I have an Asus A8V-Deluxe here with a VIA chipset, and using 250G WD 7200rpm SATA drives, and I get 56M/s, while with 120G WD drives on an intel ICH5R SATA controlelr I get 30M/s. I have no PATA drives other than a dvd-burner so I can't test the speed of that. Both using 2.6.11. The A8V is running a 64bit enabled kernel but 32bit user space, while the intel is just a normal P4 HT running 32bit. Remember that if the system is busy doing other things, it will affect your speed too. > optimusprime:/home/john# hdparm -t /dev/hda > > /dev/hda: > Timing buffered disk reads: 140 MB in 3.01 seconds = 46.55 MB/sec > > Both hard drives are Western Digital 7200RPM.

I never found an open source driver for the promise on the A8V yet, so I haven't tried it. Len Sorensen -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
