NVMe(tm) (Non-Volatile Memory Express) is a brand-new protocol to access high-speed storage media, which has many advantages when compared with older protocols.
The performance, economics and durability of data at large scales is crucial. NVMe has a significant impact on companies and how they can accomplish with data especially Fast Data for real-time analytics and the emergence of new technologies.
The change NVMe brings to data centers and the ability the company has to offer Western
Digital to deliver innovation across the stack. NVMe can open a whole new world of possibilities making it easier to work with data! You can also buy 2tb nvme ssd by browsing through online sources.
Flash-based SSDs utilized the SATA/SAS legacy Physical interfaces, protocols and form factors, in order to limit modifications to the present hard disk (HDD)-based storage/server for enterprise systems.
But the protocols or interfaces were specifically designed for storage media with high speed (i.e. NAND permanent memory). Due to the speed of the interface as well as the performance of the new storage media, and its proximity with the processor, PCI Express (PCIe) is the following natural storage interface.
The PCIe slot directly connects to the CPU and provides memory-like access . They can also operate a very effective software stack. However, the early PCIe interface SSDs didn't have the industry standard features nor were they designed for enterprise use.
PCIe SSDs relied on the proprietary software, and proved challenging to scale up systems due to many reasons, including the difficulty of managing and running device firmware,
and b) compatibility issues between the device and firmware with various system software and software, in addition,) failing to make the the best use of the available lanes and proximity to the CPU, and d) insufficient high-value features designed for business applications. The NVMe specifications were developed primarily due to these issues.
