I am tired of watching fsck check my filesystem when my eeepc 901 shuts down abruptly due to a crash. I know that with a journaling filesystem, I won't have to wait for a check. However, I am well aware of the poor I/O performance of the SSD, so I can imagine using a journaling filesystem being even more frustrating, since there will be constant writes to the journal?

I will buy a new laptop without such a crummy ssd someday but, is there anything I can do now, on the software side of things?

    What are you on now? ext2/3 are older than ext4, and ext4 was made in the knowledge of ssds.

    You might also want to read Aligning filesystems to an SSD’s erase block size by Theodore Ts'o (one the men behind ext4). Feb 15 '11 at 1:28

  • @maaartinus This model has a 4gb master ssd, and a 16gb slave. The slave drive is much slower. shinyplastic.com/archives/…

There are log-structured file systems available, like LogFS and NilFS that may be more performant on your SSD, but I'm unsure of their stability.

  • Is one of these FS stable by 2018 ? Is F2FS a good choice ?

  • @SebMa: I'm not sure what happened with any of those fliesystems, but SSDs had their performance increase to the point where it doesn't really matter anymore.

try with ReiserFS - checking fs is very fast. This is my fs of choice - rock solid

  • But will it be constantly writing to the journal? This could be a problem since the ssd is so slow...

Another filesystem to try is btrFS. According to one of the main developers of ext3 and ext4, ext4 was actually intended more of a gateway between ext3 and btrFS (much like Microsoft's failed Windows ME transition from dos-based to NT-based). btrFS is still not at a "stable" release, but I hear it is very stable.

--EDIT-- By not "stable" but stable, I mean I don't know of any serious problems that would affect someone who uses a system normally. It's still considered a development version, but it's fairly polished.
