How fast is the transmission speed of the mechanical hard disk in the computer
Editor to share with you how fast the transmission speed of the mechanical hard disk in the computer. I hope you will get something after reading this article. Let's discuss it together.
The transmission speed of mechanical hard disk, that is, write speed and read-write speed, is generally about "120MB/S", while the speed of solid-state hard disk based on SATA protocol is about "500MB/S". The mechanical hard disk is mainly composed of disk, magnetic head, disk spindle, control motor, head controller, data converter, interface, cache and so on.
The write speed and read-write speed of the mechanical hard disk is generally about 120MB. The speed of the solid-state disk of the SATA protocol is about 500MB. The speed of the solid-state disk of the SMagne NVMe protocol (PCIe 3.0 × 2) is about 1800MB. The speed of the solid-state disk of the SMagne NVMe protocol (PCIe 3.0 × 4) is about 3500MB/S.
The mechanical hard disk is mainly composed of disk, magnetic head, disk rotating shaft and control motor, magnetic head controller, data converter, interface, cache and so on.
Extended data
The capacity of the hard disk: the capacity of the hard disk is in megabytes (MB) or gigabytes (GB). The capacity of the hard disk is 1GB, 1024MB, and 1024GB. However, hard disk manufacturers usually use 1G=1000MB when labeling the hard disk capacity, so the capacity seen in BIOS or when formatting the hard disk will be smaller than the manufacturer's nominal value.
The capacity index of the hard disk also includes the single disk capacity of the hard disk. The larger the disc capacity, the lower the unit cost and the shorter the average access time. The mainstream hard disk is 500 gigabytes, and high-capacity hard drives with more than 750 gigabytes have become popular.
