Is this use of slightly based upon disk failure modes? That is, when
disks fail do they tend to get isolated areas of badness compared to

the disk.
The field data I have says that complete disk failures are the
exception.
It's the same here. In our 100 laptop population in the last 2 years,
we had 2 dead drives and 10 or so with I/O errors.
BTW, this feature will be very welcome on my laptop! I can't wait :-)
I, too, would love having two copies of my important data on my
laptop drive. Laptop drives are small enough as they are, there's no
point in storing the OS, tmp and swap files twice as well.
So if ditto-data blocks aren't hard to implement, they would be
welcome. Otherwise there's still the mirror-split-your-drive approach.
Wout.
