About this tag
The ssd cache tag on WindowsForum.com covers discussion of when adding flash storage as a cache layer actually improves performance and when it does not.

It also considers everyday Windows workloads like file copies, media playback, and browsing, where an expensive cache upgrade may leave the experience unchanged.

    NAS SSD Cache: When It Helps—and When It Does Not

    An SSD cache can be one of the most effective upgrades available for a NAS—or an expensive change that leaves Windows file copies, media playback, and everyday browsing feeling exactly the same. The difference is not whether flash storage is inherently fast. It is whether the NAS can serve a...
