Intel Optane Review

In 2015, Intel and Micron introduced 3D XPoint, a non-volatile memory storage device that promises to be 1000 times faster than NAND, using electrical resistance and offering better endurance with a wear leveling of 30 full drive writes per day for five years. Intel's Optane SSD DC P4800X, based on this technology, is designed for PCI Express or NVMe slots in servers and boasts low latency and high throughput, making it suitable as both a memory cache and persistent storage. Performance tests show that Optane drives excel in low queue depth scenarios, significantly enhancing CPU utilization and offering consistent ultra-fast service, which can reduce total cost of ownership and expand capabilities for data centers. The technology supports near real-time data access with sub-millisecond read and write latencies, addressing challenges like cold-cache warming and data resiliency.
