Hi,
I've just moved my IDE disks around, taking out an old disk and moving my new 6.4GB disk from hdd to hda.
With this move I saw in improvement (hdparm -t) from 3 to 8.4 (!) MB/second... Now I wonder what kind of bug in the Linux I/O subsystem could hold performance back _that_ badly. Of course both benchmarks were done on a completely unloaded IDE chip/PCI bus...
cheers,
