My rig that’s stress testing 37 microSD cards simultaneously. (alien.top)

So I took it upon myself to answer the question of “what are the best and cheapest microSD cards out there?” This includes evaluating whether they’re fake flash, how well they perform, and how many read/write cycles they can endure before they start failing. So far I’ve tested four to the point of failure, I have 37 being tested right now, and I have 21 more waiting to be tested.

Sorry for the horrendous cable management — I have cable ties on order.

Which header you're using? I had bad luck with readers being pretty wonky.

Would be interested in results, my SBC cluster died on a bunch of samsung EVO cards turning read-only.

Or rather PRETENDING to be read-write by ignoring writes, which made very funny debugging session where the OS started crashing the moment write cache in RAM ran out and it tried to read the data it wrote...
