Best Amazon Prime Day SSD deals

XPG Gammix S55 M.2 2230 | 512 GB | NVMe | PCIe 4.0 | 5,000 MB/s read | 3,700 MB/s writes | $49.99 at Newegg
Buy the cheapest Steam Deck you can find and then slap one of these into it for a welcome boost in storage capacity and performance. It's as basic as they come but in this case, that's a good thing as you're not paying for anything you won't need.

Price check: Walmart $49.99

Team Group MP44L | 1 TB | M.2 2280 | PCIe 4.0 | 5,000 MB/s read | 4,500 MB/s write | $79.99 $56.99 at Newegg (save $23)
The MP44L is far from being the fastest SSD you can buy but for the money, you really can't complain. The read/write speeds are pretty low compared to others in our curated list, but they're still fast enough for most users and way better than a SATA SSD. If you avoid using it for heavy data transfers, you'll have no problems with it.

Lexar NM790| 1 TB | NVMe | PCIe 4.0 | 7,400 MB/s read | 6,500 MB/s write | $99.99 $74.99 at Amazon (save $25)
For anyone looking for a cheap, spacious drive offering serious performance, here you're getting a genuinely brilliant SSD for the money, and you can see this for yourself with our review of the 4 TB version.

WD Black SN850X | 1 TB | NVMe | PCIe 4.0 | 7,300 MB/s read | 6,300 MB/s write | $114.99 $74.99 at Amazon (save $40)
This is still our favorite SSD for gaming right now. Unlike the cheaper SN770, the SN850X encapsulates the best PCIe 4.0 offers in terms of performance (check out our review). That makes it a great fit for a boot drive with space to spare for your game library, and at this price, we're happy to pay the premium for its higher speed.

Price check: Best Buy $120.99 

Nextorage NEM-PAB | 1 TB | NVMe | PCIe 4.0 | 7,400 MB/s Read | 6,100 MB/s write | $149.99 $74.99 at Newegg (save $75)
Nextorage may be a relatively new name in the world of NMVe SSDs but don't be fooled by appearances. This drive uses the ubiquitous Phison E18 controller, and the 1 TB version represents excellent price/performance value here. This is the version without a DRAM cache, making it a little less responsive than the DRAM-equipped NEM-PA model, despite having a slight advantage in stated straight-line performance. Check out our review of the NEM-PA for more.

Crucial MX500 | 1 TB | 2.5" | SATA 6 Gb/s | 560 MB/s read | 510 MB/s write | $104.99 $80.97 at Newegg (save $24.02)
Not enough M.2 NVMe slots on your motherboard for more storage? No problem—you can still install a speedy SSD via a SATA port. The Crucial MX500 is pretty much the best out there, as nothing else offers the same blend of performance and value for money as the MX500. It's also available in 2 TB and 4 TB sizes, with the prices scaling on par with the storage capacity.

Price check: Amazon $82.05

Lexar Play 2230 | 1 TB | NVMe | PCIe 4.0 | 5,200 MB/s read | 4,700 MB/s write | $109.90 at Amazon
For Steam Deck upgrades, the Lexar Play is our new favorite and you can see why in our full review. It's fast for a 2230 size format, with great sustained performance. It also runs cool, even under a heavy load. The only negative is the fact that 1 TB is the largest capacity available and its price is volatile.

Crucial T700 | 1 TB | NVMe | PCIe 5.0 | 11,700 MB/s read | 9,500 MB/s write | $151.99 $139.99 at Newegg (save $12)
If you absolutely must have the fastest possible SSD then you need to get a Gen5 model. Crucial's T700 is ridiculously quick, as we found when we tested a preview sample, but the high price and running temperatures spoil the picture somewhat. Probably best to wait for the next round of Gen5 SSDs before taking the plunge.

Price check: Amazon $162.99 (w/ heatsink)

Silicon Power UD90 | 2 TB | NVMe | PCIe 4.0 | 5,000 MB/s read | 4,800 MB/s write | $144.97 $98.97 at B&H (save $46)
You might not know Silicon Power from Samsung, but this SSD comes well reviewed by our friends at Tom's Hardware. It offers plenty of speed for a Steam library expansion but with a frightfully low cost per gigabyte of just five cents. That's one of the best I've seen all Prime Day.

