EXT4 - I just don't get it.

How about trying btrfs?? Can be used in 10.10 as long as you keep /boot separate with an older fs such as ext2.

Yeah, btrfs, what a nightmare, sorry to say. It seems like it's good, but whenever I'd have large data operations going my computer would freeze until it was finished. And the data throughputs weren't all that great either, it was about the same as ext3. BTRFS does have some work before it'll be good. So I'm sticking with XFS - I just reformatted last night to get away from BTRFS cause I do a lot with VMs and the disk activity of just loading a VM was enough to bring my system to its knees.

btrfs is not ready for mainstream use. The specifications are still being laid out and the code base is still in development.

It also can't be fscked as there is no stable utility to do so.

BTRFS is abysmally slow at this point, I made the mistake of using it on a system with a Celeron and 512Mb ram. Boot-up seems to be ok, but any file operations seem to take forever. Updating from Maverick to Natty took well over 4 hours, where it usually takes less than an hour on the same system.

The only problamatic file system I have had with Ubuntu was NTFS.

EXT4 since I was an option has never gone worng for me.

My other favo is XFS but its too slow dealing with small files. and you can't shrink partitions.

If you experience data corruption on such large scale it could really be a disk problem or information transfer issue.

Most of the documented cases where EXT4 has failed is because of the user incorrectly shut down.

To install 143 updates on Mint, it took 3 hours! It was horrible. I just did it like an hour ago and it only took like 15-20 min for the 143 updates, maybe less.

Seeing that EXT4 is now being made the default file system in so many distro's (Red Hat as well) I can't believe there is a major corruption problem with it... it wouldn't make sense...

I thought google had moved all their servers to ext4. I'd be surprised if there were major problems with it.

Google's engineers are known for extending open projects to meet Google's massive enterprise scale. Usage by Google, or any other huge company with near-limitless engineering capacity, shouldn't act as an endorsement, as their setup very well may not be the stock code available to us.

Haven't run into any data corruption issues since I migrated to ext4 a while ago. I use it on my RAID array, OS drives and backup drives.
