Excerpt: I've been using a USB 2.0 device plugged into the limited number of USB ports on the iMac... it's been OK... I'm going through one of those paranoia stages and spotted this drive that will back itself up with RAID and connects via Thunderbolt... seemed like a great solution... I'm THRILLED with it! Seems a little strange that something so simple can make me so happy and confident but this device is fantastic!
Pros: Fast Connectivity, Raid Backup, Small, Versatile
