file system
 

which file system is better suited for ssd? ext2, ext4, btrfs? and why?

ext2 has no journaling . this is a plus for ssd

A quick search on the web for which filesystem best for ssd ext btrfs provides a lot of information on the subject, more than a few answers here will. These include:

I do not think that Google knows better than the inhabitants of the forum

Well you seem to have done some research on your own by opining that ext2 has no journaling and that you feel it is a positive case for ssd storage.

I think what hydrurga's point here is that one can search the web for information and do some research as opposed to just asking an open-ended question.

I have a different opinion in that I do not feel it is of real consequence and that it's how much you load the disk as well as how much you plan to read-write-erase. The rewrites per storage location on these disks are far improved over the years and the disks themselves perform load leveling to distribute the data. However if you constantly fill and empty the disk, or fill it mostly and leave only a fraction of space remaining, then there's little room to have either a software file system, or hardware assist perform the load leveling.

Google and other web search engines provide a route to the views of a far greater number of people than there are active on this forum. For a question like this, where you want to see different general opinions on costs and benefits, and where these will have undoubtedly been discussed on the web, it is a useful resource. For a far wider picture of the issue, you can combine the information from your web searches with the opinions offered on here.

why?
Is data on an SSD less important and/or less likely to become corrupted?

there is no my opinion and no research done by me. I asked on the forum because I think that there are people who have experience and knowledge of using Linux. Linux is a server and large amounts of data. Who else but you should know everything about file systems?

the topic is not meant to settle disputes but to get the opinion of everyone.

Modern SSDs are built with read-write cycles expected and lifetimes of things like 5 to 10 years of worsed case expected.

ok))))

In most cases I say stick to your distro's default filesystem. It'll be what that distro supports and tests the best, and any reasonably modern distro will have sensible defaults for SSDs. Usually it's ext4, xfs, or btrfs; the first two are very mature and solid and personally I'd be quite happy to use btrfs too nowadays.
