What Is the Difference Between Intel® Optane™ Memory M Series and a Solid-State Drive (SSD)?

Cannot differentiate if the Intel® Optane™ memory is just like another Solid-State Drive (SSD).

While a solid-state drive (SSD) is a device used for data storage, Intel® Optane™ memory is a system acceleration solution installed between the processor and slower storage devices (SATA HDD, SSHD, SSD), which enables the computer to store commonly used data and programs closer to the processor. This allows the system to access this information more quickly, which can improve overall system responsiveness.

Intel® Optane™ memory uses non-volatile Intel® Optane™ memory media with the Intel® Rapid Storage Technology driver to accelerate your PC's access to non-volatile data. In your PC, non-volatile data is your computer's "long-term memory" that persists even when the PC is powered off. A PC user's personal documents, pictures, videos, music, and application files are examples of non-volatile data.
