How long have we had SD Cards for them to still be unreliable like this? This is unacceptable.
- dleslie 8y agoNow you have good odds of purchasing a counterfeit. Doesn't seem to matter where you buy from, too. The consumer electronics market is a shit show.
- sneakernets 8y agoThis is exactly my fear. There is no quality control anymore.
- AlotOfReading 8y agoYou 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.
- bityard 8y agoThe problem is that SD cards were designed for portable storage of photos and music, which is a completely different use case than running an OS or database on top of them. They're being asked to do something they were not designed for, and then people get upset about it. They make high-endurance SD cards that have the same (or better) reliability as SSDs. These are what should be used in any Raspberry Pi that does some non-trivial amount of writing to the disk. Or boot from USB or Ethernet.
