The Samsung 840 EVO is an mSATA SSD that is the first to hit the 1TB capacity point. Though it has a compact mSATA form factor, roughly a quarter of the size of a standard 2.5” SSD, it packs the performance punch of its larger siblings. Ultra-thin laptops have been limited in their storage capacity up until now. Taking advantage of Samsung’s advances in flash memory, the 840 EVO mSATA SSD will take portable computing capacity and speeds in ultra-thin computers that was previously unattainable. To get to the 1TB capacity point, Samsung uses a total of four flash memory packages, each having 16 dense layers of 128Gb TLC chips.
