Rank #1
SanDisk Extreme Portable SSD 1TB, up to 1050MB/s read, USB-C
Our Verdict
A rubberised, IP-rated SSD with a carabiner loop, the one to take outdoors.
Why it's number one: The deepest owner record of any SSD here, an IP rating for rain and dust, and two published reviews of this exact drive, from Tom's Hardware and TechAdvisor.
It is close: The Samsung T7 is effectively tied and has the higher owner rating, in a smaller and lighter body, but only one outlet has published a score for it, so it cannot take the top slot. Amazon UK also now lists this SanDisk as the older model. For a bag and a desk, the Samsung T7 is the better design; for outdoor and site work, buy the SanDisk.

OwnersExcellent owner rating from a very deep record on Amazon UK
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.
For most people the Samsung T7's smaller, lighter form is the more useful design. For anyone photographing or filming outdoors, reverse that order.
Amazon UK now labels this listing as the older model. SanDisk has released a newer Extreme rated at up to 2,000MB/s, which needs the same uncommon USB 3.2 Gen 2x2 port as the Samsung T9 to reach that figure and has a thin owner record so far.

How we scored it
Each measure is marked against the category's rubric, where 10 is the best you can buy, 8 is strong, 6 is basic but sound and 4 falls short. The bars show that mark on the Top7 scale (a 6 reads as 7.0, an 8 as 8.5); the notes quote the rubric mark.
Speed 9.3 (rubric 9): Up to 1050MB/s read over USB-C, per the listing.
Capacity 7.0 (rubric 6): One terabyte.
Durability 10.0 (rubric 10): IP-rated rubberised shell, the toughest drive on this page.
Convenience 8.5 (rubric 8): Carabiner loop; bulkier than the Samsung.
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 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.

Speed 9.3 (rubric 9): USB 3.2 Gen 2 SSD, per the listing. Fast enough to work from directly.
Capacity 7.0 (rubric 6): One terabyte.
Durability 7.8 (rubric 7): Solid state with an aluminium case; no IP rating published.
Convenience 10.0 (rubric 10): The smallest and lightest drive here.
The T7 Shield answers the one complaint about the plain T7 above it: an aluminium case is fine on a desk and less reassuring in a camera bag. Samsung wraps the same drive in a rubber housing, publishes an IP65 rating for dust and water, and states it survives a fall from three metres, per the listing. The SanDisk Extreme is the other rugged SSD here; this one adds AES 256-bit hardware encryption, so a lost drive is useless to whoever finds it without the password.
Speed is the standard figure for this class, up to 1,050MB/s read over USB 3.2 Gen 2, which is as fast as most laptops' ports can go. Both cables come in the box, USB-C to C and USB-C to A, so it plugs into a new MacBook and an old desktop without an adapter.
It costs more than the SanDisk Extreme for the same capacity, and price is what three published reviews hold against it. The listing is sold by a third-party seller, dispatched by Amazon. The owner record is pooled across the Shield's capacities and colours, as with every Samsung drive here.

Speed 9.3 (rubric 9): Up to 1,050MB/s read on USB 3.2 Gen 2, per the listing, the same class as the T7 and SanDisk Extreme.
Capacity 7.0 (rubric 6): One terabyte.
Durability 10.0 (rubric 10): Published IP65 rating, a rubber housing and a stated three-metre drop figure.
Convenience 9.3 (rubric 9): Hardware encryption and both cables supplied, per the listing.
The T9 is rated at up to 2,000MB/s, twice the figure of the Samsung T7 and SanDisk Extreme, but only over USB 3.2 Gen 2x2, a port most laptops and Macs do not have. On an ordinary USB-C port it runs at much the same speed as the T7, so check your computer's specification before paying for the difference.
Where the port exists, usually on desktop PCs and some Windows workstations, it is the drive for editing video directly from external storage. It is rubberised and rated drop-proof from three metres, per the listing, with no IP rating for water or dust, and it ships with both USB-C to C and USB-C to A cables. Samsung gives it a five-year warranty.
It is larger and heavier than the T7. Two outlets have reviewed it: Expert Reviews at five stars and TechRadar at four.

Durability 8.5 (rubric 8): Solid state in a rubberised shell, drop-proof from three metres; no IP rating published.
Convenience 8.5 (rubric 8): Both USB-C to C and USB-C to A cables supplied, per the listing.
Crucial is the consumer brand of Micron, which makes memory chips, and the X9 is its plain portable SSD: up to 1,050MB/s read over USB 3.2 Gen 2, per the listing, the same interface class as the SanDisk Extreme and the Samsung T7 on this page, so on most laptops it moves files at a similar pace.
What it gives up is protection and extras. No IP rating is published for dust or water, where the SanDisk has one; the listing quotes drop protection to 7.5 feet. There is no hardware encryption, and only a USB-C to C cable comes in the box, so an older laptop with USB-A ports needs an adapter.
Its owner record on Amazon UK is very deep, pooled across its capacities, and it has published reviews of this model from PC Gamer and Creative Bloq. For backups and moving files between machines, rather than work in the rain, it is the sensible SSD here.

Nothing else on this site has an owner record like this one: the deepest in the category by a wide margin, with an exceptional average rating. 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.

Convenience 7.8 (rubric 7): Plug and play with no setup; larger than an SSD.
Pros
+ The deepest owner record in this category, at an exceptional rating
+ 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
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 a very deep owner record behind it, it is the most useful small thing here. It holds a fraction of what the others do, and 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.
Scored on Speed 35%, Capacity 25%, Durability 20%, Convenience 20%, plus owner ratings
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 portable drives with the deepest owner records on Amazon UK are both mechanical: the WD Elements and Seagate's Portable Drive.
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. The portable SSD shelf has also filled out. The Samsung T7 Shield, Crucial X9 and X10, Kingston XS2000 and Seagate One Touch SSD now each carry well over a thousand Amazon UK ratings, where none had a substantial record when this page was first built. The five SSDs ranked here cover five different jobs: a drive for a bag and a desk, a rugged one for outdoor work, a tougher one still with hardware encryption, a fast one for computers with the port to use it, and the Crucial X9 for anyone who wants SSD speed without paying for the extras. There is one mechanical drive rather than two: the WD My Passport held a place here until its listing stopped offering a new unit, and the Elements covers the same job for less.
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 or the Samsung T7 Shield 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 the Kingston and Seagate SSDs not on this list?+
They could be. When this page was first built, targeted searches of Amazon UK found none of the Samsung T7 Shield, Crucial X9 and X10, Kingston XS2000 or Seagate One Touch SSD with a substantial review record; by September 2026 each had a deep one. Two of them are now ranked: the Crucial X9 as the plain SSD for someone who wants the speed without paying for extras, and the Samsung T7 Shield as the rugged drive with hardware encryption. The Kingston XS2000, Crucial X10 and Seagate One Touch compete closely with those, and each of the five SSDs here covers a job the others do not: the Samsung T7 for a bag and a desk, the SanDisk Extreme for rain and dust, the T7 Shield for rain, dust and a password, the Samsung T9 for speed and the Crucial X9 for value.
