Introduction and Specifications
Today we’re going to be looking at a somewhat different type of drive from Samsung, the SM843 Pro Data Series SSD. The SM843 is essentially the same drive as the consumer-targeted 840 Pro SSD, but with a specialized firmware that’s optimized for mainstream, ready-heavy data center applications and more over-provisioning of the NAND. We’ve got the full specifications of the drive below, followed by some pics of the product and its internals.
As cool as the internals look, it’s the Samsung SM843 Pro Data Series SSD’s performance that is really attractive. You’ll get to see what we mean by that on the pages ahead...

Externally, the Samsung SM843 Pro Data Series SSD looks much like any other solid state drive that conforms to the common 2.5” form factor, but with a 7mm Z-Height. The drive has a basic metal enclosure, with a simple texture and a single decal listing model and serial number information.
