WD Red Internals
The WD Red comes in a standard 3.5" form factor and is emblazoned with the signature red branding. The bottom of the drive has the PCB with the components turned inward, facilitating thermal dissipation into the case of the drive.
Upon removal of the PCB, we note the thermal pad over the controller. This mates with a metal pad on the case of the PCB through the foam padding. The foam padding is utilized to negate vibration.
The Marvell controller dominates the center of the PCB, with the 64MB cache module to the left. There is also a drive motor controller and the four pins that connect to the motor.
The WD Red features a standard 6Gb/s SATA port.
