I know, second SSD question in as many days. This was prompted by a G+ discussion I was following. I had seen the opinion that it was best to avoid journalling file systems to reduce writes to the SSD (the answers to my earlier question come the the consensus that modern SSD's have a long enough life span to make such considerations moot). The discussion I was following pointed out that the older file systems don't natively recognize TRIM. It was stated that btrfs is the best choice in that it both recognizes TRIM and is not journalling. I was under the impression btrfs was a journalling FS. What are the opinions of the forum?

That is a good question so far my only concern is about the the life time write times and i didn't thought the FS is involved too. Looks like in a few more years SSDs will be as popular as the HDDs are now.

Performance-wise JFS is the best:

However, it doesn't support TRIM, so if you want that, you have to use ext4. Btrfs also supports TRIM, but they don't have a fsck util yet. They will soon tho, they say February 14, just a few days from now:

Btrfs. It actually has an ssd mount option.

Good reading here!

True, but I wouldn't recommend btrfs until they have a working fsck.

Edit: I missed H_TeXMeX_H's post, if they come up with fsck I may be thinking about a change on one of my systems to give it a try.
