The interface on the drive end is an edge connector on the PCB, as opposed to the usual SATA cabling. As the name suggests, the slot is a conduit to the Serial ATA bus in the system. (Most mSATA drives relevant to upgraders measure about 1x2 inches.) mSATA drives fit into a special slot in a laptop's logic board or on a PC motherboard. The boiled-down essence of an SSD with the shell removed, an mSATA drive is a bare, rectangular circuit board. The first attempt was a new form factor called mini-SATA, or mSATA. Why not design around that? In the Beginning, There Was mSATA. So when mobile-device designers, challenged with slimming down laptops and tablets, reassessed this issue, the consensus was clear: The bulky 2.5-inch form factor, eventually, would have to go.Īt the core, an SSD is just a thin circuit board studded with flash-memory and controller chips. It's designed in that 2.5-inch size and shape to make the drive fit into those existing bays. The enclosure an SSD comes in has a lot of dead space inside. However, from an engineering point of view, SSDs didn't need to be that big. Over time, too, desktop PC chassis have evolved to gain their own bays and mounting points for 2.5-inch drives. You could mount them in a 3.5-inch drive bay using a simple bracket. (They could configure laptops with the choice of a hard drive or an SSD without any retooling.) Desktop PCs, meanwhile, could accommodate SSDs of this size with little fuss. SSD makers adopted this standard size to make SSDs compatible with existing laptop designs. (In actuality, the drives are about 2.75 inches wide.) These SSDs have the same dimensions that laptop-style hard drives do. The traditional SSD that you buy and install in a desktop PC, or in place of a hard drive in a laptop, uses what's known as the '2.5-inch drive' form factor.
