The drive's enclosure is typical Micron. Formed from both sheet and cast aluminum alloy, the 2.5"x 7mm enclosure is grey in color with an industrial style textured finish.

With the drive disassembled, we see there is a plastic spacer that separates the two halves of the drive's enclosure. We also note a blue thermal pad located on the cast half of the enclosure. The thermal pad contacts the drive's controller and DRAM package.

The M500DC and M510DC both employ the same PCB. The only difference between the two is the flash node. This half of the green PCB houses the drive's 8-channel Marvell 88SS9187 controller, one of the drives two 512MB DRAM packages, one of the drives five flash packages and all thirteen of the drives tantalum capacitors. In contrast to the M500DC, the M510DC employs 128GB less over provisioning with a RAW total capacity of 640GB for the 480GB model.
