What is the main difference between M2 and NVMe?
The main difference between M2 and NVMe lies in their interface and architecture. M2 is a physical interface that allows for faster speeds and lower latency, while NVMe is a protocol that enables faster data transfer rates. In other words, M2 is the hardware, and NVMe is the software that runs on it.
While M2 provides the physical connection, NVMe is the protocol that allows for faster data transfer rates. NVMe is designed to take advantage of the faster speeds offered by M2, allowing for faster data transfer rates and lower latency. This means that NVMe drives can reach speeds of up to 5000 MB/s, while M2 drives without NVMe can only reach speeds of up to 600 MB/s.
