FIle system for maximum write speed of very large files

[Nordlöw]

We are building a data collection system with two striped disks.

If we want to maximize the write performance for very large (tens of
gigabytes) what file system should we use?:
ext2,3,4 reiser, xfs, jfs, btrfs?

I believe we don't want nor need journalized write operations.

Thanks in advance,
Nordlöw

If I was looking to do fast-as-possible writes in that size range, I'd
use a raw disk (no filesystem on it at all), with some sort of database
on another disk saying what went where (it's actually a pretty standard
technique; google for googlefs to find one particular implementation of
the idea).
