I am sorry, but I do not give my computer components freedom of choice. :) I just do not understand how a 5400 RPM UDMA 33 drive can beat a 7200 RPM UDMA 133 drive by 33% on sequential output blocks. > Does the drive support tagged queueing?

Another question, I see that in the archives that enabling IDE Prefetch was not good. Has this changed? I currently have it turned off in the BIOS. Hmm, I see that Søren mentions it should be kept on: http://groups.google.com/groups?hl=en&lr=lang_en&ie=UTF-8&selm=200201091654.g09GsG703561_freebsd.dk%40ns.sol.net OTOH, he says that the ATA driver automatically turns it on. BTW, would there happen to be a preferred BIOS setup page for FreeBSD? I have already scanned through the docs.
