Windows Server 2012 comes with the new File System ReFS, which is Microsoft's upgrade to NTFS. Is there any way to use this for my Windows 8 partition?

Microsoft is planning to upgrade ReFS to be capable of being a boot volume, but no time span has been given yet.

With this in mind, we will implement ReFS in a staged evolution of the feature: first as a storage system for Windows Server, then as storage for clients, and then ultimately as a boot volume. This is the same approach we have used with new file systems in the past.

+1. My answer has a list of other things wrong with it, but not being a boot volume is up there :-) –  user3463 Oct 29 '12 at 17:42

In its current iteration, it is not an upgrade to NTFS.

According to this article by Denny Cherry:

The NTFS features we have chosen to not support in ReFS are: named streams, object IDs, short names, compression, file level encryption (EFS), user data transactions, sparse, hard-links, extended attributes, and quotas.

In my mind, this is a significant list of reasons why you shouldn't even consider ReFS for the immediate future.

If this changes and they support those features, then I may consider changing my mind. But it's a storage-first model at the moment, and I wouldn't touch it for a desktop environment.

+1. Nice list. I'm not sure what those things are, but if they make it a boot vector and optimize it for consumer user storage, I'd use it. –  Caleb Jares Oct 29 '12 at 17:44

Things like EFS, hard links and quotas are a non-starter in a corporate environment. Personally, I use a number of these features as well, though I do consider myself an edge-case user. But yeah, bootable is important too :-) –  user3463 Oct 29 '12 at 17:46
