ZFS/btrfs/ext4

I have a 150GB partition (on a drive shared with a Vista installation I need to clean up) on which I am to place torrents of shows and music. Large files, write once (and write slowly, in the case of torrents) and read variably. Data integrity and longevity are my favourite.

I already stuck btrfs on top of ext4 and lost 50GB of free space (with only 6GB of data there in the first place). Should I bother trying zfs or just revert to ext4 and hope I notice my disk dying in time?

Also to stay on topic, post your favourite touhou and their favourite programming language.

Then use ZFS, ``faggot''.

My favorite Touhou is Kawashiro Nitori and she made an ANSI C compiler in Haskell.

If you place btrfs on top of ext4 you're gonna get the reliability of ext4 with the bloat and maturity of btrfs.

On a dying HDD with random read/write errors:
- ext* freezes for a while at every error, until metadata is affected and it starts remounting read-only
- Btrfs keeps running nicely, but you need to run scrub to correct metadata errors and detect corruptions
- windows on NTFS seems less sensitive and usually keeps running without warnings until it's too late

I'd choose a largefile ext4 partition using noatime for partial torrent data, then move it to the btrfs partition.

It's called the zettabyte filesystem because that's how much RAM you need to run it.

It's a tradeoff between memory usage and data integrity and I'm willing to accept it. If OP really is concerned about data integrity, he should be too.
