I've got an Asus P5W64 WS Pro with 3 Sata 2 disks. The sata chipset is an ICH7

http://es.asus.com/products4.aspx?l1=3&amp...amp;modelmenu=2

 

I've installed JAS 10.4.8 + patch to 10.4.9 + ich7 patch ...

 

Seems that my sata disk are very slow

Xbench give me these results:

43,48 sequencial

33,56 random

 

How can I optimize this ? My SATA disks are setup as AHCI in the bios.

I'm not sure that the proper ich7 driver is loaded

 

# ioreg | grep ICH

# ioreg | grep PIIX
