RAID 1 for File server

I am getting ready to order a new file server for a network of 100 users. I was wandering if any of you have setup a file server with a simple RAID 1 mirror, and if so di it perfrom well? I know that I could configure either a RAID 0+1 or a RAID 10; however, that would require more dirves and higher cost. I am not looking for blazing speed perfromance; howerver, I don't want someone waiting 10 minutes to pull a 20-30 MB file from the server either. BTW, I plan on using the new Western Digital Enterprise SATA drives with 16MB cache.

There is very little speed difference between RAID 1 and a single hard drive. You should not see a slow-down.

But bear in mind that Raid 1 is not a substitute for doing a daily backup, whether to tape or perhaps another HD. The RAID will provide resilience against a HD failure, but you still need regular backups against a problem which could corrupt BOTH hard drives.
Consider a routine like daily backups to tape on a weekly cycle, combined with weekly backups on a monthly cycle, monthly backups on an annual cycle.

I do have a backup plan, I am actually using a Exabyte 1.6 terabyte (compressed) backup unit with a 10 tape carousel. I am also in the process of creating a disater recovery plan. I just wanted your thoughts on a Files server with a Enterprise SATA RAID 1 array.

I recommend a RAID5 setup. It's not as good as the nested setups you mentioned but you get performance and fault tolerance.
Summary: I've been thinking about how to configure this the whole of last night. I have a server with 3x 200 GB Hard Drive. I also have 2 different 500 GB Hard Drive and 1 Fantom 500 GB External Hard Drive. No...
Summary: Given that you don't provide much information about the capacity of the server I will throw some ideas at what could be considered a cheap/economy file server and assuming you are not going rackmount....
Summary: I assume you're planning on getting an ide raid controller card because the kind of software raid you can implement with XP doesn't include raid 1. Your two 80gig drives may work but it's a big maybe....
