WD Re 4TB Internals

The WD Re comes in a standard 3.5 form factor. The components on the bottom of the HDD PCB are faced inward to avoid damage, and also allow the components to shed heat into the case of the HDD.

Removing the PCB reveals the foam pad used to dampen vibration during use. We also observe the dual thermal pads used for the drive controller and motor controller on the base of the HDD.


The NANYA chip is a 64MB DDR2 component for caching. A controller to control the drive motor resides to the upper left, and a Marvell 88i9346-TFJ2 dual-core drive controller dominates the lower right of the PCB.

The small angled components marked SK1 and SK4 are multi-axis accelerometers that allow the drive to detect vibration and shock, and compensate accordingly. There is an additional sensor to the upper right of the PCB (out of view in this shot).

The Re version we are testing today features a 6Gb/s SATA connection, and there are also SAS versions available as we mentioned earlier.
