ReFS, the next-generation file system in Windows 8

Chances are that NTFS is the main file system on the computer you are reading this and/or developing your code. For years, I haven't personally had the need to format anything except USB thumb drives to anything else than NTFS.

Now, NTFS is a good and robust filesystem in my opinion, but as technology advances, also file systems need to be upgraded. In Windows 8, we are seeing a new filesystem called ReFS.

New features in ReFS include better resilency against hard drive problems, bit rot and the promise of being "always available".

For developers, the new file system would mean that there are less things to worry about then designing systems that need to withstand a wide variety of problems, both software and hardware.
