What is SSD Drive?

Introduction to SSD drives

A solid state drive, or SSD for short, is a type of hard drive made up of an array of solid state electronic storage chips controlled by a control unit. The storage unit may consist of FLASH chips, DRAM chips or both. SSDs have the same specifications, function, and usage as regular hard drives, and are the same size and shape as regular hard drives. They are widely used in military, automotive, industrial control, video surveillance, network surveillance, network terminals, power, medical, aviation, navigation equipment, and other fields.

The working temperature range of the chips is very wide: commercial products ranging from 0℃ to 70℃, while industrial grade products range from -40℃ to 85℃. Although the cost is high, they are gradually becoming more popular in the DIY market. Since SSD drive technology is different from traditional hard drive technology, many emerging storage manufacturers have appeared. Manufacturers only need to purchase NAND memory, and then match it with appropriate control chips to make SSD drives. The latest generation of solid state drives commonly use SATA-2 interfaces, SATA-3 interfaces, SAS interfaces, MSATA interfaces, PCI-E interfaces, NGFF interfaces, CFast interfaces, and SFF-8639 interfaces.

With the rapid development of the Internet, people's demand for data storage is constantly increasing. Many storage manufacturers have launched their own portable SSD drives, and there are also mobile solid state drives that support Type-C interfaces and SSD drives that support fingerprint recognition.

Advantages of SSD drives

High read and write speeds: Using flash memory as a storage medium, the read speed is faster compared to mechanical hard drives. Solid state drives do not require a magnetic head, and the seek time is almost zero. The sustained write speed is also very impressive, with most solid state drive manufacturers claiming sustained read and write speeds of over 500MB/s. The fast reading and writing speed of solid state drives is not only reflected in continuous read and write processes, but also in random read and write speeds which are the ultimate secret of solid state drives. This is most directly reflected in the majority of daily operations. There is also a very low access time. The seek time of the most common 7200 RPM mechanical hard drives is generally 12-14 milliseconds, while SSD drives can easily achieve 0.1 milliseconds or even lower.

Shock resistance: Traditional hard drives are disk type and store data on disk sectors. SSDs, on the other hand, are made of flash memory particles (such as mp3 players and drives), which mean they do not have any mechanical components. SSDs can still function properly even during high-speed movement or when tilted at an angle. Moreover, during collisions or shocks, they are less likely to lose data compared to traditional hard drives. As such, SSD drives have advantages over traditional hard drives.
