The drive has plug-and-play ease of set up. I purchased one for Time Machine backup of an iMac, and connected it as a network drive to an AirPort Extreme.
Worked well, the disk and fan are not too loud, but the device failed. The iMac cannot see the drive, although it is still recognized in the About this Mac/more info window. The LaCie website support is not helpful at all.
An external drive that cannot outlast the drive it is meant to backup is worth next to nothing.
