Summary: Great delivery by Best Buy. Out of box followed instructions but 1 disk was apparently being rebuilt. When rebuilt the system did not recognise the drive when the raid software was installed. The system then incurred a 30% cpu overhead from the software. The Ram disk install may have been to blame but after several attempts on 2 PC's I had to rebulid both as the widows recover did not fully restore the system.
Cons: Does not install or work! Corrupted 2 PCs completely
