mSATA SSDs easily fit in the palm of your hand, yet are available in capacities of 120GB, 128GB, 240GB 250GB, 500GB, even 1TB, often without any performance hit over using a 2.5" model. While newer laptops are shifting to the M.2 connector, mSATA slots are still found on previous generation motherboards and laptops. These SSDs are great for providing such systems with a fast, silent storage upgrade.
