It is possible to have the both of the worlds with hybrid filesystems.
Btrfs could be one eventually, and there's a rudimentary zfs port
for Linux in the works. No idea which will make the cut first.

Of course you could export a hybrid zfs pool as an iSCSI target,
but this runs contrary to my philosophy (achieving high peformance
and availability economically, by using lots of cheap, high-efficiency 
hardware -- the current sweet spot is currently Supermicro/Atom, but 
I'm hoping for ARM).
