On this particular occasion, Silicon Power decided that a geometrical pattern reminiscent (loosely) of diamonds was a good choice.
Thus it was that the Diamond D01 came to be, complete with an USB 2.0 port (no 3.0, alas), an LED indicator, plug-and-play support (no need for external power adapters) and a sleep mode, for power saving.
The aluminum case is colored metallic black and scratch-resistant too.
