I use the d2 from the early versions it several years ago. The final model (v2) is still without fan (yes!) And is shaped heat-sink (heat sink). It gives him a look more "pro" than older models and guarantee a longer life ... Transfer rates advertised are real! It reaches the same 105MB / s for FW800 ... It is still faster Serial ATA. There is also possibility of the racks via an adapter for the brand.
Very fast and quiet, large disk is perfect for Pro Tools LE. For HD, the Glyph may be more suitable.
You can buy eyes closed!
