I am looking to purchase a new server for a client. The current server is a RAID5 with the OS and data all on one partiiton of that RAID5. I know that is not very efficeint because Windows has to deal with all that data on one partition, and have learned instead that you should at least always partition your RAID and create a seperate parition for your heavy moving data and one for the OS. If this is not accurate, please correct me.
My question before I purchase a new server is this...
Should I just get a RAID5 and create 2 partitions, as discussed above. One for the OS and one for the data files. Or would it be better to have a dedicated RAID5 for the heavy data and then have a seperate RAID1 or 5 for just the OS? It would all be on the same RAID controller, but would be 2 seperate RAIDs. Would this be worth the costs? Would I really see any benefit to this?
Also, SCSI seems to be going out and SATA is coming in. Should I go with the SATA RAID?
