Hi All,

I asked a similar question in January this year regarding improvements to Storage Spaces and ReFS and no one had any information then but perhaps they do now. Microsoft is busily adding some good features to 2016 in the storage space, yay pun, but they are missing some key low level features in ReFS and Storage Spaces.

1)  Storage Spaces parity block re-leveling.
This needs to happen via GUI or command line; an administrator should be able to re-level the parity blocks for a storage space across the new disks added to a storage space. We shouldn't have issues with artificial limitations on a storage space resize because of this problem.

2) ReFS Feature additions.
Microsoft's current attitude to ReFS is that it's a large data volume storage file system with limited uses. Fortunately for Microsoft ReFS performs very well when combined with SSDs for journaling and write back cache in parity spaces but for it to be a practical Logical Volume Manager and General Purpose File System in the era of expanding storage and large files it needs to be feature competitive with systems like ZFS and BTRFS; this includes file system features like Encrypted File System, Compression and Quotas. Windows admins don't want to start having to make hard choices and sacrifices as their file systems become larger and larger, as is absolutely inevitable.  

There are some really good things in 2016 that I like but ReFS and Storage Spaces still need some critical work to provide an effective foundation for this new operating system.
