⚠ Market realityHard drives got a lot more expensive in 2026. On March 31, World Backup Day, a 22TB Seagate Expansion desktop drive sold for $389.99 at Best Buy — about $17.68 per terabyte. In the first days of October the 24TB version is about $690 on Amazon, roughly $29 per terabyte. That's around 60% more per terabyte in six months. The cause is the same AI data-center build-out that blew up RAM and SSD prices: Seagate told investors in July that most of its high-capacity drive output is already spoken for into 2028. Every price below is marked * — an October-2026 snapshot that's still moving, so check before you buy.
A spinning hard drive is still the cheapest way to keep a second copy of everything. Even at 2026 prices, a 16TB desktop drive costs about what a 2TB portable SSD does. That's why this guide exists alongside Issue 02 on external SSDs. The SSD is for speed and for carrying around. The hard drive is for bulk: the family photo library, the video archive, the full-system backup that runs every night.
I do data recovery in Clearwater, FL, so I see these drives at the end of their lives, not on the store shelf. That changes how I rate them. A drive earns points for a long warranty, for being plain and easy to recover from, and for living somewhere it won't get knocked over. It loses points for short warranties, for hiding which drive is inside, and for being sold as the only place your files will ever live. Ratings run a deliberately honest 3.0 to 4.5.
Before you buy · How these drives actually fail
What the failure data really says.
The best public numbers come from Backblaze, a cloud-backup company that publishes failure stats for every drive in its data centers. In its Q2 2026 report, covering 354,415 drives, the annualized failure rate was 1.73%. That means about 1.7 out of every 100 drives die in a given year. Backblaze called it the highest quarterly rate in quite a while. The lifetime rate across all its drives is 1.41%. The worst models that quarter were drives seven to eight-and-a-half years old.
In August, two economists published a peer-reviewed IEEE study that re-ran twelve years of that Backblaze data, more than 443,000 drives, and compared drives of the same age, size, and temperature. Their result: HGST drives failed at about 41% of Seagate's rate, WD at about 52%, and Toshiba at about 107%. Two things in that study matter more for you than the brand ranking. First, every extra degree Celsius of drive temperature raised failure rates about 2.1%. Here in Florida, a backup drive stacked on a router in a closet with no air flow is not a small detail. Second, Toshiba's failure rate jumped sharply once its drives passed five years in service.
Now the honest caveat: these are enterprise data-center drives, not the drives inside a $130 portable. The researchers say so themselves, and the Q2 2026 report actually had three Seagate models with zero failures. Treat brand reliability as a tiebreaker, not the whole decision. What kills consumer external drives in real homes is mostly simpler: drops, heat, power problems, and age.
SMR vs. CMR, in plain English
Hard drives write data in tracks, like the grooves on a record. CMR (conventional magnetic recording) keeps the tracks side by side. SMR (shingled magnetic recording) overlaps them like roof shingles to fit more data on each platter. The catch with SMR is that rewriting one track means rewriting its neighbors too. On a big, long copy, an SMR drive can slow to a crawl once its internal cache fills up.
For a backup drive, that's mostly fine. Backups are big sequential writes that you start and walk away from. Where SMR becomes a real problem is in a NAS or RAID array, where a slow rebuild can take days or fail outright. That's why Issue 08 on NAS units says to use CMR drives only. And here's what the box won't tell you: as far as anyone has been able to work out, nearly every 2.5-inch portable hard drive at 2TB and above is SMR. Manufacturers often don't say which one you're getting. Even Tom's Hardware notes that WD doesn't disclose it on its external drives.
Portable drives die from drops
Inside every hard drive, the read/write heads float a tiny fraction of a millimeter above platters spinning thousands of times a minute. If a running portable drive gets knocked off a desk, or yanked by its cable, those heads can hit the platter. That turns a working drive into a clicking one, and it's a clean-room job from there. Portables are the most exposed because they get carried, set on laps, and run off a single USB cable. The rules: eject before you unplug, never move a drive while it's spinning, and don't keep the only copy of anything on a drive that travels.
