Industrial SSD Storage: SLC vs. MLC

There are several advantages to incorporating Solid State Hard Drives (SSDs) into your next Industrial Computer System:

2U Industrial Computer

  • Environmental Ruggedness
  • Vibration Tolerance
  • Less Heat Generated compared to Traditional HDD
  • Low Power Consumption
  • Shorter Access Times, Faster Boot Times and Application Launches
  • No moving parts

It is important to understand that SSDs come in two types of Flash Cell Configurations: Single-Level Cell (SLC) & Multi-Level Cell (MLC).

  • SLC is the preferred SSD for Industrial Applications, and offers the highest MTBF
  • MLC offers higher capacities and lower cost
