Does anyone here have experience with Lacie's Little Big Disk. It's a fanless external drive enclosure with two 2.5" drives in RAID 0 setup, with triple interfaces (USB 2.0, FW 400 & 800). I like the look and the spec so I was wondering if anyone here actually own one and try to get your opinions on it. I'm especially interested in the 320 GB, which features 2 160 Gig 5400 RPM drives, and the 200 GB, which features 2 100 Gig 7200 RPM drives. I'm torn because I want the capacity of the 320, but worry about giving up too much speed because of the 5400 RPM. Any advice or comment will be appreciated.
