However, Intel Optane Memory is based on the company's 3D Xpoint memory technology and is meant to be used as an accelerator for systems with relatively low-speed storage devices, like hard drives. Intel Optane Memory products and associated software are designed to cache the most frequently accessed bits of data on a compatible system, which can significantly increase performance and responsiveness of slower drives. The SSD can be paired to any standard hard drive or SATA drive for that matter, regardless of the capacity. The Optane memory is used as a high-speed repository of the most commonly accessed data blocks (not necessarily complete files). Usage patterns on the hard drive are monitored and the most frequently accessed bits of data are copied from the hard drive to the Optane drive. Because it's is used as a cache, it is not presented to the end-user as a separate volume. The first products in Intel's Optane Memory line-up will be M.2 type NVMe SSDs, with capacities of 16GB and 32GB. Note that Intel Optane Memory will work only on Windows 10 64-bit systems with Intel 7th Gen Kaby Lake-based processors and 200-series chipsets, or newer systems. 16GB and 32GB Intel Optane Memory modules will be available initially through retailers with MSRPs of $44 for the 16GB part and $77 for the 32GB model. There are already over 130 motherboards on the market and systems featuring the technology will be made available soon from all of the major players, including Dell, Lenovo, HP and others.
