If so then the config you listed, Raid 1 for NOS and Raid 5 for your data would be best. If you don't need the redundancy, then RAID 0 will offer the best performance. However if you lose a hard drive you have to restore the array from backup. <BR /><BR />Ciao,<BR />Greg Fri, 15 Oct 2004 14:17:17 GMT Greg Carlson 2004-10-15T14:17:17Z https://community.hpe.com/t5/netservers/new-server-disk-advice/m-p/3401277#M7279 A bit of general advice please from the experts out there.<BR />We are thinking of a new server to run the CAD database etc. replacing an older LC2000 running NT4.<BR />What would you recommend as a 'belt and braces' approach to a good disk setup.<BR />OS on 2 x mirrored drives with the Data on Raid 5 array?<BR />Thanks in advance for any alternative advice offered.
