Which is better, solid-state hard disk or ordinary hard disk?

Solid-state hard disk not only has the characteristics of large capacity of mechanical hard disk, but also has better performance and faster reading and writing speed than mechanical hard disk in power consumption.

When the mechanical hard disk reads and writes data, the disks inside the hard disk need to run at high speed, which determines the high power consumption of the mechanical hard disk. Unlike solid-state drives, which have no mechanical structure, solid-state drives are mainly composed of main control, NAND flash memory and cache, so standby power consumption is excellent.

In addition to the huge gap in standby power consumption, there is also a huge gap in energy consumption ratio between the two. Standby power consumption can be understood as the transmission required to store data. Hard disk not only has the great function of storing data, but also transmits data very commonly. Such as starting the system, editing and loading videos, loading Game model, etc. In this process, the hard disk is transmitting data at full load.

In terms of transmission speed, the continuous reading and writing of NVMe solid-state hard disk can reach 2000M/s+, while the continuous reading and writing of mechanical hard disk is only about 200 m/s. Through the published data, we can get that the working power consumption of mechanical hard disk is about 1 1W, while that of titanium PC005 NVME solid-state hard disk is about 5W, which is ten times higher and only half.

Therefore, whether it is standby or reading and writing, SSD's power consumption performance is far ahead of mechanical HDD. Solid-state hard disk can not only improve the running efficiency of computer, but also be safer than mechanical hard disk in data protection.
