RAID 5 for the 12TB array , and a Dual 1 TB Mirror for Boot. I want my PORN fast and protected...
Caviar Blacks has the same issues unfortunately.
I've switched to Hitachi and Sammy's as well. The older Caviar drives didn't have this issue. This is WD wanting you to pay to do RAID. There are folks out there hacking the functionality back into the HD firmware to try and restore what WD ripped out.
Nothing wrong with the DROBO, just possibly the drive you linked to. I just wanted to warn you about issues with the WD drives doing RAID. Lots of folks found this out the Hard($$$) way.
