Of course uptime is a concern, but it needs to be put into perspective. Let's assume that without RAID, the hard drive in use fails every 3 years and causes 24 hours of downtime with good backups. That's a loss of .09% uptime over 3 years. If the server makes $100,000/year (and the same amount every day), that's a loss of $273 over 3 years. However, my host wants $105/month for a second 15k hard drive and RAID controller card. The cost of that over 3 years is $3,780. Plus I like to keep things simple and RAID is another layer to learn, install, and maintain. Plus RAID isn't foolproof: http://hardware.slashdot.org/article.pl?sid=3D08/10/21/2126252&from=3Drss http://blogs.zdnet.com/storage/?p=3D162 Any opinions on Barcelona vs. Harpertown or 10k vs. 15k? - Grant
