If you run macOS systems, Apple did a lot of work in the hardware driver for the Fusion hybrid drives. The OS watches what files are being used, written to and read from, and moves files that are being used a lot to the flash media dynamically where files that are only occasionally read or written to are kept on the spinning media. This software smarts enable a hybrid drive to operate almost indistinguishably from an SSD in practical use; it means that you can buy storage space at less than half what a comparably sized SSD would cost.
