What Filesystem to use for Linux Ubuntu? [closed]

I am new to Linux, coming from Windows background. What Filesystem should I use? I read that Ext3 is default still? Ext4 is unstable at times? true?

Also is there any performance different between the 2? So bottom line is what to use?

I'm pretty sure ext3 is the default, but I've used ext4 for years with no troubles at all. ext4 is made to increase storage size and increase performance of the filesystem. Overall, I've had really good success with it.

This will tell you all you need to know about ext4, but I do recommend using it.

edit: ext4 IS stable according to the kernel.

Absolutely usable at home, even for beginners: ext2, ext3, ext4

Usable at home, rarely with issues: xfs (rarity is extreme rarity), jfs, reiserfs

Usable at home, frequently with issues: btrfs, and yeah, ye olde ntfs and fat (one should never ever use those two on Linux, but who knows?)

Not usable at home: zfs

Ext2 is old, but supported everywhere. For desktop/home server usage, ext3 and ext4 are almost completely equal, both are following the same principles and philosophy. The main difference is the level of maturity: ext4 isn't mature enough, so gigantic production systems don't use it yet (rare instabilities or performance issues might 'ruin' those systems [at least financially :)], but not yours). XFS does have a great performance when a lot of small files are moving (but don't use it in your boot partition - AFAIK it is still not supported officially by GRUB, although, I use it with Debian stable, and it works); JFS and ReiserFS aren't native old-school Linux filesystems, but their integration is more than enough. Btrfs is an emerging brilliant thought, always use it with working backup! From btrfs most distros can't boot now, but the support grows from kernel to kernel. Zfs is not yet for home usage, desktops never could use its functionality by its extreme limits (it is constructed for unreachable limits).
