The installation of a 2.5 HDD is very easy. The housing is made of plastic, however, although the board sits very firmly in it and the case appears to me thus nice and quiet. USB, FireWire and FireWire 800 interfaces are available. Unfortunately, only once Firewire800 and not twice. Why the daisy chain that will be invisible.
Otherwise can be set with tools like hdparm various parameters such as acoustic management or power management.
