Raid 5 or Raid 1 for file server and exchange server
Posted on 2004-10-04
I have already purchased a raid 5 server with 4 SCSI drives on a perc4-dc card. I was planning on using this server for running exchange on. Our mail storage size is around 8 gigs. So its not very much. Would I see any performance gain at all if I was to go with a raid 1 setup instead for my exchange server? I have been told with small databases and mostly read and very little write to the hard disk that raid 5 is the best option. How big does my database file need to reach before it become beneficial to go with raid 1.
Also, I need a file server. Mostly I see people using raid 5 for file servers. Would I be better off using raid 1 or raid 5 for this file server. This is for a new company with only a few employees. This server will also double as a domain controller. I was thinking that if I was better off using raid 1 in the exchange server I could then use the raid 5 server for my file server.
