nf7-s + SATA hdd only giving ATA100 (UDMA5) performance

[Grant Holman]

Hi,

I've using a NF7-S with a Maxtor DiamondPro Plus 9 SATA drive (latest BIOS and Silion Image drivers)

Sisoft Sandra benchmarks it at eqivalent to a 5400rpm ATA100 and reports its only running at UDMA5 (hence poor performance). Can't see anyway of adjusting this in either BIOS or Windows XP up to full ATA150 (UDMA6?) speed.

The maxtor drives have problems with the sata controller and the sata bios was modded to reduce the max setting. ATA150 is a nonsense with a PCI based controller anyway. That's why the latest southbridges integrate the SATA function.

ATA133 is UDMA6

Doesn't really matter as mechanically 7200rpm drives can't give you that anyway - if you are lucky you will get just over 100 burst. Oh, & Sandra is suspect - try HDTach.
