Whoohoo --- major HDD upgrade just went down!!! Got my Samsung 160gb SATAs from Newegg, and a 4-port SATA RAID card from eBay (not 3ware

).
Running:
60gb WD POS for a boot drive
160's in RAID 1 for data
a pair of ATA-133 30gb Maxtors in RAID 0 on a separate controller for scratch 12gb IBM IDE 'cause it didn't have anywhere else to be just then
I'm running the SATA controller in 64/66 PCI mode, so it's fairly quick even in RAID 1. With a fair bit of ECC/REG RAM and a big video card on top of things, I'm glad I got the larger 550w Enermax PSU.
