  Oof, pretty pricy, huh. EDIT: I see in other comments that they're worth it, so they're a great option for when I need reliability at a premium, thanks!

  Oh yeah, I recommended these in the past and just mentioned them again in another comment on this thread :) 4GB is enough for most Pi projects, and <$20 premium is worth never needing to worry about SD reliability to me. My understanding is they use multi-level cells, which are far less expensive than true industrial grade single level cells, but they only write a single value to each cell, increasing the reliability significantly.

  Industrial grade AMLC, for example from this reseller and brand, haven't let me down yet. Other HN users have a similar experience. The downside is the price. Delivery was one day from Springfield to The Netherlands but had to pay duties. Which is like a total opposite of China: bad quality, cheap, slow delivery, but no duties
