Feature: Embedded
Key considerations for selecting the optimum SSD for an industrial or embedded system

hoosing the correct Solid State Drive (SSD) for your industrial computing or embedded system application is key to maintaining a successful, reliable installation. Industrial
and embedded computing applications are as varied as they are complex, but fortunately this variation is also reflected in the multitude of SSDs available on the market. With various form factors, durability
and security features, the selection does not always boil down to price, and choosing which SSD is right for your single board computer or fanless PC can mean the difference between an installation truly fit for purpose, or one with the potential to under- deliver, or worse, completely fail.

Form factor defines features Form factor is perhaps the first consideration when choosing an SSD for an industrial or embedded computing application. It’s not just about space; with different form factors come different interfaces, which provide various features that may or may not be applicable to your industrial or embedded computing installation. For instance, if we look at the 2.5” SSD,
which is arguably the most commonly available in ready-to-go integrated embedded computers, this offers a number of benefits: due to its ubiquitousness, availability is normally never an issue, and these large-capacity drives are easy to install. Tey support most (or even all) flash
technologies, such as TLC, MLC and SLD, oſten support an extended temperature range (from -40°C to +85°C), and offer options for resilience technologies, which protect data and operating systems from power instability or outages. If you would prefer your SSD to be
installed using a more discreet method, perhaps in an effort to reduce overall system footprint, or are using an embedded computer board with a single power source, then MSATA or M.2 (MSATA’s updated equivalent) could be the best option. Tese drives fit parallel with the board, taking their power directly from the SBC/ embedded PC, whereas 2.5” SSDs require separate cabling for data and power, which take up valuable room in embedded
