A backup only helps if it exists before the laptop dies, and an external drive is still the simplest way to make one. After going through UK roundups, spec sheets and amazon.co.uk listings, the best external hard drive for most people is the WD My Passport 4TB: plenty of space, hardware encryption and backup software in a pocket-sized shell.
I didn't test these hands-on. The list mixes portable hard drives, one desktop drive and three portable SSDs, because the best hard drive for nightly backups isn't the best one for editing video. Six picks have UK roundup backing; the rest are judged on their listings.

What each drive is for, what the link buys, and where it falls short.
#1 · Editor's Choice
Plug it in, let the backup software run overnight, and forget about it: that's the job the WD My Passport does best. This link is the 4TB model in black, a 5400rpm portable drive on USB 3.2 Gen 1 with 256-bit AES hardware encryption, password protection and a 3-year limited warranty. At about 210g it lives happily in my laptop bag. A UK roundup names it its top hard drive. It isn't quick, though: expect roughly 120-130MB/s, so a first full backup takes an evening, and the Micro-B lead feels dated next to USB-C.
The verdict: The best hard drive for most people who want roomy, encrypted backups they can carry.
#2 · Runner-Up
If your backups live on a desk rather than in a bag, this is the better buy. The Seagate Expansion Desktop gives you 8TB in a full-size desktop drive over USB 3.0, with drag-and-drop saving and two years of Rescue Data Recovery Services. That's enough room for every laptop in a busy household, and the same UK roundup that rates the My Passport picks this model line for desktop backup. Mine would sit under the desk beside the PC. The trade-off is power: it needs its mains adapter and a free socket, and Mac owners must reformat it for Time Machine.
The verdict: The most storage here, for a fixed home backup that never leaves the desk.
#3 · Fastest Portable SSD
Two thousand megabytes a second is the headline, and it holds only on the right port. Not fast everywhere, then: fast on a USB 3.2 Gen 2x2 socket, which many laptops lack. The Samsung T9 is a 1TB NVMe portable SSD rated up to 2,000MB/s read and write, weighing 122 g and rated for drops of up to 3 metres, with both USB-C to C and C to A cables and a 5-year limited warranty. For video editing straight off the drive, that's worth having. For plain backups, the My Passport gives you four times the space.
The verdict: The fastest drive here, worth it if you edit from it rather than just back up to it.
#4 · Best Budget
Buy this if you want a backup drive and nothing else to think about. The Canvio Basics is a 2TB 5400rpm portable hard drive with a matte, smudge-resistant finish, USB 3.0 and no software to install, and it needs no mains lead. A UK testing roundup includes it. At about 150g, it barely registers in a coat pocket. That simplicity has a cost, though: there's no encryption or backup app, and it's pre-formatted NTFS for Windows, so Mac owners need to reformat it first.
The verdict: The no-fuss budget pick for a Windows laptop backup.
#5 · Best Rugged HDD
Picture a camera bag dropped on a station platform; this is the drive built for that moment. LaCie's Rugged USB-C model, here in its 2TB version, carries a MIL-STD-810F drop rating up to 1.2 m, IP52 dust and drip protection and 1 tonne crush resistance, plus 256-bit AES encryption, Rescue Data Recovery Services and a 3-year limited warranty. A UK roundup covers it. Inside, though, it's still a 5400rpm disk at about 130MB/s, no quicker than the Toshiba Canvio Basics, and 2TB fills fast with video.
The verdict: The tough, encrypted hard drive for photographers and fieldwork.
#6 · Best Value SSD
Think of the Crucial X9 as the sensible middle ground between a slow hard drive and the Samsung T9. It's a 2TB portable SSD rated up to 1,050MB/s read over USB 3.2 Gen 2, with a USB-C to C cable included, and it works with Windows, Mac, Android, iPad, Xbox and PlayStation. At 65 x 50 x 10mm it disappears into a coin pocket. A UK roundup includes it. It's drop, shock and vibration resistant, but there's no water rating, unlike the SanDisk Extreme, and no write speed on the listing.
The verdict: The best-value SSD here for console games and fast laptop backups.
#7 · Best for Photographers
If your drive spends weekends clipped to a backpack, this is the SSD I'd choose. The SanDisk Extreme 2TB uses NVMe flash for up to 1,050MB/s read and 1,000MB/s write over USB-C, adds IP65 dust and water resistance and a 3-metre drop rating, and has a carabiner loop for a belt or bag strap. Password protection with 256-bit AES hardware encryption is included. It appears in two UK roundups. My only gripe is the Memory Zone app, which I'd happily skip; companion apps rarely earn their place on my laptop.
The verdict: The rugged SSD for photographers who work outdoors.
#8 · Best for Consoles
Got a PS4 or Xbox One short on space? Silicon Power lists the Armor A60 for both, with PS4 system software 4.50 or later. It's a 2TB 5400rpm hard drive in a shockproof, IPX4 water-resistant shell, with a cable-carry design so the lead doesn't wander off. It comes pre-formatted NTFS for Windows, and Mac users have to reformat it. It's judged on its listing alone, and at about 135 x 89 x 20mm it's chunkier than the Toshiba.
