Details
Btrfs File System has proven to be the most stable commercial use, but concerns have been raised about Btrfs RAID having parity calculation errors, resulting in unrecoverable data loss. The diagram below illustrates how Btrfs RAID takes over the entire communication between the Btrfs file system layer and the disks.
Due to the Btrfs RAID issues, Synology chose Linux RAID. Based on the diagram below, Synology has implemented the layers in between the file systems and disks to ensure that Synology has full control to achieve the highest stability.
