Well, I think so. A number of phones actually use that I am pretty sure. The kernel for android is pretty darn the same as desktop linux.

Pretty sure you could use it on a home or server. The tests you refer to may or may not favor your filesystem for your use.


Wonder why your link came up wrong and blocked by the way on my system.

Because it is wrong. There is an extra /http:// and I've seen that several times recently; don't know why.

Well there is not much information there and it isn't clear what out of that would convince you that F2FS was a good idea, generally (it still might be, I'm just not sure you see that from the linked article). In the AIO stress test, F2FS is slower than everything except BTRFS. In the Dbench test F2FS was fastest, but it would be rather optimistic to expect that to apply to anything other than a database access pattern, maybe even only the database access pattern used for the particular test.

With TIOT, it had once been fastest but with a slightly more recent kernel it has become slowest (although, TIOT often gives quite different looking results from other tests). This is not a good thing. In postmark F2FS was fastest.

If you were to try to summarise, I think you'd have to go for something like
  • The chances are that if you are running a mail server which is close to what Postmark does, probably F2FS is fastest, although there is evidence of something close to 'cheating' (gettiing better results than are theoretically possible) here.
  • Database accesses can be particularly sensitive to minor changes (ie, what applies to Mysql doesn't necessarily apply to postgresql), but there is at least a possibility that F2FS would be good.
  • For more general use there is little evidence that F2FS would be anything other than a way of slowing things down.
So, really, you would like better evidence, unless you have one of the exact patterns on which F2FS has been shown to do well.

I'm going to try and piggyback on this old thread, even though my aims in considering using f2fs on an SSD are slightly different from those of the OP. See, I have this old SSD I'm using on my Void Linux system (currently has ext4 file system), a drive old enough to not support trim. Though the machine doesn't get used a whole lot, I'm looking into ways to extend the disk's life. One thing I thought of is using a file system designed to reduce read/write cycles and disk access, of which f2fs is an example. So, could I expect using a file system like f2fs on this system to have any notable effect on the life of this drive? Input will be appreciated.

NOTE: searching I've done so far into putting f2fs on an SSD reveals mostly discussions centering on what sort of accelerated drive access that file system might provide. That's a secondary concern for me: I'm much more interested in knowing whether using such a file system might appreciably increase the lifetime of an SSD that does not support use of such maintenance utilities as fstrim.
