@odditory, the idea was to have parking lot storage of maybe 10 drives using 3 TB disks on 6Gbps ports of an ARC-1880IX-12 and use the last two ports for a RAID-0 windows 7 virtual machine for dealing with PAR2 archives and RARs. But since Newegg lists two flavors of 3 TB Deskstar I didn't know which one was considered "safe" for an array. Hitachi's website wasn't much help either because their model number doesn't match the Newegg model. Amazon has them for a few dollars cheaper but also uses a different model number than Hitachi.
