The Drive

The drive conforms to the dimensions set forth by the 2.5" form factor. It is made of metal, which improves its durability. Please note that the drive is thinner than normal 2.5" SSDs. Its height of 7 mm makes it a perfect match for the latest Ultrabooks.

SSD Interface Connector

Like most recent SSDs, the Samsung 840 Pro uses the SATA 6 Gbps interface. It is compatible with any older SATA standard, but will, in such a case, work at reduced performance.
