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.
That actually looks cool. Are you looking to make sort of an article or blog post and publish the results?
I’m actually working on a script for a YouTube video right now. Might also make a blog post about it, I dunno.
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
“Stress testing micro SD cards” is just a funny way of saying "Prematurely burning up a bunch of SD cards.
Well, yeah but you want to know which one burns the slowest
You are doing gods work, salute!🫡
As co-workers have reminded me many times, 127 device per bus limit is not intended as a challenge.
Can you recommend reliable USB hub with at least 10 ports?
You are not stress testing anything here besides the Universal Serial Bus…
The point seems to be a write endurance test mostly
If you read the post, they’re testing for endurance, not speed.
Raid 0 that mess just for fun lad.
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)?
Have fun. Where I see this beating out other options for low access / possibly cold storage is you could make it incredibly dense in terms of tb/kg and tb/cm3. It would make a fun challenge and be damn near impossible to maintain 🤣
Flash is… not great for cold storage from what I’ve read. Electrons eventually leak out and your data is gone. Well, unless you put it in freezer
Fun fact: JEDEC specification for commerical flash only specifies year of retention as minimum at 30C and much lower at elevated temperature

FYI, OP doesn’t care about the data or whatnot. They just really enjoy torturing hardware.
*taps nose*
I use h2testw, did you find any outright fakes (died first pass?)
Not sure SD’s are competitive for performance / durability but it’d be interesting to see (presumably) how much lower the power consumption is, especially if you can disable / enable the usb port they’re connected to on demand for something like media storage where an extra second or so startup time isn’t an issue,
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…
