WD Xe 10k Internals
The Xe comes in the standard 15mm 2.5-inch form factor.
The dense foam pads help protect the PCB from vibration, and the white thermal pads allow the controller components to shed heat into the drive housing.
The upper left of the PCB holds two DRAM packages that total 32MB. A Winbond motor controller is placed on the right side of the PCB, and the secondary processor is near the bottom edge.
The Marvell i1248-C2 controller is the primary controller for the drive.
The SAS 6Gb/s connection provides the SCSI command set and dual-port functionality.
