SATA or SAS for file share storage
Another straw poll just to get an idea of what's out there and working well :)
For VMs, Exchange and SQL SAS is a no-brainer, the faster the better so we'll probably be getting 15k drives there.
For user file shares, department areas etc I'm thinking SATA makes sense from a cost per GB point of view but will 7200rpm drives give enough performance if people are hitting them simultaneously for mandatory profiles, roaming profiles for staff plus the usual file IO? At the moment the profiles and data for staff are on 10k RAID5 SCSI disks and the student profiles and shared data are on another server, SCSI again.
What have you got on your SAN for data and does it perform well?
