What does pcle nvme mean?
1. PCI-e refers to the hard disk channel, and NVMe is the hard disk protocol;
2. Generally, solid-state drives that currently support the NVMe protocol occupy the PCI-e channels of the motherboard and CPU, but some occupy the PCI-e3.0x2 channel and some occupy the PCI-e3.0x4 channel.
What does nvme protocol mean?
1. The full name of nvme protocol is Non-VolatitControllerInterface advanced host control interface. It is both an interface and a protocol. It is also a technology developed and led by Intel. Its emergence has made a big leap in the performance of solid-state drive products. According to test results , the emergence of AHCI has improved the performance of solid-state drive products by at least 30%, and is currently the most mainstream solid-state drive interface protocol.
2. The hard disk interface is the connection component between the hard disk and the host system. Its function is to transmit data between the hard disk cache and the host memory. Different hard disk interfaces determine the connection speed between the hard disk and the computer. In the entire system, the quality of the hard disk interface directly affects the speed of program running and the performance of the system. From an overall perspective, hard disk interfaces are divided into four types: IDE, SATA, SCSI and Fiber Channel.
3. From an overall perspective, hard disk interfaces are divided into four types: IDE, SATA, SCSI and Fiber Channel. IDE interface hard disks are mostly used in home products and are also partially used in servers. SCSI interface hard disks are mainly used in the server market. Fiber Channel is only used on high-end servers and is expensive. SATA is mainly used in the home market, including SATA, SATA ΙΙ, and SATA ΙΙΙ, which are now mainstream.
