THE M550 256GB

Appearance-wise the casing of the M550 is identical to that of the M500 so nothing new here.

The model name, model number, serial number, barcodes, electrical requirements, model capacity, encryption key (PSID), firmware version and several certification icons are placed on a large sticker at the rear.

At the rear we see the typical SATA power and data connectors.

Crucial makes it very easy to open the casing but by doing so you're voiding the warranty.

The drive has a total of 16 NAND flash modules on both sides of the PCB.

On the opposite side we see the low-power DRAM module by Micron (512MB LPDDR3) and the Marvel 88SS9189 controller.
