Heh, yes. I see the irony in that :-) But this is pretty much as the source as you can get.

Is there even such a thing as optimal chunk size?

64K should be fine:

Okay, even if this is almost 5 years old, it is still applicable?

The disks I have are 4k sectors. Is there anything special I need to think about or is this handled automagicly these days? (I run a pretty fresh distro)
