Mechanical hard drive is the ordinary hard drive we use. It has large capacity and low price. Due to the rapid improvement in the performance of other components, mechanical hard drive appears to have poor performance. However, it is still the leader. When solid-state hard drive becomes popular, it will become history.
#It is better to install the system on a solid state drive because it is faster.(Recommended learning:PHP video tutorial)
Comparison of the differences between solid state drives and mechanical hard drives:
Advantages of solid state drives: no noise, read and write speed Extremely fast, anti-vibration, low heat, lightweight, etc.
Advantages of mechanical hard disk: large capacity and cheap price.
Disadvantages of solid-state drives: high price, small capacity, solid-state drives have a limited number of PE writes, so their lifespan is lower than that of mechanical hard drives.
Disadvantages of mechanical hard drives: loud noise, fear of vibration, high heat generation, and slow reading and writing speeds.
Solid-state drives are hard drives developed in recent years, but they are expensive, low-capacity, and very good in performance. Many enthusiasts install solid-state drives and ordinary hard drives (mechanical hard drives) into their computers at the same time; in Install the system into the solid-state drive, and install games, movies, music, etc. into the ordinary hard drive. Since the system runs on the solid-state drive, the system performance will be improved.
Solid State Drive, commonly known as solid state drive, is a hard drive made of an array of solid-state electronic memory chips. It is named because solid capacitors are called Solid in Taiwanese English. . SSD consists of a control unit and a storage unit (FLASH chip, DRAM chip).
The interface specifications and definitions, functions and usage methods of solid-state drives are almost the same as ordinary hard drives, and the appearance and size are basically the same as ordinary 2.5-inch hard drives.
Solid state drives have the characteristics of fast reading and writing, light weight, low energy consumption and small size that traditional mechanical hard drives do not have. At the same time, their disadvantages are also obvious. Although IDC believes that SSD has entered the mainstream of the storage market, it is still relatively expensive and has low capacity. Once the hardware is damaged, data is difficult to recover. Some people also believe that the durability (life) of solid-state drives is relatively short.
The main factors that affect the performance of solid-state drives are: main control chip, NAND flash media and firmware. Under the same conditions as above, the interface used may also affect the performance of the SSD. The mainstream interface is SATA (including 3Gb/s and 6Gb/s) interface, and there are also SSDs with PCIe 3.0 interface.
