If you building a PC on a budget this year you'll likely find yourself deciding between a high capacity Hard Disk Drive (HDD) or a smaller, albeit faster SATA III Solid-State Drive (SSD). This is where Intel Optane Memory Modules are expected to fit into the market as it combines Intel 3D XPoint Technology with the latest in SSD caching advancements. The idea for SSD caching is that the important recently accessed data is placed onto really fast caching drive (Intel Optane Memory) and can be quickly accessed when needed by the system instead of having to pull the data from the slower hard drive.
