Here I have

/dev/hda: 26.91 MB/sec
/dev/hda1: 26.90 MB/sec (Windows FAT32)
/dev/hda7: 17.89 MB/sec (Linux EXT3)

Could you give me a reason how this is possible?

a reason for what ? the fact that the notebook performs faster than the
desktop while slower on I/O ?

No, a reason why the partition with Linux (ReiserFS or Ext3) is always slower
than the Windows partition?

Easy: Drives don't have the same speed on all tracks. The platters are
built-up from zones with different recording densities: zones near the
center of the platters have a lower recording density and hence a lower
datarate (less bits/second pass under the head). Zones at the outer
diameter have a higher recording density and a higher datarate.


So it has definitely nothing to do with filesystem? I also thought about physical reasons because I don't think the hdparm depends on filesystems...
