I'm using Intel SSD X25-M on my laptop, and I always hear that is not a
good idea use journal on SSD (it decrease the life time).
I ask Intel about this, but I don't receive any answer.
So, I would like to know if is possible disable Journal on EXT4.
It is possible to create an ext4 file system without a journal. It
would mean that unclean shutdowns would require a full fsck, which on
a freshly created file system on an SSD isn't _that_ bad. Depending
on how full/fragmented your filesystem happens to be, it will probably
be under 10 seconds.
That being said, though, it shouldn't be necessary to avoid using a
journal on the Intel SSD. Intel says that laptop will last at least 5
years with 10GB worth of writes per day...
Woww! Thank you so much Theodore and Eric!
I will keep using journal on my SSD X25-M.
