This is an absolutely tiny solid state drive. Not in capacity terms - nope, it packs 500GB into that frame - but in build size. It’s tough to really get across just how wee the new Samsung 840 EVO mSATA drive is. Even when I tell you it measures some 5 x 3cm that hardly seems to do it justice. The fact is you’d probably miss the drive even once it’s embedded in a mini-ITX motherboard.
