3 Reasons an SSD Beats a RAM Cache for Most People

RAM caches are volatile and expensive A RAM cache like PrimoCache disappears on reboot, so any cached data is lost if the power blinks. That 64GB of system RAM costs about the same as a 1TB SATA SSD, which stores data persistently.

An SSD eliminates the bottleneck entirely A RAM cache on an HDD still leaves the spinning disk as the bottleneck for sustained writes and large transfers. An SSD replaces the bottleneck with no configuration or software needed.

RAM caches add complexity for little gain Setting up a RAM cache requires software, trial periods, and potential performance issues like sudden write slowdowns. An SSD is plug-and-play and works reliably out of the box.
