Physical Features:

While not the smallest portable hard drive in Silicon-Power's product lineup, the Diamond D05 is still very compact and lightweight. Measuring 124.8 x 75.8 x 13.6 mm and weighing a mere 155g, the drive easily fits in a pocket, purse or laptop bag. 

The top of the Diamond D05 has what Silicon-Power calls a scratch resistant, metallic grain surface which looks much better in person that it does in my photos. The rest of the drive is constructed out of lightweight, black plastic. While the top edges have a glossy finish, the bottom has a rougher, matte finish that makes it a little easier to hang onto when moving it around. Unlike the top, the plastic parts of the drive are not scratch resistant.

The Diamond D05's SuperSpeed USB 3.0 interface is located along the right hand side of the drive.  This connector not only transfers data, but provides power for the drive. While you can't see it in these pictures, there is an LED located on the end of the Diamond D05. This LED lights up blue when the drive is powered on and and will flash to show when data is being transferred.

I wasn't able to crack the Diamond D05 open. However, using CrystalDiskInfo, I was able to see what hard drive was in the enclosure. Looking at the screenshot below, you can see that Silicon Power has used Samsung's Spinpoint M8 (HN-M750MBB) hard drive. This drive features a SATA 3.0Gb/s interface, 8MB cache and a 5400 RPM rotation speed.
