NVMe Monitoring
What Is NVMe?
NVMe, or Non-Volatile Memory Express, is a storage protocol designed to capitalize on the low latency and internal parallelism of solid-state drives (SSDs). It is widely embraced for boosting storage performance and is crucial for applications demanding high data throughput and speed. NVMe allows for direct CPU communication, drastically reducing data transfer overhead compared to legacy protocols like SATA.
