This is a really good, simple breakdown of some filesystems that are available to Linux users.
For what it's worth, i use XFS on my server and i have typically used EXT4 on my Linux installations. I'm currently using btrfs as a bit of an experiment, and while it's been reliable and the Timeshift works great with it, i've had some lag at times. Some articles i've read or seen say something about the way the btrfs works can result in apparent lag in some programs. I don't know if my experience is due to btrfs, but i used EXT4 for 4 years on a single install in the past, and i don't recall feeling this lag. So on my next installation (soon), i'm going back to EXT4 to see what happens.
I just really liked that video, and figured i'd share.
I think just stick to stability. I am aware that zfs probably is more at home on FreeBSD.
You need to be aware that there are other systems and one which I don't like, which Knoppix has used since version 8.0 I believe, is ReiserFS (written by a German developer who murdered his wife). You can not use any other FS when installing Knoppix - infuriating. I also lost a lot of data when playing with SuSE Linux 9.3 Professional, and I remember one of the Editors of the now defunct Amiga Format magazine stated in an intro that he wished he had listened to the ExtFS gods instead of using ReiserFS which also lost him a lot of data too.
If an FS is proven, longstanding like the Ext ones, then don't mess with anything else IMHO.
