Alright so let me start this by saying that where-ever i look i see that MicroSDs are not reliable at all or less reliable than any other storage media, which im pretty sure is true.
I've done a lot of research on the topic and do know about the NAND technologies being different (SLC/MLC back in ~2012 to TLC and QLC in 2024) and the differences of reliability of those, differences in Error Correction (BCH, LPDC), controllers, channels etc.
But all i managed to get is theoretical or manufacturer stated data or TBW's which tell me only the theoretical reliability not the practical one, i also don't have the time to test those MicroSDs (Cause doing genuine testing for long term reliability would logically take years)
On the flip side i had older MicroSDs survive over a decade with only minor corruption and hence my questions:
How reliable long-term are modern, High end high capacity MicroSD's (like the Samsung Pro Ultimate, Sandisk Extreme Pro or Sandisk Max Endurance)?
How long do these cards last practically (data retention) before the data corrupts?
Huge thanks to any and all answers, if i got something wrong also huge thanks for any and all corrections
