Thanks to the global memory crisis known as “RAMageddon,” prices on memory products like internal drives, external SSDs, and high-capacity flash storage have continued to climb. It’s been a relentless up, up, and up trajectory as AI demand squeezes consumer supply.

That makes finding genuine discounts during Prime Big Deal Days — Amazon’s 48-hour fall savings event that kicks off today and runs through Oct. 7 — all the more crucial.

High-speed NVMe drives, rugged external SSDs, microSD cards, and HDDs are Prime Day staples that matter more than ever amid RAMageddon. We did some digging and found the best October Prime Day deals in the solid-state and hard drive categories right now. If you’ve been waiting to expand your PC build, give your PS5 some breathing room, or secure your off-site backups, now is the time to take advantage of these offers from top-tier brands like Samsung, Sandisk, and more.

Pocket-sized, ridiculously fast, and virtually indestructible, the Sandisk 1TB Extreme Portable SSD is engineered for harsh travel conditions that would destroy standard desktop drives. It nearly doubles the speed of previous generations, so you can back up thousands of photos in less than a minute, while offering full weather resistance to rain and spills, and hardware encryption to keep your private documents locked down tighter than a vault. Now $209.99 for October Prime Day (normally $299.99), it’s never been cheaper before.

Why we like it

The Samsung 990 Pro delivers top-tier sequential speeds up to 7,450 MB/s, effectively maxing out what a PCIe 4.0 slot can process. That translates directly to faster boot times, near-instant game loading on PC or PS5, and smooth handling of large 4K video renders. It also runs more power-efficiently than its predecessor, so it stays stable under heavy continuous workloads. With a solid five-year warranty and a huge price drop, it’s one of the best value-for-money storage upgrades you can buy right now.

$549.99
Save $170

Why we like it

The Samsung T7 is built for life on the move. Weighing under two ounces and barely larger than a credit card, it slips into a pocket or backpack pouch without taking up space in your carry-on. Its solid aluminum unibody design handles the bumps of travel with ease, featuring shock resistance that withstands drops from up to 6 feet. With transfer speeds of up to 1,050 MB/s, you can offload massive 4K travel footage, photo backups, or offline media libraries in seconds. You can even plug it directly into an iPhone 15 Pro (or newer) to record high-res video straight to the drive while on location.
