Buying hard drives

[Simon Haddon]

Ok,

The question to ask is why are my stats so low compared to the other 
hdparm stats.

I have a AMD K6II/300 with 192 Megs of ram. The disk in question is 
almost the same as Saul's.  In fact the only difference is that mine is 
20Gigs instead of 30.

I have also noticed that the dmesg is reporting that the IDE driver is 
assuming a 33MHz bus speed.  Is this correct.  Should it be a 66MHz 
maybe.
