tuning the hard disk

["adwint pandora be" <adwint pandora be>]

Dears,

Dear fellow Red Hat addicts,
 
Yesterday, there was a nice thread on this list about "hdparm".

I checked it out: hdparm -Tt /dev/hda

It reports a speed of roughly 58 MB/S, without even changing any settings!

Would this mean the kernel, by default, optimizes the hard disk's parameters nowadays?  I can hardly imagine that this speed may be increased further on.

Since there are some rather intimidating warnings in the man, I don't thrust fooling around with it.

I would very much appreciate reading about other list members' experiences.
