My only issue with the REVO is the PCI-E, which... while better, is a limitation. I suppose I could find a motherboard with like... 6-8 PCI-E 1x slots? But right now I think they're looking to do a RAID-0 across as many SSD's as possible. Data redundancy and capacity are pretty much a non-issue.
The previous build was across 7x Velociraptor drives
