Characteristics of Solid-State Storage Devices and Their Applications in Industrial Control Computers

Characteristics of solid-state storage devices

Resistance to shock and impact is one of the characteristics of solid-state storage devices. Because they use flash memory chips exclusively, there are no mechanical parts inside SSDs, so even in situations where they are moving at high speeds or even flipping and tipping, normal usage is not affected. Moreover, the possibility of data loss due to accidental dropping or colliding with other objects is minimized.

When working, solid-state storage devices operate silently (with a noise level of 0 decibels due to the absence of mechanical motors and fans), generate little heat, and dissipate heat quickly.

Compared to traditional storage devices, solid-state storage devices are lighter in weight, making them more portable. They are not limited by power supply and are suitable for use by individual users in various environments.

Application of solid-state storage devices in industrial control systems

As we know, industrial control systems differ from ordinary PCs in terms of the architecture of their motherboard, the design of their chassis, and the scalability of their industrial motherboards, all of which are strictly implemented according to industry standards. However, as a control system that operates in harsh environments for long periods of time, all data processing has to go through CPU calculation and read/write to the hard drive. Storage has been a challenge for industrial control manufacturers because traditional mechanical hard disks, due to their inherent mechanical parts, operate in high-temperature, humid, and vibrating environments that can easily cause hard disk failures, leading to a system crash that can affect the efficiency of the entire control system.

Because SSD drives use NAND flash memory, they are completely semiconductor-based and have no mechanical parts. They meet military-grade standards for shock and impact resistance, making them fully suitable for use in harsh industrial environments.

With a highly extended operating temperature range of -45°C to 85°C, a random access speed of more than 30MB/s, and an MTBF time of more than 2 million hours, SSD drives not only ensure normal operation of IPCs in industrial environments but also significantly improve the performance of the entire control system, making it more stable and reliable.

SSD drives are the same size as traditional mechanical hard disks, come in several common sizes such as 1.8 inches, 2.5 inches, and 3.5 inches, and use IDE or SATA interfaces that are fully compatible with PC hardware. They support various operating systems such as Windows9X/Me/NT/XP/CE/Vista, MAC, Linux, and Unix. Depending on the user's data processing requirements, storage can range from 1GB to 1TB and even larger capacities in the future. Raid card technology can be used to create a solid state disk array and increase the storage capacity of the entire system.
