A solid-state drive is composed of a control unit and a solid-state storage unit. The interface specifications, defined functions, and usage methods of industrial-grade solid-state drives are the same as those of ordinary hard drives, and the product shape and size are also consistent with ordinary hard drives. Because industrial solid-state drives do not have the rotating media of ordinary hard drives, they are extremely shock-resistant. Solid-state hard disk, the full name of solid-state drive, solid-state hard disk is basically the same as ordinary hard disk in shape and size. According to the use environment and scenarios, it can be divided into industrial-grade solid-state drives and consumer-grade solid-state drives. The biggest difference between the two is reliability and lifespan.
Consumer-grade solid-state drives are generally used for commercial or personal applications and are used in general environments. Therefore, they do not have high requirements for the use environment. The shelf life is generally one year, and the operating temperature is generally 0°C to 70°C. The main competitive advantage is the read and write speed. Many consumer-grade solid-state drives advertise read and write speeds exceeding 500MB/s per second, which is a huge improvement over mechanical hard drives.
The main advantages of industrial SSDs over consumer grades are reliability, durability, and stability. The most important of these is the working temperature. Generally, industrial-grade solid-state drives are used in various harsh environments, such as high temperature, high humidity, low-temperature environments, outdoors or special industries, so the applicable temperature of industrial-grade solid-state drives is generally -40°C to 85°C. Industrial-grade solid-state drives generally use MLC particles, while most of consumer-grade ones are MLC or TLC, so the lifespan of industrial-grade solid-state drives is much longer than that of consumer-grade ones. The general shelf life is 5 years, while consumer-grade ones generally have a one-year year time.
In terms of reliability and stability, industrial-grade solid-state drives also have an advantage. Industrial-grade solid-state drives protect user data from errors to the greatest extent, and may add some other functions, such as accidental power-off protection and data encryption. There are also functions such as shock and drop resistance.
Of course, although industrial solid-state drives have many advantages, they are naturally much more expensive than consumer-grade solid-state drives. Our personal use of consumer-grade solid-state drives can meet our needs. It is better to use industrial-grade solid-state drives for industrial or harsh environments, which are more secure.
