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.
Boi that is great! Do you publish your data/experiences somwhere? And also did you throw some of the high/ultra endurance models in the mix (normally for video surveillance and stuff)? I had so many normal micro SDs fail for i dont trust them anymore and rather grab one of these…
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…
Let me know which is the best so I can buy it for my raspberry pi.
Reminds me of the u/spaceinvaderone video where he stress tests a load of usb sticks.
Do you have any temperature controls for this experiment? Seems that all that gear is heating the sdcards under test. It would be interesting to see their performance under temperature extremes, or at least under typical ambient operating temperatures.
If dashcams are any indication, they are mostly shit. Even the endurance cards don’t last as long as you’d expect.
I also have a boatload of these adapters and no practical use lol
I would put a fan on those card readers though to remove them as a point of failure👀… I’ve needed to backup 7 micro sd cards at a time for some shoots using a USB hub and damm do the readers get hot when copying a ton of stuff
That’s awesome. I can’t wait to see the results. That’s quite a collection of card readers, also. It will be interesting to see if they all survive, too.
Can you post your results when you find the best?
As co-workers have reminded me many times, 127 device per bus limit is not intended as a challenge.
What is the combined max writing speed to all the cards, does the usb max out? At what numbers? And what is the model of the hub?
Why cable manage a temporary setup (especially with zip ties)?
You are not stress testing anything here besides the Universal Serial Bus…
If you read the post, they’re testing for endurance, not speed.
The point seems to be a write endurance test mostly
Can you recommend reliable USB hub with at least 10 ports?
