500GB 2.5" SATA III Internal Laptop Hard Drive – 5400 RPM 7mm Slim – Open Box

Need some extra storage for your laptop?

This 500GB SATA III drive is a solid pick.

It's a slim 7mm form factor, so it fits most modern laptops, and it spins at 5400 RPM with an 8MB cache.

This one's an open box item, meaning it's in excellent, like-new condition—it just might not have the original retail packaging.

It supports hot swap and runs at 6.0Gb/s.

No brand name on this one, but it's a reliable generic option if you're on a budget and just need to store files, music, or games.
