If I understand what you're here and previously, even though I get
9.5MB/sec no matter how I set all the hdparm switches, some of the
settings will deliver the same throughput at a lower CPU overhead?
That would be interesting to measure, but what sort of test would do the
job? Copying a huge huge file to /dev/null? I'd need to make a large file.
I have 256MB ram and 512MB swap (hey - what else to do with a 27GB drive?
;-).