Price check: Newegg $98.97

Team Group MP44L | 2 TB | NVMe | PCIe 4.0 | 4,800 MB/s read | 4,400 MB/s write | $139.99 $105.99 at Newegg (save $34.00)
There's no DRAM to boost sustained performance and the SLC cache isn't especially big, either. But the speed is good enough for most workloads and when 1 TB of storage costs this much, who cares that it's not flash or fancy? Not us, that's for sure.

Price check: Amazon $105.99

Nextorage G-LE | 2 TB | NVMe | PCIe 4.0 | 7,400 MB/s read | 6,400 MB/s write | $249.99 $114.99 at Newegg (save $135)
This DRAM-less Nextorage drive still has plenty of pace about it, and if you're just using it as an extra game library SSD to contend with your expanding library, but still need some storage speed, it's a great option. The extra cache can come in handy as a boot drive, increasing responsiveness for smaller write operations, but for games, this more affordable option can be a good way to save some cash on a new build or upgrade.

Nextorage NEM-PAB | 2 TB | NVMe | PCIe 4.0 | 7,300 MB/s read | 6,900 MB/s write | $249.99 $119.99 at Newegg (save $130)
You can expect top performance out of this drive, which is impressive for the price. This is the version without a DRAM cache, making it a little less responsive than the DRAM-equipped NEM-PA model, despite having a slight advantage in stated straight-line performance. Unfortunately, this drive's price is volatile, but it's still one of the better-value 2 TB drives with a heatsink right now.

Price check: Amazon $139.99

Lexar NM790 | 2 TB | NVMe | PCIe 4.0 | 7,400 MB/s read | 6,500 MB/s write | $134.99 at Amazon
This SSD is a great deal right now and Lexar has put together a superb SSD in the NM790. Thanks to high-layer NAND and a low-power controller, you get tons of storage here on an energy-efficient and great-performing drive for not much cash and often much less cash than the competition. Read our Lexar NM790 (4 TB) review for more.

Price check: Newegg $149.99

Team Group MP44S M.2 2230 | 2 TB | PCIe 4.0 | 5,000 MB/s read | 3,500 MB/s write | Steam Deck + ROG Ally compatible | $136.96 at Amazon
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 drive 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.

Price check: Newegg $136.99

Silicon Power XS70 | 2 TB | NVMe | PCIe 4.0 | 7,300 MB/s read | 6,800 MB/s write | $179.99 $149.99 at Amazon (save $40)
Prices for the XS70 are some of the most variable I've seen for an SSD, so it's perhaps worth waiting to see if the price dips again before picking one up. It packs rather a large bang for your buck with its fast read and write times, at least. While the software side of things may be a little lacking, we were impressed with this drive's overall performance and value proposition.

Price check: Newegg $230.60

WD Black SN850X | 2 TB | NVMe | PCIe 4.0 | 7,300 MB/s read | 6,300 MB/s write | $189.99 $139.99 at Amazon (save $50)
Our favorite SSD for gaming right now encapsulates the best PCIe 4.0 offers in terms of performance (check out our review). That makes it a great fit for a boot drive with space to spare for your game library but while it's super fast and reliable, prices are really volatile.

Price check: Newegg $154.99 | Best Buy $120.99 

Team Group QX | 4 TB | 2.5" | SATA III 6 Gb/s | 560 MB/s read | 510 MB/s write | $192.99 $188.99 at Newegg (save $4)
It's a fair chunk of cash for a slow SSD but if you're looking for lots of storage and don't need a blazing NVMe drive, then this is the cheapest way of putting a 4 TB SSD in your gaming PC. Just don't expect it to sustain full speed under heavy workloads and you'll be fine.

Price check: Amazon $188.99

Silicon Power UD90 | 4 TB | NVMe | PCIe 4.0 | 5,000 MB/s read | 4,500 MB/s write | $239.99 $219.99 at Amazon (save $20)
This Silicon Power might not be the fastest of drives, but it's difficult to argue with this much storage for this sort of money. With a sequential read/write of 5,000 MB/s and 4,500 MB/s, it's still not what you'd call slow and should be fine for gaming, plus it comes from a reliable brand.

