Ext4 se basa en una tecnología más antigua, por lo que carece de las características modernas del sistema de archivos que se encuentran en sistemas como E2FS y BtrFS. For storage, XFS is great and sometimes has higher performance than EXT4. The reason that Ext4 is often recommended is that it is the most used and trusted filesystem out there on Linux today. Even if you don’t get the advantages that come from multi-disk systems, you do get the luxury of ZFS snapshots and replication. You might also want to consider Btrfs for your array drives, but you should be aware of the potential risks. , not available on the GUI for now) that allows choosing a file system from a white list, defaulting to ext4. The chart below displays the difference in terms of hard drive space reserved for redundancy. 0 File-System Benchmarks: Btrfs vs. ZFS combines a filesystem and volume manager. Also consider XFS, which works better for extremely large files. LVM has snapshots. XFS is optimized for large file transfers and parallel I/O operations, while ext4 is optimized for general-purpose use with a focus on security. In a significant data corruption, Ext2 and Ext3 file systems are more possible and easy to recover data due to their data redundancy compared with Ext4. I've read and have anecdotally (not scientific and could be affected by other things) experienced Btrfs being slower than ext4. btrfs 可以支援 snapshot, 但 ext4 不行, 如果一開始就採用 ext4, 日後如果要使用 snapshot 功能, 必須將 NAS 的資料備份出來, 重新 format 成 btrfs 格式. 0, and is just some quality-of-life command line. 0.

In a few words, I just need a really reliable and fast filesystem for years ahead, with the care of SSD in mind, I need it mostly for gaming, video-audio production, working with a lot of small/medium files (from 100-500Kb to 100-150Gb) sending them. Now Fedora just needs to implement it properly like openSUSE. XFS still has some reliability issues, but could be good for a large data store where speed matters but rare data loss (e. I switched from ext4 to btrfs a couple of years ago. removes the need for LVM and thus eliminates 1 layer for filesystem-ing (if that’s a word) On top of that, in 2008, the principal developer of EXT3 and. For BTRFS, the overall throughput is fairly low (~30k tps), while the jitter is somewhat better and worse than for EXT4/XFS at the same time. • 3 mo.

The PostgreSQL database server ran well particularly on EXT4 and XFS while F2FS on the USB 3. Since btrfs doesn't have something comparable to the ZVOL the best you can do is use subvolumes which must always use the btrfs file system.
