If you have a company with approximately 1000 users, 1 file server with 3 30GB drives using SCSI, what RAID configuration would be best and why?

In general, RAID 5.

All things equal, it's the most cost effective solution. The checksum is spread across all drives, instead of wasting the entire third hard drive as the check...

Also, when you lose one of the drives, the other two can always rebuild the lost data [so all RAID configs are better than plain striping].

5 gives a pretty good read/write performance ratio, too.

Mirroring would waste one of the drives, as it must always be done in pairs.

Your question doesn't give enough information to provide a hardware recommendation for a RAID setup. No where you you specify what the file server is for, how much data is supposed to be stored, How sensitive/important that data is, how much of data generated by users is added or deleted from the file server on a hourly, daily [or even by minute] basis. How many of the 1000 users actually access the file server, so on and so on.

Please provide more information.
