ATA RAID for Email server?

I have a Windows 2000 server with dual PIII 1.13Ghz w/ 512 cache on each and 1GB RAM. I have a PERC 3 RAID controller with two 36GB SCSI drives. It handles my web serving and database access.

I am getting a Linux box (1Ghz PIII and 512MB RAM) to run the Email server and DNS processes. I am a very small company, and I need to keep costs low. To do so, I am considering going with an ATA Raid solution from IWill. I know that this in no way compares to SCSI RAID, but my question is, will it be sufficient for a hosting company that is just starting out?

Please keep in mind that right now I am very small, and the server will just be handling Email and DNS. Will the ATA RAID suffice?

Thank you.
