At the component side, we see wight flash memory chips, two DDR3 memory chips that work as a buffer, and the controller chip. Notice the SanDisk logo at the corner; the WD Blue 1,000 GiB is actually an updated version of the SanDisk X400 SSD.

The flash memory chips are from SanDisk, and unfortunately we couldn’t find the official chip specs.
