with both Windows and Mac without reformatting.
The tradeoff is a 2-year warranty (one year shorter than the WD My Passport), no hardware encryption, and a USB-A connector only — you’ll need a USB-C to USB-A adapter if your laptop only has USB-C ports. For around $50, those are acceptable compromises. This is the drive to buy if your budget is firm or you want a second copy of your backup stored offsite.
Pros
- Lowest price on this list
- Completely plug-and-play
- Works on Windows and Mac without reformatting
- Reliable Seagate internals
Cons
- 2-year warranty, not 3
- No hardware encryption
- USB-A only — needs adapter for USB-C laptops
3. WD My Book Desktop 8TB — Best High-Capacity Backup
WD My Book Desktop 8TB
~$150
The WD My Book is the desktop backup drive with the longest track record in its class. The 8TB version costs around $150 — that’s under $19 per terabyte, which is substantially cheaper than any portable drive at this capacity. For a stationary backup drive that sits next to your router or desktop tower, the larger form factor and AC power brick are non-issues.
Because it uses a 3.5-inch platter with AC power, the My Book runs faster than portable drives: 150–180 MB/s sustained reads, which means a 1TB backup completes in around 90–110 minutes rather than two-plus hours. The drive includes hardware encryption and an automatic backup button on the front panel for quick incremental syncs without opening software.
One important note: the My Book is ideal for continuous Time Machine or Windows File History use. If you want to leave it connected and let macOS or Windows handle scheduled backups automatically, this is the drive for that workflow. Disconnect it after backups complete if ransomware protection matters to you — any connected drive is encrypted alongside your primary disk in a ransomware attack.
Pros
- Lowest cost-per-terabyte on this list
- Fast 3.5-inch platters
- 3-year warranty
- Hardware encryption built in
- One-touch backup button
Cons
- Requires AC outlet — not portable
- USB-A only
- No data recovery service included
4. LaCie Rugged Mini HDD 4TB — Best for Travel and Tough Conditions
LaCie Rugged Mini HDD 4TB
~$120
If the drive is going in a camera bag, a field kit, or a bag that regularly gets thrown on the floor, the LaCie Rugged Mini is the only mechanical drive worth considering. The orange rubber bumper provides genuine drop resistance (tested to 1.2 meters), and IP54 rating means it handles rain, dust on job sites, and the occasional coffee splash without concern.
What separates LaCie from just buying a portable drive and hoping for the best is the Rescue Data Recovery Services included in the 3-year warranty. If the drive dies within three years, LaCie will send a prepaid box, recover the data in their lab, and send it back on a new drive. That service normally costs $300–$1,500 out of pocket. For photographers, videographers, and anyone keeping irreplaceable work on external drives, that coverage changes the math significantly.
Transfer speeds are in line with other 2.5-inch drives: 120–130 MB/s reads. The drive ships formatted exFAT and comes with both a USB-C cable and a USB-C to USB-A cable. The only real downside is price — the 4TB LaCie Rugged costs about $20–$30 more than the WD My Passport at the same capacity. You’re paying for the rubber shell and the Rescue coverage.
Pros
- Rescue Data Recovery Services included (huge value)
- Drop and splash resistant
- USB-C native
- 3-year warranty
- Both USB-C and USB-A cables in the box
Cons
- Premium price vs. non-rugged alternatives
- Bulkier than standard portable drives
- No hardware encryption
5. Seagate Backup Plus Hub 8TB — Best for Multi-Device Households
Seagate Backup Plus Hub 8TB
~$160
The Seagate Backup Plus Hub earns its place on this list by solving a specific household problem: you need a desktop backup drive, but you also want a hub to charge phones and tablets without chasing power outlets. The Hub has two USB-A ports on the front that deliver 5W charging — enough for phones, smartwatches, and tablets. It’s a small thing that makes the drive genuinely useful as a desk fixture rather than something you only interact with during backups.
Like the LaCie Rugged, the Hub includes Rescue Data Recovery Services within the 3-year warranty — professional recovery at no charge if the drive fails during that window. Seagate also bundles a 4-month Mylio Photos subscription (cloud-based photo management) and a 2-month Adobe Creative Cloud Photography plan, which together have real value if you shoot photos and don’t have a photo management workflow yet.
The Hub uses a 3.5-inch platter with 150–175 MB/s reads. At 8TB for around $160, it’s priced nearly identically to the WD My Book at the same capacity. The deciding factor: if you want the Hub’s front USB charging ports and Rescue coverage, choose the Hub. If you want hardware encryption, choose the My Book.
