Deployments with all HDD are not supported. These can be combined in various ways, which we group into two categories: 'all-flash' and 'hybrid'. HDD refers to rotational, magnetic hard disk drives, which offer vast storage capacity at a low cost.

SSD refers to solid-state drives, which connect via conventional SATA or SAS. NVMe offers higher IOPS and I/O throughput with lower latency than any other type of drive we support today except PMem. Common form factors are 2.5' U.2, PCIe Add-In-Card (AIC), and M.2. NVMe (Non-Volatile Memory Express) refers to solid-state drives that sit directly on the PCIe bus. PMem refers to persistent memory, a new type of low latency, high performance storage. Storage Spaces Direct currently works with four types of drives: Type of drive How the cache works depends on the types of drives present.

In most cases, no manual management whatsoever is required. It's a large, persistent, real-time read and write cache that is configured automatically upon deployment. Storage Spaces Direct, the foundational storage virtualization technology behind Azure Stack HCI and Windows Server, features a built-in server-side cache to maximize storage performance while reducing costs.
