Iogear 40GB FIREWIRE+USB 2.0 HD ( GHD125C40 )

Rating:
Summary: can't get unwired
Review: Small form factor, rugged anodized aluminum case, light-weight. Almost everything you could ask for. The combo (usb 2.0/firewire) version REQUIRES the power adapter to be plugged in at all times. This is the only down side. If you don't need firewire compatibility consider the "USB 2.0 only" version for hassle free use.
