SATA is the new standrad, UATA133 is the latest incarnation of the old IDE/ATA
standard. They are not interchangable without adapters[1]. As far as support
with your version of Linux, you may want to check out the SATA Chipset Linux
Support Status page[2]. Since your system is already SATA, it would probably
be best to buy a SATA drive instead of using either a UATA drive w/adapter or
a UATA drive w/a PCI->IDE card.

It sounds like you can use SATA in "legacy ATA mode" assuming your system's
BIOS supports this. Also, you *might* have UATA connectors on your
motherboard and could plug in a UATA drive directly w/o the PCI card.
