The USB interface and Flash Drives have been around since the mid-1990s. In fact, USB Flash Drives are so common, little thought is given to what their made of.
The “guts” of the USB Flash Drive determine if it is not reliable for much more than a single use - all the way up to - a full-blown Industrial USB Flash Drive for mission critical applications.
The purpose of this article is for OEM Designers to look at the usage model of their embedded OEM designs which use a removable USB Flash Drive.
For requirements where there is a need to send out an update once in rare time frame, which will be loaded to the system and then disregarded, a consumer USB Drive with extremely limited endurance cycles, ruggedness and life expectancy may be acceptable.
An SLC USB Flash Drive is highly recommended for an application in a harsh environment where the USB Flash Drive is:
- Subjected to High Shock & Vibration
- Used to run an Operating System
- Constantly written with Data Logging Files
- Exposed to Temperature Extremes
- Subject to being Jarred or Hit
- Required to have a Long Life Cycle
- Carrying Critical Data to and from Site
Since Industrial Grade Flash Storage Devices are orders of magnitude more reliable than the Consumer flash products, they can provide a solid solution for the OEM Designs dealing with the issues above.
Bottom line, it’s a good idea to review your usage model prior to making your selection of USB Flash Drive product and supplier. The vast majority of USB Flash Drive applications can get by with a consumer part, but for more important data and crucial embedded OEM requirements, a robust Industrial UFD is a more fitting solution.
