SSD Industrial Temperature- Why Is the Operating Temperature Significant?
For industrial applications, like in the aerospace industry, an SSD could indeed be exposed to significantly fluctuating temperature ranges. Industrial SSDs are an appropriate choice for fields in which ruggedness and durability are crucial. Here is a closer look at operating temperature considerations for industrial SSDs.
How Temperature Affects Data Retention
Each memory cell in a solid state drive has a floating gate, control gate, drain, and power source. An oxide insulation layer surrounds the floating gate to trap electrons inside it. But eventually, the insulation layer can become weakened, allowing electrons to leak outside the floating gate and back to the substrate. The leakage of electrons changes the voltage level, which can raise the risk of a bit error, and eventually, can lead to a system error. Temperature can affect the strength of the oxide layer, but industrial grade SSDs are built to withstand high operating temperatures. This allows these SSDs to provide reliable data retention, even in extreme environments.
How SSDs Minimize Heat Output
In addition to having a wide operating temperature range, industrial SSDs are designed to operate with lower heat output than traditional hard disk drives (HDDs). HDDs have a mechanical arm that moves to read information. One of the primary differences between HDDs and SSDs is that the latter device doesn’t have a mechanical arm and lacks any sort of moving parts. Since they don’t move, SSDs don’t generate the heat output that is characteristic of HDDs during operation.
