Performance:

ZFS RAID support and 128-bit scalability offer better performance compared to Btrfs. The LZ4 compression algorithm used in ZFS is faster than the zlib used in the Btrfs file system.

Features:

Both ZFS and Btrfs support file compression and RAID. The ZFS file system supports RAID-Z, which is equivalent to RAID 5 and RAID 6. RAID 5 allows for one drive to fail without losing data, and RAID 6 allows two drives to fail without losing data. Btrfs supports RAID 0, 1, 5, 6, and 10 (RAID 1 and RAID 0 combined). For deduplication, the ZFS file system supports the reduction of disk space needed when backing up files.

Data integrity and reliability:

If you configure your storage for RAID 1 in Btrfs, then you have mirroring set up, which means that your data is duplicated on a separate disk. This requires additional storage for every drive, so server administrators might prefer the RAID 5 and RAID 6 configurations. Of the two options, RAID 5 is better for performance while still offering data integrity and reliability. RAID 6 allows for two failed disks, but it requires more disk space and doesn’t have the same performance. Use Btrfs for servers that don’t have mission-critical high-traffic applications that must provide fast performance. Use ZFS RAID 6 when you need high levels of data integrity and reliability.

BTRFS vs ZFS?

Once you choose a partitioning format, it’s a lot more effort to change it. Changing the partition requires transitioning to a new disk or repartitioning your current drive, so knowing the difference between Btrfs and ZFS will help you decide the right file system for your servers. The choice you make will determine your available fault tolerance, storage capabilities, performance, and features.

For administrators determining which file system is best for their servers, consider Btrfs as a more basic choice. Servers supporting simple backups or low-volume activity can be configured to use Btrfs with mirroring for better backup performance and data integrity. For critical servers supporting a high volume of requests and important applications, ZFS is the better choice for its performance and RAID-Z features. Another advantage of ZFS is its security and ability to set file access controls across enterprise user accounts.
