Designing Rugged Storage Devices for All Conditions

Most SSDS are internal and many external accessories remain largely in place. Even devices designed to be portable may have limited protection. However, sometimes users need something a little more rugged. Luckily, there are standards for this, which help determine how endurable the device is - that is, how much punishment it can handle. For example, an enclosure may be rated to survive a one-meter fall, as when dropped, or be shock- and vibration-resistant.

A common standard is the Ingress Protection Code, or IP Code, which gives an idea of a device’s level of protection. This comes in primarily two areas: solid or particle protection, and liquid or water protection. The first digit of the code can be from 0 to 6, that is no protection to complete dust protection or dust-tight. The second digit can be from 0 to 9K, or no protection to close-range, high-pressure, high-temperature spray protection. Other ratings are optional, but code allows for a standardized method of testing.

We sell not one but two enclosures designed to be water resistant and rugged, respectively. Both enclosures are rated IP67 which means they are dust-proof and are able to withstand at least one meter, or 3.3 feet, of water depth. The rugged enclosure additionally is tested to survive a one meter or 3.3-foot drop, thanks to its ruggedized bumper. We also sell a portable SSD, the Rocket Nano Rugged SSD, which meets IP67 requirements and can survive a one meter drop.
