Looks like I may finally be getting a box so I can migrate from SQL 2K to 2008R2! Now, my sysadmin wants to get a 1u box and build a SAN on the backend for all of the data (for other server data as well). I know typically you want to have RAID 5 with hot swappable drives for better uptime, but logistically, is there any reason NOT to go with a SAN for all of the backend data?
