Physical Features:

The Diamond D20 is one of the smallest portable hard drives to come through the 'Labs. Measuring 116.5 x 78 x 10.5 mm and weighing a mere 135g, the drive easily fits in a purse, laptop bag or even a pocket. 

The top of the Diamond D20 is made out of aluminum and is covered by a white, carbon-like texture that is designed to resist both scratches and fingerprints. The bottom and sides of the drive are covered by a lightweight, black plastic. The matte finish resists finger prints fairly well, but is not nearly as scratch resistant as the top.

The Diamond D20's SuperSpeed USB 3.0 interface is located along the bottom edge of the drive.  This connector not only transfers data, but provides power for the drive. Its hard to see in the picture, but there is a small LED located to the left of the USB 3.0 interface that lights up blue when the drive is powered on and will flash to show when data is being transferred.

I wasn't able to crack the Diamond D20 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 Toshiba's MQ01ABF series (MQ01ABF050) hard drive. This slim 7mm drive features a SATA 3.0Gb/s interface, 8MB cache and a 5400 RPM rotation speed.
