Currently I'm running on LVM with SSD caching and ext4 fs. Each of the tested file-systems were carried out with the default mount options in an out-of-the-box manner. a lot of btrfs' perception of 'breaking' is actually due to checksums (correctly) finding fault on a users data and (correctly) not allowing mounting of the filesystem until it's fixed. 其他 ext4 文件系统实用程序 6.

Each of the five file-systems were tested on the same NVM Express SSD from the Linux 4. BTRFS also had somewhat higher latency than EXT4, meaning that it took longer for files to be accessed on the file system. However benchmarks test quite narrow parameters which may not be reflected by running an OS. If you wish to run ext4, xfs or btrfs then you need to run a linux OS not BSD. Linux 5.
