Amazon Prime Day deals on SSDs and external hard drives for the last day: Save on Samsung, Crucial, Sandisk and more

If you've been holding an SSD or external HDD for your PC build in a cart, waiting to take advantage of an Amazon Prime Day discount, today is your last chance to grab your hardware at that cheaper price. Solid-state drives (SSDs) come in many shapes, from thumbnail-sized microSD cards to larger external SSDs. But all classes of SSDs have one thing in common: at least one of the best brands is on sale right now. Take a look at our curated list of the best deals on external and portable SSDs, HDDs and microSD cards.

• Crucial BX500 for $57 (40 percent off): The Crucial BX500 SSD is compatible with any computer that uses a 2.5-inch SATA drive — which is still plenty of them. For very cheap, you can get ahold of 1TB storage space and read speeds up to 540 MB/s, close to the very best possible for a SATA SSD.

• WD_BLACK SN850X for $150 (25 percent off): Our current favorite Gen4 NVMe drive is on sale for Prime Day, making a read speed of over 7,000 MB/s more accessible than ever. In our tests, we found the 1TB SN850X significantly boosted our Windows operating speeds without adding much heat.

• WD Blue SN5000 for $200 (33 percent off): Here's a great deal on an internal SSD with 4TB capacity and compatibility with the fast-performing NVMe protocol. Western Digital, the same brand behind the WD_BLACK (see above) claims the Blue model can hit read speeds of 5,500 MB/s.

• Lexar 1TB NM790 for $67 (29 percent off): The NM790 is a single-sided SSD that can post sequential read speeds of 7400 MB/s. The one-sided design means it stays cooler for longer, and this 1TB deal includes a heatsink. It's a great budget alternative to the also single-sided Samsung 990 Pro (see below).

• Sabrent Rocket 2230 for $150 (15 percent off): The Sabrent Rocket 2230 is a thumbnail-sized NVMe card that we found to be perfect for the M.2 slot on a Steam Deck. Thanks to this deal, you can save a lot by buying a lower-end Steam Deck and upgrading it with one of these.

• Samsung Fit Plus for $23 (34 percent off): The Fit Plus is our favorite thumb drive, and it's not close. Running on USB 3.1 with transfer speeds between 300 and 400 MB/s, it even comes with a keychain hook. The current deal takes 34 percent off an already cheap product.

• Samsung 870 EVO for $76 (24 percent off): The 870 EVO is a great budget choice for general users, who are likely to get a speed boost on any PC activity once it's installed. At 560 MB/s of maximum reading speed, it's not for hardcore gamers, but everyday users should see real benefits.

• Samsung 990 Pro for $150 (29 percent off): The whole Samsung Pro line of SSDs is excellent for gamers, with PS5s in particular seeming to run much faster with one installed. The 990 Pro can reach read speeds of up to 1,400 KB/s — and yes, that's kilobytes, not megabytes.

• Samsung 9100 Pro for $220 (31 percent off): Samsung's first NVMe SSD dropped earlier this year, and currently, they're still a bit faster than most people can use. However, if you want to get a jump on the next console generation with 14,800 MB/s sequential reading speed, this deal is your opportunity.

• Kingston Fury Renegade for $420 (33 percent off): Although it sounds like a Jamaican kung fu movie we'd watch the hell out of, the Kingston Fury Renegade is actually a 5th-gen NVMe SSD that can reach hardcore read speeds of up to 14,800 MB/s. It's expensive, but Prime Day discounts knock off 33 percent.

• Corsair MP600 Pro LPX 2 TB for $160 (20 percent off): Earlier this year, we named the Corsair MP600 Pro LPX as the top SSD for PS5, partly due to its affordability. It's even more affordable now — and the low price even includes a heatsink.

• Acer FA100 1TB for $51 (15 percent off): The Acer FA100 isn't the fastest SSD, but it is at least competitive, and may be one of the cheapest ways to harness the considerable power of NVMe 3.0. Only the 1TB version is marked down for Prime Day.

• Samsung T7 for $114 (39 percent off): The T7 spent a long time as our reigning champion portable SSD, and it's still an amazing deal — being technically outdated means record-low prices on hardware that's more than fast enough for a Steam Deck or Switch.

• Samsung T9 for $170 (43 percent off): We once named the Samsung T7 as our favorite portable SSD, but the T9 handily outdoes it, nearly doubling data transfer speeds. It's marked down 43 percent from now until the end of Prime Day on the 11th.

• SanDisk 1TB Extreme for $78 (40 percent off): SanDisk designed the Extreme for portability, and it shows — this is an almost indestructible SSD you can keep in just about any bag or pocket. It's also reasonably fast, though it only works with USB-C. This 1TB deal knocks off 40 percent of the price.

• SanDisk 2TB Extreme for $120 (43 percent off): The 2TB version of the SanDisk Extreme is on sale for 43 percent off, saving you $90 on 1,050 MB/s of read speed.

