I am building a file server and need to protect data and also increase performance. We are currently using RAID 1 which is very slow, although it does protect against loss. What are your recommendations? Thanks.

RAID 10, RAID 5, RAID 6, etc. would all be faster than RAID1, and offer redundancy.

That has plenty of information :)  I'll summarize those 3 though.

RAID5: Minimum of 3 disks. Storage equal to ([Amount of disks] - 1) the disks. Fault tolerance of 1 disk.

RAID6: Minimum of 4 disks. Storage equal to ([Amount of disks] - 2) the disks. Fault tolerance of 2 disks.

RAID10: Minimum of 4 disks. Storage equal to half the total storage. Fault tolerance of 1 disk. Slight improvement in performance.

I didn't explain a whole lot I know; I suggest you read through ever level on that website (both single and nested), just so that you have a good understanding of what each level is. That's what I did, it won't take too much of your time.
