Highpoint already make a 4 sata channel card, the rocketraid 1540
It comes with 4 sata cable and 4 rockethead (sata to ata-100)
DOH
For the drive, seagate have changed the page and they are now back to 1 year.......
sorry for the misconception
seagate info on ssata drives
But they would have been better than the solution from maxtor or WD because they are native sata and not ata-100 converted to sata. If you read the review on lostcircuit (don't have the link for it on hand), they did great.
And also, they do not quote anymore the service life. So it seems they have reduced their waranty on every drive they make (IDE)
By the way GMAT, i know you were joking, as i was too, because in most sig, most have IDE drives

Also GMAT, if you use an external card, not the chipset (like a promise card, which is a software raid card) it doesn't use that much cpu, but it might be because i use quantum hd.
