Good product quality and inspiring strength (see in duration) Reconstruction of RAID 5 takes about ten hours The product comes with an application that manages several such products and for sending e-mails to alert (by cons must be launched the app it seems) No problems with a Mac, the triple connectivity is perfect and you can chain Firewire 800. I would have liked a version 5 drives with hot spare disk (it can be done but with 3 discs at once therefore less volume but LaCie offers the same box with larger hard drives)
