Hi all,
pardon for jumping into this thread, but ..

from the linux point-of-view I would avoid NTFS as much as possible.
It's proprietary M$ technology, it's undocumented (only M$ has the NTFS
documentation), so it is reverse engineered (so there might be bugs or
subtle problems in it's Linux implementation). With NTFS I had also
under Windoze some uncomfortable situations.
If possible you should use a native Linux filesystem, one of the
ext[234] is preferable, or XFS. I would also avoid JFS and Reiserfs.
Hans Reiser is prisoned because of murdering his wife, so Reiser is in a
kind of unmaintained state, additionally the kernel developers have
refused to integrate reiser4 into the vanilla kernel. The argumentation
was, that the coding style of the reiser4 patches is bad. With reiser3 I
had some very uncomfortable situations, where data loss nearly happened.
JFS (from IBM), hmm, I have no own experience with it, but you can find
reports which indicate bad performance and/or stability issues. I would
not trust a fs with such a reputation. BTRFS is in a kind of beta state.
If performance is an issue for you, you should avoid all FUSE based
filesystems, because the FUSE design comprises more overhead in form of
context switches (which is bad on such a weak hardware as the Alixes
are), but it makes development easier.
My 2 cents
