I meant to say when It gets very little lag when even it gets taxed heavily. A lot of times, I will have a web browser open with up to 25 tabs open, then iTunes, as well as IRC, IM, FTP (for uploading) Copying large files, and a bunch of other stuff

I will be using Disk Utility's SoftRAID Function. That way I get enhanced throughput. I decided to throw the 1TB Drive I fixed into an external enclosure. That way it's portable and I can backup the server. Also, I know it will boot, and I have the files already backed up in real time, it won't be an issue if I do a RAID-0 even if I have a catastrophical crash that is unrecoverable (which is normal when a RAID-0 goes down)
