Thanks a lot Don! That is one fast notebook hard drive! I found my hard 
drive about a third to a half slower even though it is a (older) 7200rpm 
hard drive.

As a matter of comparison, I have a T43 with a Hitachi travelstar 
7200rpm 60GB 7k60(model number HTS726060M9AT00), 1.86 Pentium M 1G ram.  
Now due to the infamous PATA to SATA bridge my hard drive shows up as 
SATA drive and has to undergo some fiddling to get to work. A 
consequence is that I have this perennial fear that I'm not squeezing 
the maximum out of this drive. Another consequence is that not all hard 
drive is compatible with my T43
http://thinkwiki.org/wiki/Problem_with_non-ThinkPad_hard_disks
So I'm posting my test result to serve two purpose:
1) To compare others out there with T43(p) and same hard drive to see if 
anyone get better number and if so what I can do to improve performance.
2) To see whether anyone has a different hard drive working under T43 
that has better performance.
So thank in advance for all the else with their results, here's the 
numbers:
root@laptop:# hdparm -tT /dev/sda

/dev/sda:
 Timing cached reads:   3640 MB in  2.00 seconds = 1820.00 MB/sec
 Timing buffered disk reads:  114 MB in  3.02 seconds =  37.75 MB/sec
