## Benefits

![Superior Speed](https://www.layerstack.com/assets/img/nvme/layerstack-icon-dedicated-bandwidth.svg)

### **Superior Speed**

Enterprise NVMe SSD takes the full advantages of CPU utilization and high performance flash memory. This greatly increases the performance and efficiency of instances.

![High I/O consistency](https://www.layerstack.com/assets/img/nvme/layerstack-icon-high-io-consistency.svg)

### **High I/O consistency**

With running multiple I/O operations simultaneously, NVMe SSD enables the processing of multicore and provides the Quality of Service (QoS).

![Lower Latencies](https://www.layerstack.com/assets/img/nvme/layerstack-icon-low-latency.svg)

### **Lower Latencies**

By connecting vCPU via PCI Express (PCIe) interface, less than half of the number of vCPU instructions are required to process the I/O requests.

## Why PCIe Gen 4 NVMe SSD over Traditional SSD?

![Why PCIe Gen 4 NVMe SSD over Traditional SSD](https://www.layerstack.com/assets/img/nvme/layerstack-graphic-why-pcie-gen-4-nvme-ssd.svg)

Compared with traditional SSD, NVMe SSD can handle multiple streams of data at the same time and provide faster speeds. In addition, data can be written simultaneously by allowing the data division and streamline through NVMe SSD. This results in faster interfaces and optimised routines for writing data to the SSD.

## Performance Comparison

NVMe technology provides advanced storage, speed and compatibility. Compared with SATA SSD, NVMe SSD transfers 25 times more data by using PCIe sockets. And the commands of NVMe SSD are 2 times faster compared to that of AHCI drives. Moreover, the input/output operations per second (IOPS) from NVMe SSD exceeds 1 million and is up to 900% faster than that of AHCI drives.
