That’s why XFS remains one of the best options for systems that are constantly reading and writing data. XFS was created by Silicon Graphics almost three decades ago for their graphics workstations specializing in rendering 3D graphics. It’s worth noting that BtrFS is also “SSD-friendly” since it automatically disables its features that are useful for mechanical HDDs but could wear out SSDs. Thus, in case of a failure, it can pull information from backups and checksums to reconstruct corrupted or missing data.
Instead, it ensures that each block on one device has a copy on another and keeps CRCs for all data. Online and offline filesystem checks further reduce the possibility of data loss.ītrFS natively supports RAID, but it doesn’t follow the approach of typical software RAID striping or hardware block mirroring. This also allows for snapshots of different states of the filesystem as well as easy replication, migration, and incremental backups. It follows a copy-on-write approach, saving new iterations of data and metadata instead of affecting the existing ones (“shadowing”). Btrfs comes with advanced features, such as automatic defragmentation and transparent compression.
