What are the types, advantages and disadvantages of computer hard disks?

Ssd has the advantages of fast reading and writing speed, stable performance, low heating, low power consumption and no noise. Because there is no mechanical part, even if it is used for a long time, the probability of failure is relatively small. The disadvantages are obvious, such as high price, small capacity, and no cost-effective advantage in front of ordinary hard disks. At present, mainstream SSDs rarely exceed 100g G.

By the way, sata is just an interface, and most SSDs also use sata interfaces. When you say sats hard disk, you should mean ordinary hard disk, just using sata interface.

So the advantages and disadvantages of ordinary sata hard disk are actually good, contrary to ssd. Large capacity and cheap price. At present, the capacity of a disc is between 320g- 1.5t, and the price is about g0.7 yuan per g, which can be said to be cheaper than dvd burning. However, the use of ordinary hard disks will generate noise and heat, and the power consumption is also large. After a long time, it will cause mechanical loss, and the failure probability is much higher than ssd.

In addition, at present, ssd is mostly 2.5 inches, which means it is suitable for notebooks, some quasi-systems and mobile hard disks. If it is an ordinary desktop, it will be a little troublesome to use.

When P.S. goes back upstairs, you have to copy and find some new materials. What are those old things for? Now you find a 1.8 inch ssd in the market for me to see.
