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.
It's important to note that the Intel® Optane™ memory is not intended to replace the main drive in the system, but instead accelerate a slower storage device already in the system; which could be the main drive or a secondary drive.
It enables faster task completion and reduces the wait time, compared to a computer with a hard disk drive alone.

Intel® Optane™ memory is built to address the need for non-volatile, high-performance, high-endurance, low latency, and Quality of Service (QoS). The combination of these attributes in a memory technology sets it apart from anything else.
Intel® Optane™ memory is different from other NAND caching solutions for the following reasons:
Intel® Optane™ memory uses non-volatile Intel® Optane™ memory media with the Intel® Rapid Storage Technology driver to accelerate your PC's accesses 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.
DRAM, or Dynamic Random Access Memory, is a volatile memory technology that serves as your computer's "short-term working memory." DRAM temporarily stores the inputs and results of calculations performed by the processor. When the PC is powered off, the data in the DRAM disappears.
The two memory technologies serve different purposes in the PC memory hierarchy, so Intel® Optane™ memory complements DRAM, rather than replacing it entirely. A computer with both Intel® Optane™ memory and DRAM can access programs and data faster, providing additional performance and responsiveness.
No, Intel® Optane™ memory requires the Windows 10/11* 64-bit operating system and the Intel® Rapid Storage Technology (Intel® RST) driver software. Using the device with other software for caching is is not supported or validated.

Intel® Optane™ memory can accelerate one drive. The system may have multiple drives (or add additional drives later one), but Intel® Optane™ memory can only accelerate one drive, which could be the main drive or a secondary drive.
Intel® Optane™ memory must be disabled before moving to another computer. Pick the method that best suits your system How to Disable System Acceleration with Intel® Optane™ Memory.
The volume (module + drive being accelerated) will go offline to protect user data. You won't be able to access the drive that was being accelerated until the module is placed back in the system.
When an Intel® Optane™ memory volume (drive being accelerated + Intel® Optane™ memory module pair) is created they are paired together and cannot be separated. If one is missing from the system, the other disk goes offline and the OS no longer detects it.
