Crash hardened memory is a small category with a long qualification cycle. What separates suppliers is not the datasheet. It is how many units are in service, whether the testing was done by certified, accredited laboratories, and whether the supplier can still deliver against that certification in fifteen years.
DEUTA designs protected memory products specifically for data and video. Video products solve different engineering problems from data storage memory, and we build both.
Surviving the crash is the part everyone talks about, and for us it is settled ground: our housings are qualified to a variety of required standards — both the 1999 and 2013 editions of IEEE Std 1482.1, the FRA Appendix D criteria, and IEC 62625-1 where applicable. Building to whatever standard a project calls out is a known quantity.
The harder problem is the fifteen years before the accident. An event recorder writes kilobytes a minute at a stop-and-go pace. An image recording system writes several gigabytes an hour — continuously, at temperature, inside a sealed enclosure that cannot be fan-cooled. That load has to be absorbed without a gap in the recording. The file being written at the moment of impact has to remain readable after the power suddenly dies. The memory has to be exceptionally durable. And all of it has to fit inside a thermal budget the fire test has already set.
We solve those problems because we have already met them in service. A hardened enclosure, on its own, solves none of them.
