[solved] filesystem for fastest startup on ssd

Hey,
there's a lot to read on this topic but i'd still like to hear your opinion.

I'm running a little music server with mpd on a system with an Intel X-25M G1 SSD and i want it to boot as fast as possible. Since i shut down the system suspend-to-ram is no option for me. Neither is suspend-to-disk.
The music files are on NTFS partitions and there's generally little to no write access to the SSD, mostly just read access.

So I'm wondering what filesystem (and which IO scheduler) i should choose for fastest bootup. I guess i need fast read performance with small files and quick mounting?
So far I can't decide between Reiser4, JFS, ext4 and ext2. The latter should have best performance but what happens at an improper shutdown?

Any suggestions or experiences?
Thanks.

EXT-4 should be the best. If you have a UPS, add "barrier=0" in the kernel mount options.

If you have time for testing, you could try BtrFS, the new FS, which has an SSD mount option.

No UPS here. Still ext4? If so, which scheduler should i choose to work best with ext4 and an SSD with writecache like the Intel SSD?
Does the Arch Install Manager support installing on BtrFS yet?

The default one is the best, there have been great changes lately,(especially on the CFQ due to BFS tongue).

Okay thanks, ext4 it is.


Edit: ext4 works fine and fast at startup. On my laptop, JFS is faster while on my server ext4 boots faster. I don't know why or how but that's how it is.
