The difference between a computer solid state hard drive and a mechanical hard drive
Now computer is not equipped with at least a 128GB solid-state hard drive, and it is a shame to sell it. We can say that solid-state hard drives are already a must-have product for installation, and price is not very high. There are many cheap solid-state hard drives. Internet, let's talk about it together.
Benefits
1. Compared with mechanical hard drive, solid state hard drive is much smaller and weighs very little. The SATA interface solid state drive is only 2.5 inches, and M.2 interface is even smaller, while the desktop mechanical hard drive is 3. 5 inches, so use a solid state hard drive. If it is, it can save a lot of space on some mini hosts or thin and light laptops, for example.
2. Solid state drives are similar to U disks. They use flash memory chips to store data, so there will be no noise. Mechanical hard drives can often make noise after a long period of use, especially for laptops.
3. The mechanical hard drive finally has 7200 speed, but read speed is still not as good as most solid state hard drives. The read and write speed of an SSD using SATA3 interface is typically 3-5 times that of a mechanical HDD using M.2 NVME. Protocol solid state hard disk can reach ten times or even higher read and write speed of a mechanical hard disk. This is clearly seen in speed of downloading pictures when playing games.
4. The power consumption of solid state hard drives is much less than that of mechanical hard drives, so heat dissipation is lower. As for energy saving, it can really save, but not much. However, on laptops, small heat generation is best point. After all, laptops dissipate heat. But a big problem.
5. The mechanical hard drive cannot be dropped due to its mechanical design, while solid state hard drive is generally not easy to be damaged by impact or shaking. Of course, it is not easy to be damaged. bad.
While there are many advantages, there are actually many disadvantages. However, compared to benefits, these disadvantages are also minor, such as capacity and price issues. The larger SSD capacity, higher price increase. If it is a mobile SSD, it will be more expensive. In terms of lifespan, SSD hard drives do have a shorter lifespan than mechanical ones, but in normal times, there is no need to consider this issue, and it can definitely be used for five or six years.
In terms of data recovery, mechanical hard drives are easier to recover from data loss, but solid state drives are next to impossible.
