"Agree with CNET"3.0 starson by LFCRulesOK
Pros: Reliable USB, warm feeling of having a backup
Cons: Unreliable Firewire on Mac, one year warrenty, support forums locked to owners only
Summary: Have got to agree with CNET's review of the V2. I'm using a Mac using Leopard, and have had unreliable connection to Firewire. I could make it hang at will, by simply loading it up with work, using Handbrake, Mac The Ripper, or even regular Mac Finder Copy.
However, USB has been rock solid. Ripped and converted many of my DVD's on USB without error. Speed is relatively ok, but it is USB. I got in touch with support via email, and after many a test, I am waiting for a warrenty replacement.
I would say check out my thread on the Drobo owners forum for more info, but I can't as it's locked to owners only. You can check out my progress and others on AVForums.com if it helps others who may have problems who don't go to the official forums.
