Best SSD deal

$639.99 Save $250   Get Deal

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.

Why we like it

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.

Best travel-friendly SSD deal

$549.99 Save $170   Get Deal

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 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.
