Opening the WD Blue (removing four Phillips screws), we see the PCB. At the solder side, there are no chips.

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 controller used by the WD Blue 1,000 GiB is the Marvell 88SS1074, presented in Figure 6.

There are two DDR3-1866 memory chips, with 512 MiB capacity each, model Micron MT41K512M8RG-107, that work as a data buffer.

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