Intel Optane memory is a type of storage technology designed to enhance the performance of traditional hard drives. It acts as a bridge between the slower hard drive and the faster RAM, allowing frequently accessed data to be stored closer to the processor. This results in quicker boot times and faster application loading. By using 3D XPoint technology, Intel Optane memory provides a significant speed boost compared to standard solid-state drives (SSDs). It is particularly beneficial for users who want to improve their system's responsiveness without fully replacing their hard drive with an SSD.
