The T7 is the default portable SSD recommendation and has been for several generations. It is about the size of a credit card and considerably lighter than anything mechanical, the aluminium case helps it shed heat under sustained transfers, and it carries the highest owner rating of any drive on this page.
USB 3.2 Gen 2 is the interface most laptops actually have, so the stated speeds are achievable rather than theoretical — unlike the faster Gen 2x2 drives, which need a port most machines do not carry.
It ranks first because it is the best balance here: fast enough to work from, small enough to forget in a pocket, and proven across a very large owner base.

Where the Samsung is a desk and bag drive, this is built for sites, fields and weather. The rubberised shell and IP rating mean rain and dust are not a problem, and the carabiner loop clips it to a bag or a belt rather than leaving it loose in a pocket.
It carries roughly twice the Samsung's owner record — the deepest of any SSD on Amazon UK — and its stated 1050MB/s read speed is marginally ahead.
It ranks second because for most people the Samsung's smaller, lighter form is the more useful design, and this one costs more. For anyone photographing or filming outdoors, reverse that order.

Nothing else on this site has an owner record like this one: over a quarter of a million ratings on Amazon UK, holding a 4.7 average. For a product whose entire job is not to lose your data, that is the most meaningful evidence available anywhere in this category.
It is a plain mechanical drive with no software, no encryption and no frills — you plug it in and it appears. That simplicity is part of why it rates as well as it does, and it gives roughly twice the capacity of the SSDs above for less money.
The limits are the ones every mechanical drive has: slower, larger, and not to be knocked while it is running. For backups and archives, neither matters.

Pros
+ Over a quarter of a million owner ratings at 4.7 — the strongest evidence on this page
+ Roughly twice the capacity of the SSDs above for less money
+ No software or setup; it simply appears when plugged in
+ Well-proven design sold for years
Cons
− Mechanical, so far slower than an SSD
− Must not be moved while reading or writing
− No encryption or backup software included
− USB 3.0 with a USB-A cable, so recent laptops may need an adapter
My Passport is WD's step up from the Elements above: the same class of mechanical drive with 256-bit hardware encryption and WD's own backup software included.
The encryption is the reason to choose it. A portable drive holding a copy of everything is a genuine risk if it is lost or stolen, and hardware encryption with a password means a found drive is useless to whoever finds it. For a drive that leaves the house, that is worth the modest premium.
It ranks below the Elements because the Elements' owner record is over twice as deep and its rating slightly higher, and because plenty of people are better served by the operating system's own backup tools.

Pros
+ 256-bit hardware encryption — a lost drive is useless to a finder
+ Backup software included
+ Very deep owner record

Cons
− Costs a little more than the Elements for the same capacity
− Mechanical, with the same speed and fragility limits
− Bundled backup software is less useful than the system's own for most people
Seagate's Portable Drive is the direct competitor to the WD Elements and the two are closely matched: the same plain mechanical formula, no software, and an enormous owner record. This one is cheaper and rates marginally lower.
There is genuinely little to choose between them, and buying whichever is cheaper on the day is a reasonable strategy. The WD's slightly higher rating across a comparable sample is the only thing separating them, which is why it ranks above.
Like every mechanical drive here, treat it as a device that lives still while it works.

The practical problem with the WD and Seagate drives above is the cable: both are supplied with USB-A, and a recent laptop may not have a USB-A port. The Canvio Partner ships with both cables, which sounds trivial and is exactly the kind of thing that turns a new drive into a trip to buy an adapter.
Otherwise it is a conventional 2.5-inch mechanical drive at a conventional price, with a shallower owner record than the giants above it — though twelve thousand ratings is still substantial evidence.
It ranks here because the cable convenience is real but small, and the WD and Seagate drives have far more owner evidence behind them.

This is a different tool for a different job. It is not a backup drive and should not be used as one; it is for carrying a few files between devices, plugging into a phone to clear photos off it, or taking a document to a print shop.
The dual connector is the whole design: USB-C on one end and USB-A on the other, retracting into the body so there is no cap to lose. That covers phones, tablets, recent laptops and older machines without an adapter.
At the price and with seventy thousand ratings behind it, it is the most useful small thing here. It ranks last because it holds a fraction of what the others do, and because a flash drive is not a backup.

