In the Fall Creators Update, Microsoft is removing the ability to create volumes using its new ReFS file system from Windows 10 Pro. Existing volumes will continue to work, but Pro will no longer be able to create new ones.
After rumors in June, Microsoft confirmed last week that it was producing yet another variant of Windows 10: Pro for Workstations. The main features of this build are that it lifts certain limits found in regular Pro: up to four processors (compared to two in Pro) and 6TB of RAM (compared to 2TB). It also has support for certain exotic server-grade hardware, including non-volatile main memory and high-speed network adaptors.
Microsoft is promoting one final feature in Pro for Workstations: its new, modern file system, ReFS (“resilient file system”). ReFS—like modern file systems on other platforms such as Oracle’s ZFS and Linux’s btrfs—includes integrated checksums to detect data corruption. Combined with Storage Spaces, it can automatically reconstruct damaged data from software-defined arrays.
