The best Prime Day SSD and external hard drive deals on Samsung, Crucial and more

Prime Day is a great time to pick up gear and upgrades you wouldn't normally think about. In case you've never used a solid-state drive (SSD) before, it's a class of add-ons that bolster a device's built-in storage. Not only will your phone, laptop or console be able to hold more data, but more of those files will be quickly accessible, which can vastly improve your speeds. If you have used an SSD before, you know what you're looking for — the best discounted drives on Amazon. We've curated a list below for your Prime Day shopping.

Best Prime Day SSD deals

• Crucial P310 1TB for $60 (20 percent off): This deal on the Crucial P310 is one of the best we've seen so far for a Gen 4 SSD. At the 1TB capacity, it reads up to 7,100MB per second for noticeably faster performance. Just be warned that the deal doesn't include a heatsink.

• 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 $210 (30 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.

• Sabrent Rocket 2230 for $150 (45 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 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.

Best Prime Day portable SSD deals

• 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.

• 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 X9 Pro 4TB $260 (10 percent off): If you're after the highest-capacity model of the Crucial X9 Pro, you can grab it for 10 percent off through the end of Prime Day.

• Crucial X10 1TB for $82 (41 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.
