Learn about hard drives:
Hard disk is one of the important hardware in the composition of the computer, hard disk can be divided into three types, namely: mechanical hard disk, hybrid hard disk and solid state drive, the difference is that its read and write speed is different. The read and write speed of SSD is greater than that of hybrid hard disk, the read speed of hybrid hard disk is greater than that of traditional mechanical hard disk, and the main role of hard disk in the computer is to store and load the computer operating system, followed by the storage and loading of user software and data. The loading time of the operating system and user software is the running speed of the computer, professional words may be some friends do not understand, then simply and directly click it, after the computer is installed on the solid state drive, the boot speed is generally within 10 seconds, open the commonly used software to enter the software generally no more than 2 seconds, specifically depends on the size of the software capacity, cancel the mechanical hard disk into the program after the mouse circle link.
The speed of mechanical hard disk reading data in the ideal state is generally only about 70MB/s, and the worst performance of the solid-state drive on the market reading speed is generally about 150MB/s, good performance of solid-state drives can also reach 3200MB/s, why say that the computer installation of solid-state drives can solve all kinds of computer problems? System loading too slow can lead to the loss of system files, so that the computer will appear boot no boot black screen phenomenon, the computer into the operating system, load the hard disk software and system files interrupted, then the computer will appear blue disk and other phenomena, the system loading speed is too slow can directly lead to all kinds of data being edited data loss, some people are anxious, when the computer is running extremely unsmooth will lose their temper, and even drop the keyboard and smash the mouse.
The desktop computer can be directly retrofitted with an SSD
Nowadays, the price of SSD is very close to the price of cabbage, 1GB is about 0.6 yuan, 128G SSD is also dozens of dollars, 1TB capacity SSD price is also a few hundred yuan, the best performance nvme protocol 1TB high-performance SSD price is also about 700 yuan, after the computer is installed with SSD, the computer operating system will run smoothly, the system can also be smoothly loaded, and the opening speed and running speed of various types of software are immediately improved, which can greatly reduce the computer blue disk The risk of failure, such as crashes, black screens, and data loss, can save a lot of money needed to reinstall the computer operating system.
M2 interface SSD
There are two types of interfaces commonly used in SSDs on the market. The first is a 2.5-inch SATA interface, the second is the M.2 interface of the 2280 solid-state drive, we need to look at their own computer motherboard support M.2 interface when choosing an solid-state drive, if not supported, then choose the 2.5-inch SATA interface of the solid-state drive, desktop computers can be directly installed, the laptop can be the original mechanical hard disk can be removed to install the solid-state drive, if the mechanical hard disk does not want to be removed, the motherboard does not have an M.2 interface, that can be removed from the optical drive, buy an optical drive position bracket, and then put the solid state drive into the bracket, and then the bracket can be installed into the optical drive position (as shown in Figure 1).
