The difference between mobile solid state drive and mobile hard drive
With the increasing development of science and technology, people's requirements for equipment for storing data are becoming more and more stringent, and mobile storage devices emerge in endlessly, such as USB flash drives, mobile hard disks, mobile solid-state drives, etc. I believe everyone is familiar with USB flash drives, but what is the difference between a mobile hard drive and a mobile solid-state drive? Which is better, mobile hard drive or mobile solid state drive?
1: Mobile hard disk
Mobile hard disk refers to a traditional mechanical disk as a storage medium, used for computers. It is a storage product that exchanges large-capacity data between devices and pays attention to mobile portability.
Advantages: It has the characteristics of large capacity and low price, and is convenient for storing large amounts of file data. (Recommended learning: webfront-end video tutorial)
Disadvantages: Poor earthquake resistance, physical bad sectors may occur when subjected to collision, head friction or strong vibration. Moreover, the size is not small enough, it is not user-friendly enough to carry when going out, and the traditional speed is also slow.
2: Mobile Solid State Drive
Solid state mobile hard drive generally refers to a solid state drive composed of NAND Flash. It does not have a mechanical structure. , but uses the characteristics of NAND Flash to perform read and write functions in the form of block writing and erasing.
Advantages: Mobile solid-state drives do not use magnetic heads and can read and write quickly. The reading and writing speeds are faster than mobile hard drives. The reading and writing speeds are usually more than 4 to 5 times that of mobile hard drives; it uses flash memory. Made of particles, it has strong anti-shock buffering ability, is not afraid of falling or shock, and has multiple protections for data security; and the size can be very small and light, making it more convenient to carry out.
Disadvantages: The price is more expensive than traditional mobile hard drives.
Comparing the advantages and disadvantages of the two, it can be clearly seen that mobile solid-state drives have more advantages. In addition, the entire solid-state drive market is on a downward price path in 2019. We should focus on mobile solid-state drives. On the hard drive.
