A portable storage device can make a world of difference to intensive processing tasks, from running massive video games — which feels like all of them these days — to core operating system functions. A solid-state drive (SSD) gives your hard drive more bandwidth than it comes with by default, making huge chunks of data easier to digest and keeping your device from running too hot. This October Prime Day, we've rounded up the best deals on SSDs, portable SSDs and microSD cards. Not only are these some of the best products in the field, but their prices are lower than they're likely to be for some time thanks to Amazon Prime Day.
Best October Prime Day SSD deals
Amazon Crucial T710 2TB Gen5 NVMe SSD $230 (36 percent off) $230 Fifth-generation SSDs are still a little faster than most people need, but with software only getting bigger, use cases are likely to grow. To get an early jump on future speeds, check out the Crucial T710 with 2TB of storage, a super-fast SSD that reads at up to 14,500MB/s. This deal doesn't include a heatsink, but it does come with free hardware encryption. $230 (36 percent off) at Amazon
Crucial T500 1TB for $89 (38 percent off): We named the Crucial T500 one of the best SSDs for PS5 and still stand by that rating. This 1TB model can hit read speeds of 7,300MB/s, more than enough for optimal performance per Sony's specs. You can even install it at home with no tools more complicated than a screwdriver.
Crucial X10 4TB Portable SSD for $240 (39 percent off): The Crucial X9 is our current favorite portable SSD, but the X10 is a step beyond. Based on USB 3.2, it's compatible with a wide range of devices, and reaches reading speeds of 2,100MB/s — all in an extremely portable pocket-sized case.

Samsung 990 Evo Plus 1TB for $70 (33 percent off): This is an incredible deal on an internal SSD from a reliable brand. All capacities of the Samsung 990 Evo Plus are currently on sale, but even the 1TB option can visibly boost your performance with top read speeds of 7,250MB/s. There's no heatsink, but nickel plating on the controller reduces both heat output and energy use.
Samsung Fit Plus 256GB for $23 (30 percent off): The Samsung Fit Plus isn't just the best thumb drive on the market right now — it's one of the best SSDs, period. This deal gets you 256GB of storage and read speeds of 400MB/s for almost unfathomably cheap. It's also built to resist water, extreme temperatures, magnets and even radiation.
Kingston SX1000 1TB High Performance for $89 (23 percent off): If you can't swing a Crucial X9 or X10 right now, Kingston offers a much more affordable alternative. The SX1000 can handle both PC backups and gaming storage with ease, nearly matching the X9 in our speed tests. It's also easy to carry around, though keep a tight grip as it's not officially rated for any drop height.
SanDisk 2TB Extreme Portable SSD for $148 (29 percent off): The SanDisk Extreme line of portable SSDs provides a great middle ground in both price and performance. Read speeds of 1,050MB/s are enough for transferring most files you'll encounter day-to-day. Its external design holds up too, with a large carabiner loop, IP65 waterproofing and dustproofing and drop protection as high as three meters.

Seagate Storage Expansion Card 2TB for $220 (39 percent off): This SeaGate SSD is specifically for expanding storage on the Xbox Series X and S, and it's designed to meet Xbox specs exactly. You'll get exactly the same performance booting a game from this card as you would from internal Xbox storage, which makes data management infinitely easier.