• SanDisk 4TB Extreme PRO for $270 (32 percent off): This deal doubles not only the storage space of the 2TB Extreme above, but also its read and write speeds, with each hovering around 2000 MB/s. It's a very cheap way to get your hands on a USB 3.2 Gen 2x2 drive.

• Crucial X9 Pro 1TB for $75 (17 percent off): As a Gen 2 USB drive, the Crucial X9 Pro loses out to some newer competitors on speed — but it's much cheaper, and far more compatible with everyday personal computers. The 1TB model is on sale at 17 percent off its normal price.

• Crucial X9 Pro 2TB for $120 (33 percent off): The Crucial X9 Pro with 2TB storage space is marked down 33 percent for Prime Day.

• Crucial X10 1TB for $82 (24 percent off): The Crucial X10 is a portable SSD for power users, only working at full strength on devices that support the latest version of USB 3.2. If that's what your build needs, you're not likely to see it much cheaper than this.

• Crucial X10 2TB for $135 (18 percent off): A 2TB version of the X10 is almost 20 percent off right now.

• Crucial X10 Pro 2TB for $150 (28 percent off): The Crucial X10 Pro is perfect for a fairly small range of users. If your PC build currently works with USB 3.2 Gen 2x2 but isn't yet handling USB4 or Thunderbolt, you won't find a faster portable SSD for your needs.

• Kingston XS1000 for $80 (15 percent off): We named the Kingston XS1000 the second-best portable SSD in our current roundup, so it's great to see it going for 15 percent off today. It's almost as fast as the Crucial X9 Pro, just not quite as tough.

• ADATA SE920 for $142 (5 percent off): The piddly 5 percent off is disappointing, but there's nothing disappointing about the ADATA SE920 itself. This is the ideal model for anyone regularly making huge downloads. The SE920's maximum read speed of 3,800 MB/s would be impressive for a full-size SSD, but it's fully portable, weighing less than half a pound.

• Garmese 1TB Portable SSD for $64 (20 percent off): This portable SSD uses USB3.2 to achieve read speeds of around 1000 MB/s, which is very impressive for a device not much larger than a flash drive. While it downloads fast, it's not fantastic for transferring multiple files at a time.

• Lexar Professional Silver Plus for $38 (48 percent off): Our tests showed this to be the fastest microSD card on the market, beating out the whole Samsung line. Not only is it fast enough to download and upload 4K files without trying your patience, it's also waterproof, cheap and squeezes in both USB-A and USB-C ports.

• Lexar E-Series for $31 (15 percent off): While the Silver Plus beats it out, the Lexar E-Series remains more than fast enough for 4K video, and is sufficiently rugged to fit in your adventure camera. This deal includes a five-pack of microSD cards, working out to about six dollars per 64GB of storage.

• Samsung Pro Plus for $17 (35 percent off): The Samsung Pro Plus is a great microSD card for most needs, so if it's cheaper than the Lexar option, go for it. We've found that it's particularly good in handheld game systems. Just make sure to get the version rated for 180 MB/s, nothing less (it should say on the package).

• SanDisk Ultra 256GB microSDXC for $17 (35 percent off): If you're still rocking the Switch 1 (thanks, Target) and want a cheap storage expander, this deal on a SanDisk 256GB microSD card is for you. It's going for $17 right now, far less than most of the games you're likely to store on it.

• Samsung Evo Select for $22 (27 percent off): This one's by far the best option if you're after a cheap microSD card — we've seen it on sale for less than $25 more than once. It's a bit too slow for cameras, but fine for any kind of undemanding passive storage.

• Seagate Portable for $65 (19 percent off): All the Seagate hard drives we've used are refreshingly good at combining thin, light hardware with consistent speeds, and the Portable is no exception. At 4TB, this is a great deal on an external HDD with no tradeoffs.

• Seagate Game Drive for $76 (16 percent off): Seagate's Game Drive is a prime choice for adding extra space to a PS5 or Xbox Series X. Formerly overpriced, it's now dropped down to $90 for 2 TB, and that's before Prime Day makes it even cheaper.

• WD My Passport for $140 (24 percent off): The Western Digital My Passport line is ancient by computer hardware standards, but it's been updated as far as USB 3.0 and 3.1, and remains one of the cheaper options for a 6 TB hard drive. This version includes automatic backup software.

• WD Elements for $130 (26 percent off): The Elements HDD from Western Digital has gotten consistently positive feedback from our staff over the years, and as an older model, it's now wildly cheap for 6 TB of storage. It's compatible with both PC and Mac out of the box.

• WD_BLACK P10 Game Drive for $155 (18 percent off): We're big fans of the WD_BLACK SSD, and the gaming-focused external P10 is a worthy companion. It comes with 6 TB of storage for your PC, PS5, or Xbox gaming library.

• UnionSine 500GB External Hard Drive for $27 (19 percent off): UnionSine's HDD is fast and USB3 compatible. Despite how thin and light it is, we've found it remarkably hard to damage. 500GB may be a bit tight with the size of files these days, but at this price, you could just buy two of them.
