Insanely Fast Servers!
NVMe is a new technology that significantly outperforms SSD and HDD.
SSD outperformed HDD because the latency or response time of this storage media improved drastically over mechanical drives by as much a thousand times. One thing HDD and SSD have in common is the SATA interface. SATA was developed with mechanical hard drives in mind, and can’t match PCIe speeds. NVMe servers eliminate that issue.