Rankings are built from the specifications published in the Amazon UK listing and on the manufacturer's UK site — interface, stated read speed, capacity, physical protection rating and bundled software — set against owner ratings and review counts at scale on Amazon.co.uk, and reviews published by other outlets. Nothing here is bought, tested or handled, and no transfer speed quoted here is a measurement.
Both SanDisk and Samsung pool one review count across every capacity of a model, so the figures describe the model rather than a particular size. One canonical listing per model is ranked.

If you will edit video, run a photo library or boot software from the drive, buy an SSD — the speed difference is the whole point and a mechanical drive will frustrate you. If the drive exists to hold a backup or an archive you open occasionally, mechanical gives roughly twice the capacity for the money and the speed never matters.
Check the connector on both ends
Most portable drives now use USB-C at the drive end, but what is in the box varies: some include a USB-C to USB-C cable, some USB-C to USB-A, some both. If you have a recent laptop with only USB-C ports, a drive supplied with a USB-A cable needs an adapter. The listing photographs usually show what is included.
Mechanical drives should not be moved while running
A mechanical drive has a spinning platter and a head floating above it. Knocking one while it is reading or writing is the most common cause of failure. If the drive lives in a bag and gets used in different places, an SSD is worth the money for that reason alone, regardless of speed.
An IP rating means it survives a building site, not a swimming pool
Rugged SSDs like the SanDisk Extreme carry IP ratings for dust and water resistance, which makes them genuinely suited to outdoor and site work. It is protection against rain, dust and a drop onto grass, not an invitation to submerge them. For a drive that lives on a desk, the rating adds cost for nothing.
A backup on one drive is not a backup
Whichever you buy, a single copy on a single drive is one failure away from nothing. The widely used rule is three copies, on two different kinds of media, with one kept somewhere else — a portable drive plus a cloud service is the simplest way most households reach it. Drives fail, and the cheap ones and the expensive ones both do.
This is the category where the sensible answer and the exciting answer differ most. Portable SSDs are faster, smaller and tougher, and the tech press writes about little else. The two best-selling portable drives on Amazon UK are both mechanical — the WD Elements and the Seagate Portable — and between them they carry over half a million owner ratings.
That is because for the job most people actually have, which is backing up a laptop or storing a photo library, capacity per pound matters more than speed. A mechanical drive gives roughly twice the storage for the same money, and a backup that runs overnight does not care how long it takes.
So this list covers both, with the tier telling you which is which. There is also a genuine finding worth stating: only two portable SSD models on Amazon UK have meaningful owner depth. Targeted searches for the Samsung T7 Shield, Crucial X9, Kingston XS2000 and Seagate One Touch SSD found none with a substantial review record, which is why this list leans the way it does.
Portable Storage — Frequently Asked Questions
Should I buy an SSD or a mechanical hard drive?+
It depends entirely on whether you will work from the drive or store things on it. If you will edit video, run a photo library or launch software from it, buy an SSD — the speed difference is the point. If it exists to hold a backup or an archive, a mechanical drive gives roughly twice the capacity for the same money and the speed never matters, because a backup that runs overnight does not need to be fast. The two best-selling portable drives on Amazon UK are both mechanical for exactly this reason.
Are mechanical drives less reliable?+
They fail differently rather than more often. A mechanical drive has a spinning platter and a head floating above it, so it is vulnerable to being knocked while it is running — that is the main cause of failure and it is entirely avoidable. An SSD has no moving parts and survives being dropped, but when it fails it tends to fail suddenly and completely, where a mechanical drive often gives warning. Whichever you buy, one copy on one drive is not a backup.
What does an IP rating on a drive mean?+
It is a standardised measure of resistance to dust and water. On a rugged SSD like the SanDisk Extreme it means the drive will survive rain, dust and site conditions — genuinely useful if you photograph or film outdoors. It is not a rating for submersion, and for a drive that lives on a desk it adds cost for no benefit.
Will these work with both Windows and Mac?+
Yes, though some arrive formatted for Windows and need reformatting for a Mac, which takes a minute and erases the drive. Check the listing, which usually says. The one thing to watch is bundled backup software, which is often Windows-only — the drive itself will work regardless, but that extra will not.
Why are there so few portable SSD brands on Amazon UK?+
Because only two models have real owner depth there: the SanDisk Extreme and the Samsung T7. Targeted searches for the Samsung T7 Shield, Crucial X9 and X10, Kingston XS2000 and Seagate One Touch SSD found none with a substantial review record on Amazon UK. They are sold in Britain — largely through Currys, Scan and Overclockers — but the Amazon shelf is effectively two SSD models and a set of mechanical drives, which is why this list is shaped the way it is.
