I had no bad experience myself with btrfs so far, but still have not tried it with anything more complex than raid1 over a long time and while I assume many horror stories out there are just deprecated as btrfs keeps improving, it can do a lot more than ext4. However, we also must admit that Btrfs has many advantages that Ext4 doesn’t have, for example:8. The reason that Ext4 is often recommended is that it is the most used and trusted filesystem out there on Linux today. To organize that data, ZFS uses a flexible tree in which each new system is a child. There are two ways this can be done. So…. I've never had an issue with either, and currently run btrfs + luks. Btrfs also has snapshots so you can revert back to an earlier snapshot easily, say you run arch and some update borks your system (highly unlikely), you can simply revert back to the last good snapshot. Btrfs is slower, especially on non-SSDs, because of CoW, but has a whole lot more going on under the hood in way of features and data integrity. My current setup is /@ for the rootfs, /@home for home dir, works great. Either way you go, just leave EXT4 where it is, in the ground. BtrFS RAID 6 implementation is "mostly working", see here:As some of you likely know, I have a favorable view of ZFS and especially of MySQL on ZFS. BTRFS is good for rotational drives too, but it's still not fully mature and I'm hesitant to recommend it because of previous issues with data.

EXT4 is better for small files and day to day use. EXT4 is better for small files and day to day use. But to be honest, it might be easier for me to work around than the lack of the possibility for single-file clone that btrfs, XFS etc. XFS still has some reliability issues, but could be good for a large data store where speed matters but rare data loss (e. If you are looking for advanced features such as data checksumming, snapshots, and data deduplication, then Btrfs may be the better option. Btrfs, EXT4, F2FS, and XFS were tested in their out-of-the-box state / default mount options. Pro: supported by all distro's, commercial and not, and based on ext3, so it's widely tested, stable and proven. More uniquely, checksumming can detect errors in the data itself. Phoronix: Linux 4. org Phoronix Test Suite Intel Xeon E3-1280 v5 @ 4. Per the recommendation from RedHat: Another way to characterize this is that the Ext4 file system variants tend to perform better on systems that have limited I/O capability. It's got good features. XFS is Red Hat’s enterprise filesystem (until they finally trust btrfs). 6. I'd like to take advantage of an OS switch to upgrade to BTRFS. Definitely ext4. EXT4. Journaling ensures file system integrity after system crashes (for example, due to power outages) by keeping a record of file system.

The XFS supports more file sizes and greater file or partition sizes. I remember being on ext4 using Timeshift but it only supports rsync–so slow. The 3TB HDD are ext4. Let’s talk about the advantages Btrfs boasts over the traditional and more popular ext4 filesystem. I know the latest versions do not setup /home in a separate partition anymore but as a btrfs subvolume instead. Next lets detect the operating systems on the root file-system. Conclusion: Last time I ran these tests, xfs and ext4 pulled very similar results, and both were miles ahead of btrfs. The ZFS file system combines a volume manager and file. I currently have a ds1819+, currently, i have 8 x 4tb (5400rpm) 32G of ram 2x2tb nvme cachethe system is super fragmented and super slow synology says that i need to backup everything and recreate the volume. , not available on the GUI for now) that allows choosing a file system from a white list, defaulting to ext4.
