I wonder if you have noticed that the mobile hard disk is a product that we are familiar with every day, and it is being quietly eliminated. I have to say that the solid state disk is really a good thing. I remember that when the solid state disk first appeared, the old host computer was completely saved. Everyone replaced the mechanical hard disk with the solid state disk, and the boot was directly turned into the second boot from the previous turtle speed, The speed of SSDs has greatly improved the overall performance. By this year, the price of SSDs has also been lowered, and it has also driven the market of mobile SSDs. How should we choose the mobile SSD?

There are three main elements to determine the performance of the SSD, including the transmission bus, data protocol and physical interface. It seems that the selection of the SSD is very simple, but if you want to choose a good HDD, you need to have sufficient knowledge of the SSD. As a result, many friends will struggle. How to choose SSD? Xiaobai usually chooses particles for pedestrians with limited capacity. In fact, when purchasing a SSD, the two should be combined to make it more practical.

Most people think that they should choose a hard disk with a large capacity. The larger the hard disk, the better. Because the larger the capacity of the hard disk, the faster the computer will run. The simple principle is the same as that of mechanical hard disk. If the capacity is large, the space will be larger, and more information can be saved, so as to speed up the running performance of the computer. In fact, those who really understand SSD are different from mechanical HDD, and there will be great differences. Insiders choose SSDs, considering more particles and master control. Because of the particle composition of SSDs, the performance of SSDs is determined.

The better the SSD particles and the master, the faster the SSD will run, and the better the performance of the computer will be. Generally, the particles of SSD are mainly divided into four types: slc, mlc, tlc and qlc. In terms of performance, SLC is relatively good, and the price is also high. Qlc is the cheapest. In fact, the choice of solid state disk is very simple. No matter what brand and hard disk interface, if you decide on the size and granularity of the hard disk you want, you can choose a hard disk that is suitable for your computer.

In terms of design, there are usually many important data that need to be saved. It is recommended that these data be backed up to other storage separately, such as the small storage box class that supports RAID1. As the SSD is not a place for long-term data storage, it is recommended to use the SSD area as a work area rather than a long-term storage area. Like SSD, there are three common interfaces: MSATA, SATA and M.2. SATA interfaces are the most common, and traditional 2.5 inch SSDs are basically SATA interfaces. According to the different flash memory particles, it can be roughly divided into SLC, MLC and TLC. Normally, computers made of TLC can also meet the service life of 3-5 years.

In general, SSDs are very good in terms of both read and write speed and other performance. Mechanical hard disk is incomparable. If you don't think you can choose solid state disk, you don't need much knowledge of hard disk. It is recommended that you select the SSD according to the above two combination methods. I hope it will be helpful to you!
