Its very recommended to have only one disk per IDE/ATA channel since it can only deal with one request to one device at the time. > Drives are both Seagate 7200rpm 40Gb ATA100 and the controller supports > ATA100 also.

I have a very similar setup with a vinum raid, using 4 drives on 2 Promise ATA100 (the cheapest one) controllers. They work flawless. Just check the hardware notes on freebsd.org. There are several IDE/ATA controllers that are supported under 4.8-STABLE. > Solutions must be cheap i.e under 50 UKP as the wife will kill me for > spending any more ;-) > > Cheers all cheers, tom
