Solid State Disk
Information Technology
Solid State Disk (SSD), or SSD for short, is a type of computer storage device that primarily uses flash memory (NAND Flash) as permanent memory. Solid State Disk consists of a control unit and a storage unit (FLASH chip, DRAM chip), and is widely used in industrial control, video surveillance, network monitoring, network terminals, navigation equipment and many other fields. Compared to mechanical hard disks, SSDs have higher read/write speeds, but they are also relatively costly. The new generation of SSD adopts SATA-III, PCIe x8 or mSATA, M.2, ZIF, IDE, U.2, CF, CFast interfaces.

Solid State Drives
There are two types of storage media for SSDs, one using flash memory (FLASH chips) as the storage medium and the other using DRAM as the storage medium.
Flash-based: Flash-based SSDs (IDEFLASH DISK, Serial ATA Flash Disk): use FLASH chips as the storage medium, which is also commonly referred to as SSDs, and can be made to look like a variety of models, such as laptop hard drives, microdisks, memory cards, flash drives, and other styles. The biggest advantage of this kind of SSD is that it can be moved, and the data protection is not controlled by the power supply, which can be adapted to various environments and is suitable for individual users. [1] Generally it erases and writes the number of times generally about 3000 times, to commonly used 64G for example, in the balance of the SSD writing mechanism, the total amount of data that can be erased and written 64G X 3000 = 192000G, if you are a perverted video king every day like to download the video to watch the end of the deletion of the daily download of 100G, then the number of days available for 192000 / 100 = 1920, which is 1920 / 366 = 5.25 years. If you are just an ordinary user to write the number of daily
