You might also want to try enabling ultradma, as well. Hdparm says messing with
that is dangerous, but, honestly, I never saw any kind of harm doing hdparm -X

Check 'hdparm --help' for the -X (case) option. This shall bring you to the
best possible transfer speed for the drive.
Some older drives have firmware that claim to support a particular
(U)DMA mode, but don't properly implement it. Actually enabling support
for that mode can have catastrophic consequences. Though, as you point
out, that is mostly not a problem, especially in modern drives.

Yes, I should have stressed the 'modern' issue. Most drives I tested are
as new as 2001 up to now. Thanks...
