Right now I am using 4 SSD's ( 120GB) , but want to move to something more reliable / more storage. Right now I am running 20 Windows 7 x64 machines , 1 webserver and my firewall. The IO wait is around 0.2% idle and 3-5% is the highest I have seen yet. I am considering buying a RAID card or two but am curious if a SAN would be better for my situation. I need around 1TB of storage so was thinking 8x1TB RAID 10 would work quite well but am new to SAN so have no idea if that would be something I should look at before making any purchases .
