I only say that because the Western Digital Raptors, are only 37gb in size.
If you are comparing to 80gb drives, to 37's, well, thats obvious. Though
they are by far the fastest ones out right now. I was just saying, two 40gb
ide drives vs two 37gb sata raptors, theres no contest. :)   Western Digital
is supposedly going to release a new sata drive this fall (Nov/Dec), that is
around 80gb in size, and the same performance as the 37gb Raptor. I just
havent seen it yet. Im not an expert on raid, but raid 0 is the fastest,
splitting data across two drives (no mirroring or duplexing), raid 1 is
mirroring (basically a full copy on another disk), raid 5 (mirroriing with
parity?) The main increase would come from the SATA interface, being that it
is faster than IDE, and currently also faster in seek times to the 15k SCSI
drives. Not to mention a WHOLE lot cheaper. Someone correct me if im wrong.