Pros
- Rescue Data Recovery included
- Front USB charging ports are genuinely useful
- 3-year warranty
- Fast desktop-class speeds
- Bundled software has real value
Cons
- No hardware encryption
- USB-A only
- Requires AC outlet
- Seagate’s backup software is optional but gets pushed hard
Which One Should You Buy?
- Best overall for most people: The WD My Passport Ultra 5TB is the one to buy if you want a single, reliable portable backup drive with hardware encryption and a 3-year warranty. It costs $100 and covers everything a personal laptop backup needs.
- Best if your budget is under $60: The Seagate Expansion Portable 2TB is the no-frills choice that gets the job done. No encryption, 2-year warranty, USB-A only — but it’s from a reliable manufacturer and will work fine for years.
- Best for home backup of large libraries: The WD My Book 8TB is the pick if you’re running Time Machine or Windows File History continuously, backing up multiple family devices, or storing a large media collection. The cost-per-terabyte is hard to beat.
- Best if the drive travels in a bag: The LaCie Rugged Mini 4TB is the only mechanical drive on this list with real drop and water protection. The Rescue Data Recovery coverage makes the price premium worth it for photographers and field workers.
- Best for a household with multiple devices: The Seagate Backup Plus Hub 8TB adds Rescue coverage and front USB charging ports to a solid desktop drive. Buy it if you want the Hub features; choose the My Book if you want hardware encryption.

How long do external hard drives last?
Most external hard drives last 3 to 5 years under normal use, with many running longer. Backblaze’s annual failure rate reports consistently show annualized failure rates under 2% for years 1 through 3, rising noticeably after year 4. Variables that shorten lifespan: frequent travel in a bag (vibration and drops), running hot due to poor ventilation, and leaving portable drives spinning continuously. Plan to replace backup drives every 4 years regardless of apparent health, and always verify that backups are readable before the old drive goes.
Are external hard drives good for long-term backup?
External hard drives are well-suited for medium-term backup — 3 to 5 years of active use with proper handling. For archival storage beyond 10 years, periodic refreshes (copying data to a new drive every 3–4 years) or optical M-DISC media are the recommended approach. For most people’s backup needs — protection against drive failure, accidental deletion, and ransomware — an external HDD following the 3-2-1 rule (three copies, two media types, one offsite) is entirely adequate. Cloud backup handles the offsite component with minimal effort.
Should I use an external HDD or external SSD for backup?
For a stationary backup drive that lives on your desk, a hard drive gives you significantly more storage per dollar: a 5TB portable HDD is around $100, while a 5TB portable SSD runs about $350. For a backup drive you carry in a bag, an SSD is worth the premium — no moving parts means no damage in a drop. If maximum reliability is the goal and the drive won’t travel, a desktop HDD with a 3-year warranty is the practical choice. Check our Best SSDs 2026 guide if you want the portable SSD picks.
How much external storage do I need for backup?
Size your backup drive at 1.5 to 2 times the amount of data you’re protecting. If your laptop has a 512GB SSD that’s 60% full (≈300GB of data), a 1TB drive holds that backup with some overhead, but a 2TB drive gives you room for multiple snapshots over time. Households with large photo or video libraries should start at 4TB. The price difference between 2TB and 4TB portable drives is typically $25–$30 — buy the larger size to avoid running short in year two.
What backup software works with external hard drives?
Windows 11 includes File History (continuous file versioning) and Backup and Restore (full system images), both of which work with any external drive without installation. macOS includes Time Machine, which is tightly integrated and works best with drives formatted APFS or HFS+. WD and Seagate both bundle proprietary backup apps, but most users are better served by the OS built-ins. For more control over scheduling and versioning on Windows, Macrium Reflect Free is the community standard — it’s free, actively maintained, and trusted by IT professionals.
Is it safe to leave an external hard drive plugged in all the time?
Desktop drives with AC adapters (WD My Book, Seagate Backup Plus Hub) are designed for continuous operation and it is safe to leave them connected. Portable bus-powered drives are not designed for always-on use — sustained spinning wears them faster than intended. For always-on backup, use a desktop drive. For portable drives, plug in, let the backup run, and unplug. Security note: ransomware encrypts connected drives alongside your primary disk. Disconnecting a backup drive after each session provides a layer of protection that always-on drives can’t match.
