Just as a by the way, "libata" refers to the native SATA drivers (the
ones that show your drive as a SCSI device). The legacy PATA drivers
are most often refered to by their location in the kernel source tree:
drivers/ide/.
If both drivers detect and enable cache flushes for the drive's
on-board write cache (allowing it to be used), you should see no
difference in performance. At least as far as the driver is concerned.
I suppose it is possible that some chipsets are slower in legacy mode,
however.
