You can have high capacity, low cost, or reliability. Pick 2.
Consumer cards choose capacity and cost, because that's what sells. Industrial SD cards pick capacity and reliability, but cost at least 4x more than similar consumer cards due to inherent tradeoffs in the hardware/firmware design.
- dpedu 8y agoAre they though? I looked on Amazon; the price difference between a 'regular' 32GB microsd and a 'high endurance' card of the same capacity is $3 (7.99 vs 10.99).
- AlotOfReading 8y agoConsumer high endurance cards are still MLC or TLC. They're better than regular consumer SD cards, but still not what you'd consider ideal reliability. Industrial cards are better QC'd and use more reliable (but less dense) SLC, as well as various smaller changes to operate reliably in extreme conditions. I'm sure some of it is industrial product markup as well, but the technology is fundamentally more expensive.
