I bet that the cache and buffer management of linux will definitely mask out any drive's internal cache. For one thing, the operating system has much more information about the way resources are used, and can manage them better than simply doing predictive readaheads or delaying writbacks. > drive setup (the maximum under ATA), it might not make a big > difference in performance, certainly not enough to justify the > huge price difference of a SCSI drive. This is so true, and was my bottom line in my previous past posts. Not only do you have the more expensive drive, you have to get an expensive controller as well, as motherboards don't usually come with SCSI onboard. _ Philippine Linux Users Group.
