Should You Use ReFS Right Now?

Question

NTFS

I buy a new SSD for the system, freeing the HDD from it. I stumbled upon a subject in discussions - it sounds kind of good, you can just format the HDD for it, but is the new file system honed? Or is it likely to run into pitfalls and should not change the old time-tested NTFS yet?
PS: is it true that when formatting the HDD, this file system will eat up 30% of the space? If not, how much, for example, will remain from the hdd for 1TB? There is some conflicting info on the internet.

Answer 1

In 1809, it was removed from the FS selection in the formatting dialog. I would not risk formatting media in ReFS.

Answer 2

Should You Use ReFS Right Now?

Depends on the situation.
I personally do not see any clear advantages at the moment.

Answer 3

Windows 10 won't boot from ReFS, which is only supported under Storage Space.
