I've been using it for years since the first versions came out. The latest model (v2) has still no fan (good!) and it has a heat-sink like design. It gives it a more professional look than previous models and ensures a longer operating life... The published transfer rates are REAL! It's even possible to reach 105 Mb/s with FW800... It's even faster in Serial ATA mode. It's also possible to mount them in a rack with an optional mounting kit.
Very fast and quiet, it's the perfect hard disk for Pro Tools LE. For an HD, the Glyph models might be better.
You can buy it with closed eyes!
