ADATA XPG SX8000 Overview
Taking a first look at the XPG SX8000 it comes in an M.2 package so it is not that big at all. M.2 drives are great as they connect directly to your motherboard and don’t take up any additional space in your system. This is a 2280 drive meaning that it is 80 mm long. On the front of the drive we have a sticker that lets us know that we do indeed have the XPG SX8000 256GB drive.
Towards the end of the drive you’ll find the controller, which is the Silicon Motion SM2260. This is an 8-channel controller which has four 8Gbps lanes and eight NAND channels. This controller is used by quite a lot of SSD manufactures. Now we have the original 256 GB version of the drive, but according to the ADATA website there is a new version that has an aluminum heatsink that goes over the controller. The controller on our version however does have a thin layer of copper over it.
On each side of the drive you’ll find Nanya cache chips, the 256 GB version of the drive have 256 MB of DRAM cache.
Finally on to the NAND chips, there are two on the back of the drive as well as two on the front. These are labeled ADATA they are actually Intel / Micron-made chips. They are 3D MLC NAND.
