UDMA 6 on the ICH5R?

What's the deal with this? I have 2 Maxtor SATA/150 HD's on SATA1 and
SATA2, no raid or promise. The P4C800ed BIOS lists UDMA-5. Does this
MOBO not support UDMA-6? or is it that Intel has never ratified UDMA 6
on their southbridges?

Is this lack of UDMA 6 support effecting my drive speed? or do I not
need to worry about this?

The ICH5 don't support ATA/133 (UDMA6). You can also notice that most
harddrivemanufactureres are still sticking tiwh ATA/100. For a long
while only MAxtor had support for ATA/133, but now also Samsung have.
But it dosn't matter. The fastest P-ATA-drives on the market now are
infact ATA/100 -- like the Hitachi 7K250 and 7K400... ATA/133 is just
most for marketing, but the drives ain't fast enough to have any
real-world performance-gain from it. So, you should matter and stick
with the ICH5-controller instead of using the boards Promise
ATA/133-ccontroller. My experience is less trouble with the
chipset-integreted controller.

P4C800-E Deluxe have a separate Promise ATA133-controller
on the board.
