Origin Of Nvme Standard (also Known As Protocol)

The SATA interface and AHCI standard used now are actually designed for mechanical hard disks with high latency. At present, mainstream SSDs still use them. When the performance of early SSDs was not high, they may not feel that there was any problem. However, with the gradual enhancement of the performance of SSDs, these standards have become a bottleneck limiting SSDs. The AHCI standard designed for mechanical hard disks is not suitable for low latency SSDs

Of course, the industry has long recognized this problem. In the second half of 2009, the technical work on nvme was officially launched. The nvme specification was customized by a working group including more than 90 companies. Intel was the main leader, and the members of the group included micron, Dell, Samsung and Marvell

NetApp, EMC, IDT and other companies aim to establish new storage specifications and standards for SSDs and free them from the old SATA and AHCI.

In 2011, the nvme standard was officially released. The standard was customized according to the characteristics of flash memory storage. The new standard removes the old standard from SSD Various restrictions on. The standard was upgraded to nvme 1.1 in 2012, and the latest nvme 1.2 standard was launched in 2014.

The first product that supports nvme standard is Samsung xs1715, which was released in July 2013. Subsequently, enterprise class nvme standard SSDs were launched one after another. It was not until Intel 750 was released this year that nvme standard products began to enter the consumer market.
