Lexar NM790 | 1 TB | NVMe | PCIe 4.0 | 7,400 MB/s read | 6,500 MB/s write | $99.99 $67.37 at Amazon (save $27.62)
For anyone looking for a cheap, spacious drive offering serious performance, this is a genuinely brilliant SSD for the money. Our review of the 4 TB version clearly shows just how good it is.

Samsung 990 Evo Plus | 2 TB | NVMe | PCIe 4.0 | 7,250 MB/s read | 6,300 MB/s write | $176.99 $113.99 at Amazon (save $63)
Samsung's relatively new 990 Evo Plus range has a lot going for it (check out our review) but its launch price was too high. This deal goes a long way to rectify that but for a DRAM-less SSD, it's still a bit pricey. If you're a fan of Samsung's excellent Magician software, then it's worth considering, but there are SSDs for less money that are just as good.

WD_BLACK SN7100 M.2 2280 | 2 TB | NVMe | PCIe 4.0 | up to 7,250MB/s read | up to 6,900MB/s write | $149.99 $134.20 at Newegg (save $15.79)
Presenting only small gains over the SN850X, this SSD is no slouch and still offers some of the best in class 4K read performance (read our full review of the 1 TB model). Though this drops the DDR4 DRAM cache and instead opts for a single-sided drive design, it's still got the same versatile form factor that perfectly suits this heat-sinkless drive to PCs, consoles, and laptops.

Crucial P310 2280 | 4 TB | NVMe | PCIe 4.0 | Up to 7,100 MB/s read | up to 6,000 MB/s write | $333.99 $199.99 at Amazon (save $134)
This budget SSD is packing in a lot of space for just under $0.05 per GB, and while it might be QLC memory and comes without DRAM cache, it's still an impressively quick drive for the money, with strong sequential performance.

Crucial P310 | 1 TB | NVMe | PCIe 4.0 | 7,100 MB/s read | 6,000 MB/s write | $134.99 $79.99 at Amazon (save $55)
This is a decent saving on a 2230 format SSD that performs pretty nicely, as we found when we reviewed the 2 TB version. Crucial's performance claims are very much peak values and the real-world numbers are generally lower, but at this price, it's a great way to boost your Steam Deck's storage and get a handy speed bump. There are cheaper 2230-size SSDs to be found but they're not as fast as this one.

Team Group MP44S M.2 2230 | 2 TB | NVMe | PCIe 4.0 | 5,000 MB/s read | 3,500 MB/s write | Steam Deck + ROG Ally compatible | $169.99 $132.99 at Newegg (save $37)
This Team Group drive isn't the fastest compact SSD you can stick in your Steam Deck, but it is one of the cheapest 2TB drives you'll be able to find for your wee handheld gaming PC. And it will also be a little quicker than the stock drive the Deck ships with, too.

Crucial X9 Pro | 2 TB | USB 3.2 Gen2 | Up to 1,050 MB/s read and write | $149.99 $102.99 at Best Buy (save $47)
Crucial is a big name in SSDs, and the Micron-owned brand is offering a small saving on this 2 TB external model. The drive comes in an anodized aluminium shell with a rubberized base and is just 65 x 50 mm big. There's an integrated lanyard hole too, if you want to wear it, which hides a drive activity light.

Crucial X10 Pro | 2 TB | USB 3.2 Gen2x2 | Up to 2,100 MB/s read | Up to 2,000 MB/s write | £189.99 £145.99 at Amazon (save £45)
If you need a small external SSD but don't want to sacrifice capacity or performance, then Crucial's X10 Pro is a great choice. It's the same size as the X6 model but has double the read/write performance, though you will need to plug it into a 20 Gbps USB port to reach full speed.
