![]() In fact, it can also optionally inspect the checksums for file data, which may take more time, but the data can be fully validated.Īpart from that, ReFS comes with Storage Spaces integration, which repairs the errors automatically. It employs something called integrity streams that basically analyze the checksums for metadata to precisely detect the error. Basically, ReFS can automatically repair data corruption, making it stand on par with competing file systems like Btrfs and ZFS. ![]() The first and foremost feature that makes ReFS a resilient file system, unlike NTFS, is the built-in ability to accurately detect corruption and fix them without rebooting the system. NTFS vs ReFS: Key Features Differences Resiliency to Data Corruption In a single instruction, it can read and write data on files, lowering disk input and output operations, and bringing disk usage, memory, and power consumption down. ![]() The on-disk structure for both metadata and file data is based on B+ trees.Īpart from that, ReFS uses an allocation-on-write (also called copy-on-write) strategy for metadata to avoid data corruption during an unexpected shutdown. The root can be a node with multiple children or a leaf. Unlike the B-tree structure in NTFS, ReFS utilizes B+ trees, which include root, internal nodes, and leaves. It actually uses some of the NTFS code and has derived most of the features too. ReFS is not a new file system developed from the ground up.
