High Performance from Industrial SSD (part 1)

The variety of Solid-State Drives (SSD) drives on the market can lead to confusion when researching & purchasing systems for industrial applications.  It is important to consider that many SSD’s are not suitable for industrial applications.  To better understand the differences, this article will explain how only Industrial-grade SSD’s are specifically suited for industrial applications.

Consumer Grade

Designed for the consumer laptop market, consumer-grade SSD’s are primarily optimized for the lowest cost per gigabyte.

Most products for this market are designed with Multi-Level Cell (MLC) technology. MLC flash technology enables lower cost per gigabyte while sacrificing durability.  Consumer Grade SSDs are the most visible in the market since they are optimized for the high-volume, low-cost per gigabyte applications such as laptop computing and gaming.

Commercial Grade

These drives are designed for applications that require more reliability than standard HDD’s and consumer SDD’s, but will only operate in stable environments, thus not too demanding in terms of ruggedness and reliability.

Typically these products are designed with Single Level Cell (SLC) technology, although in the future they may also be offered with MLC technology.

Industrial Grade

Industrial-grade SSD’s are designed and manufactured for extremely demanding applications that require ruggedness and reliability.

Products in this category will be offered with Single Level Cell (SLC) technology due to its superior performance, reliability and endurance.

Industrial Grade storage solutions are required for applications that:

  • Operate in harsh environments, in terms of shock, vibration, humidity and temperature
  • Are located in remote locations with difficult, costly access by service engineers
  • Have extremely high reliability demands (i.e. mission critical)

For these applications, a true ‘Industrial Grade SSD’ that is designed, tested and manufactured for these applications will be the product of choice .

Industrial Grade SSDs set themselves apart from their Commercial Grade counterparts throughout all aspects of the product life cycle. During design phase, Failure Mode and Effects Analysis (FMEA) procedures are implemented, which qualify components for industrial standards. The design verification stage also includes thorough design verification testing, margin testing, environmental testing on operational devices, Highly Accelerated Life Testing (HALT testing) and regulatory compliance certification. During manufacturing, each individual drive is tested, including an 8-hour burn-in test to eliminate early device failure in the field. Finally, ongoing quality assurance methods (such as beta testing and closed loop corrective action through failure analysis procedures) are standard testing and manufacturing practices.
