Which file system do you use and why?

Would this recent thread answer your question?

I mostly use EXT4. If I use an older box then JFS.

I use the Search-Engine Filesytem personally.

I see what you did there.

ext4 in all cases, myself.

ext2 on the /boot partition (no use for a journaled filesystem there), ext4 on all others.

Thanks, kikinovak. That's a clever way to configure your system.

I did googled for info before posting this question. It's not merely about knowing the pros and cons of each file systems... sometimes, I get more by asking folks with a wealth of experience

cheers

I usually use ext4 for all my partition (except those shared with Windows, of course), but out of curiosity and because of better performance in benchmarks on SSDs I tried JFS for my laptop. So far I have seen no downsides with that decision, but due to hardware limitation I can't see performance enhancements either.

Would ext2 be a better option for SSDs since it does less rw due to the lack of journalling support?

Hi,

Current SSD with new style controllers do not have issues with read/write like older designs. Plus the use of MLC does provide long term usage on new SSD at a lower cost to users.

Maybe this link will help: http://www.linuxquestions.org/questi...ml#post4585376

The SSDWiki can be resourceful.

Plus Arch SSD is another good resource.

Hope this helps.

To onebuck - Thanks for that information!

I haven't personally dove into SSD's yet, and your links have cleared up a few things I wondered about. Cheers!

There's another reason why I use ext2 on the /boot partition. I've been a GRUB user for a few years (legacy GRUB, not GRUB2), and this bootloader didn't play well with ext4 for some time. I don't use it anymore, since LILO does very well what it's supposed to do, but I've kept the habit. Plus, having a small /boot partition (30 to 100 MB) forces me to clean up an eventual mess of kernels, but that's a different story.

In fact, it would be counter-productive, since ext2 does not have support for the TRIM command, which helps the SSD to keep being fast and with wear-levelling.
I have no problem at all with wearout on my machines, my oldest SSD, a 40GB Intel device I used for about 3 years now, has about 3TB (currently not in use, I can't tell the exact values) written to it and reports lifetime indicator of 97%, so there are still some years to go with that device.
This is what the SSD in my main machine reports

Code:

  9 Power_On_Hours_and_Msec 0x0032   085   085   000    Old_age   Always       -       13164h+12m+59.350s
231 SSD_Life_Left           0x0013   100   100   010    Pre-fail  Always       -       0
241 Lifetime_Writes_GiB     0x0032   000   000   000    Old_age   Always       -       2866

As you can see, after 13000+ hours and 2.8TB written to it it still reports 100% life left.
