Windows Storage Spaces: Storage Virtualization for Diverse Disks
Windows Storage Spaces combines multiple disks into storage pools, offering fault tolerance through mirroring or parity and spanning across different-sized disks.
What is Windows Storage Spaces?
Windows Storage Spaces is a storage virtualization technology introduced in Windows Server 2012 and Windows 8 that allows combining multiple disks into storage pools. It provides an abstraction layer over the physical disks and allows creating virtual disks called storage spaces.
Some key features of Storage Spaces:
- It allows combining different types of disks like SSDs, HDDs and even cloud storage into a storage pool.
- Provides resiliency against disk failures using mirroring or parity mechanisms to provide fault tolerance.
- Supports thin provisioning so storage can be overallocated.
- Storage pools can span across disks of differing sizes.
- Data can be tiered across different types of disks in the pool automatically or manually.
- Supports scalability by allowing new disks to be added to pool.
- Included in Windows Server and Windows client operating systems by default.
By utilizing commodity disks in a pool and providing abstraction, Storage Spaces aims for cost-effective storage virtualization compared to SAN/NAS solutions. The fault tolerance mechanisms help against data loss due to disk failures.

PrimoCache
PrimoCache is caching software designed to speed up computers by caching frequently accessed files and data in RAM instead of reading from your hard drive each time. It works by monitoring disk activity and remembering what files and applications are used the most.When those files are needed again, PrimoCache retrieves...
Open Cache Acceleration Software (Open CAS)
Open CAS is an open source distributed caching software for accelerating applications and reducing load on spinning disks. It works by caching data in the system's RAM or SSD instead of spinning hard drives. This boosts performance by reducing mechanical disk access, allowing high system bandwidth and low latency for...
