best disk RAID config for XP/Sonar
I just got in the additional drives for the new XP system I just built and am debating which RAID config to set up to best suit Sonar/Video work.
I will have a total of 4 250GB Sata drives in the system. The MB has a hardware RAID controller so I won't be using the OS. I'm debating between setting all 4 drives up as a RAID 5 stripe giving me a total of 750GB raw space and only using 1 drive for parity. This stripe would include the OS, applications, and data all in one stripe.
The other option is to do a RAID 1 (mirror) stripe on two 250GB disks for the OS, apps and data backup and a RAID 0 stripe (concat) on two additional 250GB disks for keeping audio and video on for best performance. I would still have a total of 750GB of raw disk space but now if I lost one of the data drives I would also lose the data...whereas, if I lost one drive in the RAID 5 stripe I would still maintain the data but performance would be horrific until I replaced the drive.
I'm thinking I would rather have full data protection (RAID 5) as long as the performance would be acceptable.
Anybody have any experience or opinions on the subject?
