A Brief Overview On NVMe SSD

The NVMe (Non-Volatile Memory Express) is an interface to communicate and drive that specifies the commands and functions that are applicable to PCIe SSD-based drives , with the intention of improving efficiency and enhancing interoperability between various client and enterprise systems.

NVMe was designed to work with SSDs. The communication between the interface for memory and the processor of the system is done via the high-speed PCIe connector regardless of the form dimension. Navigate to to buy a good quality NVMe SSD.

Specially designed to be used with SSDs specifically, NVMe SSD sets the new benchmark for servers in the datacenter as well as client devices like laptops or desktops, as well as the next generation of game consoles.

NVMe technology can be found in a variety of forms including PCIe M.2 as well as U.2 slot cards. Although there are SSDs that utilize SATA PCIe slots and M.2 which are significantly more AHCI than NVMe, U.2 is a form factor that utilizes the NVMe protocol solely.

The moment NAND-based SSDs first appeared on the marketplace, it became evident to the industry that new protocols and buses were required.

* The initial SSDs were slow, and the current SATA storage infrastructure was able to be used with ease. While it is true that the SATA bus has increased to 16 Gbps but the majority of commercial applications of the SATA bus still run at 6 Gbps.

* The performance for PCIe 3.0 can be 16 Gbps and PCIe 4.0 is twice the speed that PCIe 3.0. It can offer as many as 16 bands, and can transfer data at speeds of up to 32,000 MB/s. SATA III only transfers up 600 MB/s.
