Windows Along with Storage Spaces coming in Windows 8, ReFS forms the foundation of storage on Windows for the next decade or more. Key features of the two when used together include: metadata integrity with checksums; integrity streams providing optional user data integrity; allocate on write transactional model for robust disk updates; large volume, file and directory sizes; storage pooling and virtualization making file system creation and management easy; data striping for performance and redundancy for fault tolerance; disk scrubbing for protection against latent disk errors; resiliency to corruptions with "salvage" for maximum volume availability in all cases; and shared storage pools across machines for additional failure tolerance and load balancing.

RE[2]: What Will Be Removed

Member since:

That's my thought as well. As they implement ReFS onto the client (perhaps with Windows 9, perhaps with a service pack to Windows 8) they'll have to add important features that clients use.

For the server environment, the features they removed won't be missed considering Storage Pools and ReFS (with copy on write semantics) supersede them. Server 8 will have deduplication, which takes care of the need for Sparse files, hard links, and compression. It's probably needlessly complex to support all the dropped features considering the new file system and storage pool.

But for the client, Sparse files are critical because large files would take forever to allocate on typical HDDs. Hard links I'm not so sure about, because they are rarely used in Windows, but they are still nice to have for the client without dedup.

Finally, removing those other features is actually a good thing considering malware. Often all those obscure NTFS features are used to hide malware so deep in NTFS only specialized tools can find them.
