I will use it with a IBM 75GXP disk. Well, if you ask me the HPT370 is about the best ATA chip you can get currently, it has the lowest overhead of them all. I can get slightly faster write transfer rate (we are talking controller to disk buffer here) on the Promise ATA100 controller, but they are both very close to whats possible... However stay clear of CMD ATA chips they suck bigtime even the new ones... So you only really need to have a board with extra ATA channels on it (be it HPT or Promise) if you need the extra connections it gives you (remember that for best performance you would only put one disk on each channel). -Søren To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
