The SanDisk Extreme 1TB portable solid state drive is down to $119.99 at Costco. That's not just a great deal at Costco but one of the best deals we've ever seen. The same drive is currently $160 at retailers like Amazon and B&H, and it's going for $170 at Best Buy. The drive has gone on sale in the past, but we've never seen it go this low before. You will need to be a Costco member to check out with it, though.

The SanDisk Extreme is a very portable solid state drive. With 1TB of space you can keep all your music and other media real close by. Since it's an SSD, you don't have to worry about the same moving parts you'd find on a portable hard drive, so it's a lot more durable and can bounce around in your pack without you worrying about it. You'll also be able to transfer data to it rather quickly with speeds up to 550 MB/s.

The SSD works with both PC and Mac. It's also backed by a three-year warranty from SanDisk.
