NVMe is a communications standard/protocol developed specially for SSDs by a consortium of vendors including Intel, Samsung, Sandisk, Dell, and Seagate. It operates across the PCIe bus (hence the ‘Express’ in the name), which allows the drives to act more like the fast memory that they are, rather than the hard disks they imitate. Bottom line: NVMe is fast. Really fast. Like never-have-to-wait-again-for-your-computer fast.
NVMe (Non-Volatile Memory Express) is a new protocol for accessing high-speed storage media that brings many advantages compared to legacy protocols. But what is NVMe and why is it important for data-driven businesses?
As businesses contend with the perpetual growth of data, they need to rethink how data is captured, preserved, accessed and transformed. Performance, economics and endurance of data at scale is paramount. NVMe is having a great impact on businesses and what they can do with data.
NVMe is a high-performance, NUMA (Non Uniform Memory Access) optimized, and highly scalable storage protocol, that connects the host to the memory subsystem. The NVMe protocol is relatively new, feature-rich, and designed from the ground up for non-volatile memory media (NAND and Persistent Memory) directly connected to CPU via PCIe interface . The NVMe protocol is built on high speed PCIe lanes. PCIe Gen 3.0 link can offer transfer speed more than 2x than that of SATA interface.