Team Group MP44 | 4 TB | NVMe | PCIe 4.0 | 7,400 MB/s read | 6,900 MB/s write | $299.99 $222.99 at Amazon (save $77)
This Team Group boasts some mighty specs for the money, though it's actually the same hardware as in the Lexar NM790. The sequential read/write speeds are extremely high but it can only sustain them over short bursts. At this price, it's well worth putting up with that limitation.

Silicon Power XS70 | 4 TB | NVMe | PCIe 4.0 | 7,200 MB/s read | 6,800 MB/s write | $309.99 $259.99 at Amazon (save $50)
High-performance 4TB SSDs are starting to rocket in price but if you absolutely must have one, this is an excellent choice. Mountains of storage, blistering speed—this XS70 has them both, but you'll be paying a pretty penny for it. At least it comes with a decent heatsink to keep temperatures under control.

Team Group PD20M | 1 TB | USB 3.2 Gen2x2 | 2,000 MB/s read | 2,000 MB/s write | $99.99 $79.99 at Newegg (save $20)
Not all external SSDs need to be big and bulky. This Team Group PD20M is just 40 g in weight and 8.2 mm thick, making it very portable. It's also MagSafe-compatible so you can attach it to the back of an iPhone and extend its storage, with an appropriate cable. As with all fast external SSDs, you'll need a USB 3.2 Gen2x2 (20 Gbps) port to get the full speed.

Price check: Amazon $79.99

Crucial X9 Pro | 2 TB | USB 3.2 Gen2 | Up to 1,050 MB/s read and write | $169.99 $119.99 at Best Buy (save $50)
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.

Samsung T7 Shield | 4 TB | USB 3.2 Gen2 | Up to 1,050 MB/s read and write | $499.99 $283.08 at Amazon (save $216.91)
You might think this is a lot of money for an external SSD, and you'd be right. But that's not to say it's a bad deal. In fact, it's one of the best deals in this list, at just under $0.06 per gigabyte. You're paying less, for more. Now I sound like Nvidia CEO Jensen Huang... "the more you buy, the more you save."

Crucial BX500 | 500 GB | 2.5" | SATA 6 Gb/s | 550 MB/s read | 500 MB/s write | £26.99 at Scan
For just storing documents, this small SATA SSD is a lot faster than a traditional HDD and Crucial has an excellent reputation for reliability and quality. You're still better off getting an NVMe M.2 SSD for games and your operating system, though.

Price check: Amazon £29.82

Crucial MX500 | 1 TB | 2.5" | SATA 6 Gb/s | 560 MB/s read | 510 MB/s write | £75.17 £72 at Amazon (save £3.17)
If you don't have enough M.2 NVMe slots on your motherboard for more storage, don't worry; you can still install an SSD via a SATA port. The Crucial MX500 is pretty much the best one out there, as nothing else offers the same blend of performance and value for money as the MX500. It's also available in 2 TB and 4 TB sizes, with the prices scaling on par with the storage capacity, though it is much slower than an NVMe drive.

Lexar NM790 | 2 TB | PCIe 4.0 | 7,400 MB/s read | 6,500 MB/s write | £123.99 £114.06 at Amazon (save £9.93)
Lexar has put together a superb SSD in the NM790, and the best part is that it's surprisingly cheap. Thanks to high-layer NAND and a low-power controller, you can get tons of storage here on an energy-efficient and great-performing drive for not much cash and often for much less cash than the competition. Read our Lexar NM790 (4 TB) review for more.

WD Black SN850X | 2 TB | NVMe | PCIe 4.0 | 7,300 MB/s read | 6,300 MB/s write | £135.00 at Amazon

It's a fair chunk of cash for a slow SSD but if you're looking for lots of storage and don't need a blazing NVMe drive, then this is the cheapest way of putting a 4 TB SSD in your gaming PC. Just don't expect it to sustain full speed under heavy workloads and you'll be fine.

Crucial X10 Pro | 2 TB | USB 3.2 Gen2x2 | Up to 2,100 MB/s read | Up to 2,000 MB/s write | £229.99 £161.99 at Scan (save £68)
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.
