Packaging and Contents
The drive uses the M.2 2280 form factor, which means it is 22 mm wide and 80 mm long.
Like most M.2 NVMe SSDs, the ADATA SX8200 Pro uses a PCI-Express 3.0 x4 interface.
The included heatsink comes with sticky tape preattached.
Just peel off the protective film and stick it on the SSD. Note how the white sticky tape and screw cutout match the PCB layout.
You will find the SSD controller and four flash chips on the PCB. Two DDR3 DRAM chips are also present to provide the SSD controller with operating memory for mapping tables.
The Silicon Motion SM2263ENG is a new controller with improved performance.
The four flash chips are Micron 64-layer 3D TLC NAND; they have been rebranded as "ADATA". Each chip has a capacity of 256 GB. For cost optimization, ADATA buys silicon wafers from Micron, cuts them up, tests and bins the chips, and puts them inside their own packaging.
Two Nanya 512 MB DDR3 chips provide fast DRAM storage for the controller to store the mapping tables in.
