There was the theoretical side - ie coming up with a way of defining
perfection which then allows measuring against. For example you have
going up to a 128K block size but without knowing the theoretical best we
don't know if that

'Theoretical best' seems too vaguely defined,
It seems like a good thing for someone to tackle as part of a master's

with compression it's always some trade-off and compromise
Which you can put in

Hello Tomasz
Have you considered per-file/per-directory selection of raid level?
Sounds great, I haven't thought about it before.
Do you or someone else know what the current state of development is?
Is someone working

If you are more interested in the theoretical side then looking into
compression would be interesting. ie how close to the theoretical best
compression are we. Various filesystems like btrfs and NTFS make all
sorts of compromises

Maybe this happens already: Might a similar effect be automatically

I haven't done any extensive testing, only streaming writes, and the
heuristic just batched writes by a given threshold before switching to
another mirror. Load balancing was done without any logic that would
look at actual IO load

One thing I would like see it automatic backup copies of data. For
example if you are only using 10% of the total space then make an
