The drive conforms to the dimensions set forth by the 2.5" form factor. It is made out of plastic and is only 7 mm thick, which ensures it will fit everywhere.
Western Digital's WD Red SSD uses the SATA 6 Gbps interface. It is compatible with any older SATA standard, but will in such a case work at reduced performance.
On the rather compact PCB, you'll find four NAND flash chips (two on each side), the controller, and a DRAM chip.
The Marvell 88SS1074 6 Gb/s flash controller supports four flash channels. It was released in 2014 and is built using 28 nm fab technology.
The four TLC flash chips are made by SanDisk in collaboration with Toshiba. They are built using 64 layers on a 15 nanometer 3D NAND production process.
A single Nanya DDR3-1600 DRAM chip provides 512 MB of fast DRAM storage for the controller to store the mapping tables.
