NEED TO REPLACE RAID1 EVERYTHING

I have an i865GBF M/B, and have been [trying to] running Seagate 120Gb SATAs in a RAID1.  The drive connectors
for power and data are weaker than the wires that conect them.  I hate the resync after manual reboot EVERY morning!! I am looking for an affordable SCSI alternative, and am asking for the forums help.  Unfortunately, price IS a
consideration.  This is not quite off-topic, as it IS actually a RAID problem.....

thanks for reading.
