Best file system for SSD?
Does anyone know of any good references on what the best filesystem is (ext3, xfs, etc, etc) for an SSD (mainly, which filesystem has the fewest writes)
Also I was looking around for references on how to relocate/remove high-write areas like /var/log somewhere else (like /dev/null) to prevent unnecesary writes.
Thanks
Re: Best file system for SSD?
I'm using ext3 but setting the noatime option, I've also put a bunch of things in tmpfs to reduce writes. I'd prefer non-journaled and have had good experiences with XFS, I was using ext3 on an SD card but it had problems with resume and I found XFS didn't.

Meant to say, here's fstab entries for three high write offenders:
Code:
none /var/log tmpfs defaults,size=10M 0 0
none /tmp tmpfs defaults,size=100M 0 0
none /var/tmp tmpfs defaults,size=20M 0 0
You might want to look at what Firefox does too - it accesses the disk a lot because of the sqlite dbases its using.

I don't think that you have to take care about it so much. SSD works fine with ext4 for me.
Do you know how much read/write operations can it perform? Their amount is HUGE.
Re: Best file system for SSD?
Its not just the write cycles, with things like the Aspire One because SSD reads very quickly but writes very slowly it can become a bottleneck and its very effective to tune the amount of disk writes.

do you sync your logs or just purge them on reboot?
Re: Best file system for SSD?
I would prob say EXT3 but to me imo I'd use EXT3 on any device... I love that format the best, seems to work out the best overall for me so.

Well, when setting up my netbook, I used ext2, no swap space and am thinking about tmpfs for Firefox's cache.

@lavinog: I Purge them on this one, rsync them on my main (non-testing system) along with my Firefox profile which _really_ benefits from tmpfs on the Acer Aspire One.

I've done it, using rsync to save it before exit and it makes a big difference - no stuttering on the Aspire One.
