Who has already tested ReFS (the new file system from Microsoft)?
Everyone like me just recently learned about it, here are some materials:
Rus:
ReFS on Wikipedia
ReFS on Habr
ReFS on the Microsoft website
Eng:
The first and largest mention in the Microsoft blog
About sparse files, last entry in 2015
There is no specific question if someone used or uses share your impressions, maybe bugs.
At home, I formatted an external drive and wrote data there, which I don’t mind losing, if anything. So far I have not found any problems (2 days), I use Windows 10 64bit for tests.
Many small files, of course, began to take up a little more space, but perhaps because of the large blocks, working with them became faster.
Trying to make fault-tolerant storage using Storage Spaces is similar to the well-known LVM in Linux.
Has anyone done tests or uses in their home server?
Is there any latest news on development, tests - the given data that I found is slightly outdated and refers to the time of the release of Windows 8 and the tests of the still raw implementation. Although I don't know how far it has progressed.
UPD: I found a lot of material on Storage Spaces in English. here (haven't read it yet)
Thank you for your attention!

Answer 1

IMHO, judging by the descriptions, it looks still damp.

Answer 2

Another FS is not needed.
Let them cut support for FS from the world of * nix systems.
