I'm looking into buying a network attached storage drive for my Mac,
which has FireWire 800, 400, and USB 2, in addition to gigabit
ethernet. I plan on attaching the device to the FW800 port.

I'll be using the drive as a back up for my Mac, but I'll also be
storing photos and videos with file sizes larger than 4GB. I'll be
accessing the image data with a Windows OS and Linux OS computer, but
that's a secondary use.

I've been scanning /. for information on file systems, and there's no
clear consensus when dealing with a hodgepodge of OSes. I haven't had
good luck on summaries searching Google, probably because I don't know
enough to do a good search.

From Ars Technica, I get the impression that Mac OS Extended (Case
Sensitive, Journaled) is a good choice. ZFS gets good marks, but that
is not an option on Disk Utility.

Anybody have any thoughts or useful search suggestions?

the file system that most nas devices use internally is not normally
exposed to clients and it's probably ext3. clients connect to it via
smb and that will limit you if you use a mac. some nas devices also
support afp, which for mac clients, is a lot better (assuming the
implementation is decent).

another option is just get an external drive for your mac and share it
to other computers on your network, rather than a dedicated nas box.

NAS stands for Network Attached Storage. Such devices typically connect
directly to an Ethernet router or switch. The file system used by the
NAS will likely be a Windows or Windows-friendly file system, and there
may be corresponding limitations. I've never been fond of the idea of
storing Mac files on foreign (non-HFS) file systems unless absolutely
neccessary.

If you want to attach it to a Firewire port, NAS isn't what you want. In
that case, you probably want to get a Drobo (http://drobo.com) and use
Mac OS X file sharing (AFP & Samba) to allow other compuetrs to access
it. I have this setup here at home and it's great. Let me know if you
have any questions.

For SATA, Firewire, or USB use the native format of whatever it is
connected to. That would be Journaled HFS+ for Mac OS X. SMB sharing
on the Mac would provide access to Windows and Linux.

A NAS will have its own private format presented as a network
filesystem. I strongly recommend a NAS with AFP, SMB, and extended
attribute support.

Look for performance tests when choosing a drive because consumer RAID
often performs poorly.

Fastest to slowest disk connections:
SATA
FW800
Gigabit Ethernet with Jumbo frames
FW400
Gigabit Ethernet
USB 2
USB 1
WiFi


Write speeds on my disks:
'dd count=1000 bs=262144 if=/dev/zero of=/Volumes/XXXX/test'

Drobo FW800, 4x 1TB WD Green : 25 MB/sec
via OS X Server AFP, Gigabit w/Jumbo Frames: 25 MB/sec
LaCie 5big NAS, RAID 5, AFP, Gigabit w/Jumbo Frames : 12 MB/sec
Early Mac Pro SATA, 2x 1TB WD Green, Striped: 160 MB/sec
Mac Mini Server, Striped : 145 MB/sec
via OS X Server AFP, Gigabit w/Jumbo Frames: 60 MB/sec

Okay, guys, many thanks for the help. Looks like I'll just keep it on
my Mac as a FireWire drive with HFS+ and let other computers access it
through the Mac.
