There was a paper (in Usenix FAST, I think) about what’s new in ext4. My own experience is with ext4 filesystems of up to 6 TB. The application is radio station automation. A half hour show is about 600GB, so lots of very big files. Total time to do a full fsck is under two minutes. It can be nerve-wracking when the station is down because the server decided to reboot and do an fsck, but it’s *way* better than it used to be with ext3!