About shucking
"Shucking" means buying a desktop external drive and cracking the case open to use the bare drive inside a PC or NAS, because the external version is sometimes cheaper than the same drive sold bare. It works, but go in clear-eyed. Opening the case usually voids the warranty. Which exact drive is inside isn't published and changes over time. Some larger WD drives also use a power-disable feature that keeps them from spinning up in older PCs until you cover one pin or use an adapter. And you can't shuck most WD portables at all: the USB port is built into the drive's own circuit board, with no standard SATA connector to pull out. If you're building a NAS, buying proper CMR NAS drives is the safer route.
⚠ Field noteThe fake-drive problem got worse with the shortage. In May, a buyer who paid $20 for a "4TB" external drive on Temu opened it up and found a microSD card reader hot-glued inside a plastic shell. If the price looks too good, it is. Buy name brands from Amazon itself or a major retailer, not from no-name marketplace sellers. If a new drive's capacity seems off, a free tool like H2testw will tell you whether it can really hold what it claims.
Section A · Grab-and-go portables
The drive that travels — or lives in a laptop bag.
Portable drives are 2.5-inch hard drives powered by the USB cable, with no power brick. They're convenient, and they're the kind I see dead most often, because they get dropped. Buy one for moving files around or as a second copy of a laptop. If it's for the family archive, buy a desktop drive from Section B.
Pick 01 · Best portable
WD My Passport (1–6TB, USB 3.0)
4.0 / 5·DX·12A
Form factor2.5" bus-powered
Capacities1–6TB
Warranty3 years
RecordingNot disclosed (likely SMR)
Typical price~$215* (5TB)
This is the portable I'd hand most people. It's small, it runs on one cable, it goes up to 6TB, and it carries a 3-year limited warranty, the longest of any drive in this guide. In the first days of October the 4TB was about $181, the 5TB about $215, and the 6TB about $240. The 5TB and 6TB work out to roughly $40–43 per terabyte, which is as cheap as portable storage gets right now.
It ships with WD's backup software and password protection with hardware encryption. The WD Elements Portable is the same idea without the extras, but on the day I checked it actually cost a little more at 4TB and 5TB. So the My Passport is the better buy right now. What keeps the My Passport at a 4 is what every 2.5-inch drive shares: big copies slow down once the drive's cache fills, and it's fragile if it falls while it's running.
⚠ Field noteIf you set a password, write it down somewhere safe. The encryption on these drives is handled by the drive's own USB circuit board. If you lock the drive and forget the password, nobody can get the files back for you. If that board fails, recovery is harder than on a plain drive, because the data has to be decrypted along with the board. For a simple backup drive that stays at home, I'd leave the password off and keep the drive somewhere safe instead.
Strong points
3-year warranty, the longest here
Up to 6TB in a pocket-sized drive
Single cable, no power brick
Among the lowest cost per TB for a portable
Backup software included
Real-world drawbacks
Slows down on long, sustained copies (2.5" SMR)
Drop-sensitive while spinning
Hardware encryption complicates recovery
Can't be shucked (USB is built into the drive's board)
That orange rubber bumper isn't just looks. LaCie rates the Rugged Mini for drops, crush, and rain, and it includes a Rescue data recovery plan. If a drive is going to live in a work truck, a camera bag, or on a boat, this is the one I'd want there. Around Tampa Bay, that covers a lot of people.
Just be clear about what you're paying for. Inside is an ordinary 2.5-inch hard drive. LaCie is owned by Seagate. At about $249 for 4TB it costs roughly $62 per terabyte, about 50% more than the My Passport. Drop ratings like this are generally tested with the drive switched off. A bumper softens a fall, but it can't stop the heads hitting the platter if the drive is spinning when it lands. It's also an older USB 3.0 design, so it's no faster than the cheaper drives. That's why it gets a 3.5.
Strong points
Real protection from bumps, crush, and rain
Rescue data recovery plan included
2-year warranty
Easy to spot in a bag
Real-world drawbacks
~$62/TB, a steep premium per terabyte
Ordinary 2.5" drive inside, same drop physics while spinning
At the time of writing, this is the #1 best-selling external hard drive on Amazon, and it's probably the drive you already have in a drawer. It works: plug it in and it shows up, no software needed. I'm including it because it's the default choice, and I want to explain why I'd steer most people elsewhere.
