[Bioclusters] Urgent advice on RAID design requested

[Angulo, David]

I disagree with you.  Look at http://www.bestbuybusiness.com/bbfb/en/US/adirect/bestbuy?cmd=catProductDetail&productID=BB10725830&operation=showDetails  This is RAID, so the mean time between failure will be extremely large.  This is extremely reliable.
