Advantages of NVMe SSD Technology!
What is NVMe SSD Storage?
NVMe stands for Non-Volatile Memory Express and is sometimes described in more technical detail as Non-Volatile Memory Host Controller Interface Specification (NVMHCIS). It’s a standard for accessing non-volatile storage (such as an SSD) using a technology known as PCI Express (Peripheral Component Interconnect Express) or simply PCIe. Originally developed to allow high-speed data transfer between computer components and systems, PCIe has been around for over a decade – but it’s only with NVMe that a standard specification for PCIe-based storage has emerged.
SSD comes from Solid State Drive, a modern storage device that doesn’t have any moving parts. It is also known as a solid-state disk for historical reasons, even if it is not actually a disk.
SSD drives are a lot faster than hard disks (HDD) but they used to be very expensive, preventing their widespread use. However, prices have decreased significantly and the gap is relatively small today.
Advantages of NVMe SSD
SSD drives that use NVMe are the fastest storage solutions available for your server today. NVMe guarantees very fast data access, which is especially important for modern multi-core computers. Due to the large bandwidth and built-in parallelism, these drives allow multiple cores to execute write and read operations at the same time, with no I/O wait.
Benchmarks show that NVMe interfaces are twice as fast as the best SAS available and between 4 and 6 times more effective than a conventional SATA port.
Any I/O-bound application benefits from the performance improvements of NVMe.The technology is likely to be of particular interest to dedicated game server hosting clients, who will be able to move data from SSD drives to GPUs and CPUs much more quickly than has ever been possible before, enhancing game performance and maximizing the utilization of expensive processor and graphics hardware.
NVMe is often used to host a caching layer for large databases and can offer speed increases for databases of any size. The same is true for complex web sites and eCommerce stores that require a lot of disk access. NVMe is great for hosting virtual machines.
The result is a massive I/O performance boost. SATA provides maximum bandwidths of around 750Mb/s. A single PCIe lane can move 965Mb/s, and NVMe uses 8 PCIe lanes in parallel, delivering bandwidths of up to 2.8 GB/s.