Two reasons. First, the warranty is just 1 year, a third of the My Passport's. Second, at about $130 for 2TB it costs around $65 per terabyte. That's the worst value in this guide, and in 2026 it's getting close to small-SSD territory. A 5TB My Passport costs about $85 more and holds two and a half times as much. Where the Seagate Portable still makes sense: a small, cheap second copy of one laptop, or moving files between two computers. Don't make it the only home for your photos.
Desktop external drives use full-size 3.5-inch hard drives with their own power adapter. They're bigger, cheaper per terabyte, and much safer from drops, because they sit on a shelf and don't move. For a household or small-office backup, this is the section to buy from. Put the drive somewhere cool and ventilated, plug it into a surge protector (see Issue 01), and set your backup software to run on a schedule.
Pick 04 · Best overall backup drive (Desktop)
WD Elements Desktop (6–20TB, USB 3.0)
4.5 / 5·DX·12D
Form factor3.5" with power adapter
Capacities6–20TB
Warranty2 years
SoftwareNone (plain drive)
Typical price~$380* (8TB) · ~$550* (16TB)
This is the backup drive I'd actually set up in most homes. It's a plain 3.5-inch drive in a simple case, with a 2-year warranty, and no software or encryption layer between you and your files. That last part matters more than it sounds. If the case's circuit board ever fails, a plain drive like this is about as simple to recover as it gets. In the first days of October the 8TB ran about $380 and the 16TB about $550, roughly $34 per terabyte at 16TB.
It isn't the cheapest per terabyte. The Seagate below wins that at the very top end. What earns the Elements its 4.5 is the warranty, the plain design, and WD's showing in the August reliability study. Compare before you buy, though. On the day I checked, WD's own My Book 8TB was about $50 cheaper than the Elements 8TB. The My Book adds backup software and hardware encryption, with the same password and recovery trade-off as the My Passport above. At 16TB the Elements was far cheaper. Prices are moving fast, so check both.
⚠ Field noteWhich drive is inside isn't published, and it changes. Over the years, larger Elements desktops have often shipped with WD's own enterprise-class drives, which is why shuckers like them. But WD doesn't promise any specific drive, and smaller capacities have varied. For a backup drive that stays in its case, it doesn't matter. If you're buying it to shuck for a NAS, see the shucking notes above and check recent buyer reports first.
Strong points
Plain drive, no encryption layer, simple to recover
If you need the most space for the least money, this is it. In the first days of October the 24TB was about $690, or about $29 per terabyte, the lowest in this guide. The 16TB was about $516. Seagate also includes Rescue Data Recovery Services. That's a real perk, and one most people don't know they have until they need it.
Here's why it gets a 3.5 and not more. The warranty is just 1 year on a drive you'll realistically keep for five years or longer. Like WD, Seagate doesn't publish which drive is inside. Some of Seagate's smaller desktop drives are SMR, which is fine for backups but a gamble if you plan to shuck it for a NAS. Shop the sizes carefully, too. On the day I checked, the 22TB listing was priced higher than the 24TB. In this market, a bigger drive can sometimes cost less.
⚠ Field noteWarranty replacements aren't what they used to be. In the shortage, at least one drive maker has been reported offering refunds at the original purchase price instead of replacement drives. That's a refund that won't buy the same drive today. Don't count on a warranty to make you whole. Count on having a second copy.
Strong points
Lowest cost per TB in this guide (~$29/TB at 24TB)
Every drive in this guide will fail eventually. The question is whether you'll have another copy when it does. The rule I give everyone is 3-2-1: three copies of anything you care about, on two different kinds of storage, with one copy somewhere other than your house. In practice, that means your computer, plus one of these drives running a scheduled backup, plus a cloud backup. Issue 07 covers the cloud side. If you've outgrown single drives, Issue 08 covers NAS boxes, which keep two drives mirrored so one failure doesn't cost you anything.
One more thing about drives that sit unplugged in a drawer for years: they're not an archive. Check them once or twice a year by plugging them in, opening a few files, and copying anything irreplaceable to a newer drive before the old one reaches the age where failure rates climb.
