hesela.devStorage Spaces
Storage Spaces is Windows storage virtualization that pools physical drives and exposes virtual disks with selectable storage layouts.
Pools supply virtual disks called storage spaces. Simple spaces stripe data without drive-failure redundancy; mirror and parity layouts add different forms of redundancy. Pooling alone therefore does not establish fault tolerance. [1]
Storage Spaces manages virtual-disk layout, while ReFS supplies filesystem behavior. ReFS repair requires usable redundant data, while file-data checksum coverage depends on integrity-stream settings. [2]
