Best FS to come for SSD storage: Ext4, BtrFS or NilFS?

[kozaki]

Hey, here are some sources (English, French) about the upcoming file systems optimized for SSD storage and perfs. Unfortunately i have very poor relevant information beside those few links

* Linus Torvald being very positive about his new Intel SSD. : "what that Intel SSD does so well is random reads and writes. (...) The whole thing just rocks. You can put that disk in a machine, and suddenly you almost don't even need to care whether things were in your page cache or not. Firefox starts up pretty much as snappily in the cold-cache case as it does hot-cache. You can do package installation and big untars, and you don't even notice it, because your desktop doesn't get laggy or anything.” Pitifully Linus does not even care to say the file system and options he uses even if some comments ask for it)

* "Benchmarking Linux, Round 2" at Linux-Kongress 2006 : Pure FS (no SSD) benchmark (see intro). 23 GB tar & 300 MB tar on Linux 2.6.17 ext2/ext3/reiserfs/reiser4/XFS/JFS, FreeBSD 6.1 UFS async, NetBSD AMD64 UFS, Windows 2003 Server, Vista (build 5472.5), Longhorn Server (build 5484), SchilliX 0.5.2 (OpenSolaris) ZFS Time goes from 18 to 157 minutes!
* PERFORMANCE OF FILESYSTEMS COMPARED : Reiser4, Reiser3, Ext4 (extents/default), Ext3, Ext2, XFS, JFS, NTFS(3g), VFAT (just for the record: for more contextual info about the author, one has to see this: The Linux Kernel Saboteurs of Reiser4

IMHO, SSD is desktop/notebook future storage solution as well as yet poorly implemented in present netbooks due to unadapted FS.
- SSD + FS may well enable everyone's systems to bypass the actual HDD's limitations (e.g. today CPUs and RAM are 20 faster today than 10 years ago while HDDs are ~3 times faster).
- Open source filesystems development looks like it's going quite faster than proprietary. Yet it's not ready. Can you imagine the impact on both the market and the average Ms/M Joe of a Moblin (mobile linux) OS + toolkit Clutter (OpenGL) + super fast low-consumption SSD with adequate FS ?
Please what do you know about about the next FS for SSD ?

EDIT: added Linux-Kongress 2006 multi-OS and FS benchmarks (PDF available here).

I would probably go with ext4. And yeah SSD's do rock if the reviews on newegg.com are any indication of how good it is. I have never read more glowing reviews than those reviewing SSD's. Everyone is absolutely in love with them. They say response time is near instant, and like getting a whole new computer. they also said that putting an SSD on an older pc isn't worth it. But on newer ones, it is simply the best upgrade you can do.

Over 100 reviews here http://www.newegg.com/Product/ProductReview.aspx?Item=N82E16820167005

I plan to try NILFS, as it also have easy snapshots.
So for e very consistent backup that can also be done in bacgroun di can make a script to set a snapshot, then take a backup of that.

The ability to brows history of a file with the (planned) history browser seem nice too, as i do lot of radical edits in CAD, documentation and plans while developing things.


About the speed of drives, CPU and RAM:
I remember i years ago got a notble boost on my 486DX2 machine when i installed stacker to compress the drive; it could uncompress data significantly faster than a raw read.

As seek time on SSD:s are extremely low, it will mostly be the data transfer that takes time, so compressed storage will increase the speed boost of SSD:s (as long as the CPU can keep up)
