OK, I did this test with the unmounted Tibook /dev/sda  
(target mode). So I executed the one-liners below on the
alubook. /dev/sda should be the hard disk on the tibook:

####################################################

# /sbin/hdparm -tT /dev/sda

/dev/sda:
 Timing cached reads:   1244 MB in  2.00 seconds = 620.49 MB/sec
 Timing buffered disk reads:   34 MB in  3.02 seconds =  11.24 MB/sec
[root@ 01:21:02]# /sbin/hdparm -tT /dev/sda

/dev/sda:
 Timing cached reads:   1232 MB in  2.00 seconds = 615.19 MB/sec
 Timing buffered disk reads:   34 MB in  3.04 seconds =  11.17 MB/sec
[root@ 01:21:20]# /sbin/hdparm -tT /dev/sda

/dev/sda:
 Timing cached reads:   1260 MB in  2.00 seconds = 628.93 MB/sec
 Timing buffered disk reads:   36 MB in  3.07 seconds =  11.72 MB/sec
[root@ 01:21:35]#

Looks good, doesn't it?

Thanks again

Best Regards
Wolfgang
