The casing is metal. The top part is black with Seagate’ logo and labelling, the base is plain metal. However, unlike other drives which either is secured with a security Torx or a Phillips head screws, the drive’s plate is secure by clips. The only way to remove it is to pry it open, carefully.

All the NANDs and controllers are on one side of the PCB. The controller has a thermal pad, but is also aided with a heatsink on the casing positioned to make contact.

The drive uses Toshiba THS8TEG8DDJBA8C 8X 32GB NAND and 2x 128MB Micron D9LHP DDR2 chips for buffering, followed by Link-A-Media LM87800 controller.

The drive comes with B660 firmware, and there’s no firmware update from Seagate for this drive at the time of writing. Its an unused drive, so I ran endurance testing long enough. The issue however is that Seagate’s 600 Series’ Health Status is not being read out, at the very least not on my setup.
