We are in the process of purchasing a new server for our department and I'm doing the specs. I am the point where I want to get the best performance but maintain price.
In my research, everybody seems to take RAID 10 over RAID 5 for its capability of both performance AND reliability. I am interested to get feedback from people that have worked with SATA and SCSI drives in RAID configurations.
My question is: IF you had choice between
a) Three 73GB SCSI 10K RPM in RAID 5 config, or
b) Four 80GB SATA 10K RPM in RAID 10
What would you get? They both spec-out very close in price. Is the SCSI performance that much better to for-go the RAID 10 with SATAs?
