Or that is just because laptops usually have slower disks.
10-15 years ago or so an ordinary laptop would have an 4200 rpm IDE
disk, while a desktop would spin at 5400 rpm or even 7200 rpm.
And servers would have scsi disks at 10000 or 15000 rpms.

But now - a large amount of laptops have SSDs instead. And some are
faster some are slower.

So dividing into laptop/desktop for general disk access optimisation
seems strange to me.

If you run your tests on an external drive and compare the output
from both laptops and desktops - is there a difference?