The verdict: A tough, console-friendly hard drive, if you don't mind the bulk.
#9 · Best for Windows Backups
Mac owners can skip this one, since the bundled Nero BackItUp software is Windows only. On a Windows PC, though, the Store 'n' Go makes scheduled backups easy: the software backs up files, folders or whole drives on a timetable you set. The drive itself is a 2TB USB 3.0 portable hard drive, bus powered and backwards compatible with USB 2.0 ports. The linked listing is the silver version. There's no encryption or rugged casing, and no roundup we read covered it.
The verdict: A simple scheduled-backup drive for Windows households.
#10 · Best Waterproof Drive
Of all the drives here, this has the highest water rating. The ADATA HD710 Pro is IP68 rated, meets MIL-STD-810G 516.6 for falls from 1.5 metres, and with its port cover fully closed survives being submerged 2 metres deep for 60 minutes. The detachable cable wraps into a groove around the shell. Inside it's a 2TB 5400rpm drive on USB 3.1, so speed is ordinary. The link is the red one, it's big at about 300g, and it ranks on its listing alone.
The verdict: The waterproof hard drive for boats, beaches and muddy shoots.
We didn't test these hard drives hands-on or in a lab. The ranking is built from UK and international editorial roundups, manufacturer spec sheets and amazon.co.uk listings, checked against one another. The WD, Seagate, Toshiba, LaCie, Crucial and SanDisk picks appear in UK roundups; the Samsung T9 and the other three are judged on their published specs. Where research data and a listing disagreed, as with the Intenso's capacity, I followed the listing title.
What we compared for every drive:
How we weighted the scores:
Start with the type. A portable hard drive (HDD) spins a disk, usually at 5400rpm, and moves files at roughly 120-130MB/s; it's slower and less fond of drops, but you get far more space for your money, which is why the WD My Passport and Seagate Expansion Desktop top this list. A portable SSD such as the Samsung T9, Crucial X9 or SanDisk Extreme has no moving parts, copes better with knocks and runs many times faster. For a weekly backup the speed rarely matters; for editing video or carrying a game library, it does.
Portable drives draw power over USB, so one cable does everything. A desktop drive like the Seagate needs a mains adapter and a socket, but packs more storage and can run backups every night from a home office shelf.
Check the connector and format, too. Several of these use Micro-B leads, while the LaCie, Samsung, Crucial and SanDisk use USB-C. Many drives arrive formatted for Windows, so Mac owners should expect to reformat. If the data is sensitive, look for hardware encryption: the WD, LaCie and SanDisk offer password protection, and the iStorage diskAshur2 (the link is the blue 2TB model) adds a PIN keypad.
On budget, the Intenso, UnionSine, Verbatim, Toshiba and ADATA are entry-level, the WD, LaCie, Crucial, Silicon Power and Buffalo are mid-range, and the Samsung, SanDisk, Seagate 8TB and iStorage sit at the premium end. Want one drive that just works for a family laptop? Buy the WD My Passport and call it a day.

For most people, the WD My Passport 4TB: lots of space, 256-bit AES hardware encryption and backup software in a pocket-sized drive. For a desk-bound family backup, the Seagate Expansion Desktop 8TB holds more. If you need speed rather than space, a portable SSD like the Crucial X9 or Samsung T9 is the better buy.
For plain backups, a hard drive gives far more space for the money, and its speed rarely matters overnight. An SSD is faster, smaller and copes better with knocks, so it suits laptops on the move, video work and game libraries. Plenty of people use both: a big hard drive at home and a small SSD in the bag.
No single brand wins, but WD, Seagate, Toshiba, Samsung, Crucial, SanDisk and LaCie are the names that turn up most in UK roundups. Judge the specific model instead: capacity, connector, warranty, and whether it includes encryption or backup software. Lesser-known brands like Intenso or UnionSine can work, but they have less editorial backing.
Neither is clearly better; they suit different setups here. The WD My Passport is a portable drive with hardware encryption and a 3-year limited warranty, while the Seagate Expansion Desktop is a mains-powered 8TB drive with two years of Rescue data recovery. Choose WD for a laptop bag and Seagate for a desk.
Yes, but many arrive formatted for Windows. The Toshiba Canvio Basics and Silicon Power Armor A60 ship as NTFS and need reformatting on a Mac, and the Seagate needs reformatting for Time Machine. Reformatting wipes the drive, so do it before you copy anything across. Verbatim's bundled backup software is Windows only.
Ideally three: your original plus two backups, with one kept somewhere else. A practical home version is a desktop drive like the Seagate for nightly backups and a portable drive kept at work or with family. A NAS or cloud service can be the offsite copy, though that's a bigger setup than one external drive.
For most people, the WD My Passport 4TB is the best external hard drive to buy: roomy, encrypted and easy to carry. If your backups never leave the desk, the Seagate Expansion Desktop 8TB holds twice as much. Need speed for video or games? The Crucial X9 is the value SSD and the Samsung T9 the fastest. Whichever you pick, set the backup to run automatically.
