Product Overview

Unraid

Description: Unraid is an operating system optimized for media storage and servers. It supports combining hard drives of different sizes into a single storage pool, parity-based data protection, on-the-fly disk encryption, and Docker containers.

Windows Storage Spaces

Description: Windows Storage Spaces is a storage virtualization technology in Windows that allows combining multiple disks into storage pools. It provides fault tolerance using mirroring or parity and allows spanning pools across disks of different sizes.
