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.
Can you post your results when you find the best?
FYI, OP doesn’t care about the data or whatnot. They just really enjoy torturing hardware.
*taps nose*
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?
You are doing gods work, salute!🫡
Can you recommend reliable USB hub with at least 10 ports?
Raid 0 that mess just for fun lad.
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.
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

As co-workers have reminded me many times, 127 device per bus limit is not intended as a challenge.
“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
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,
Let me know which is the best so I can buy it for my raspberry pi.
I use h2testw, did you find any outright fakes (died first pass?)
