What happened
A three-year microSD card torture test wrote 133 petabytes across 351 cards, running them to failure. SanDisk stood out negatively, with 6 of the 7 SanDisk cards tested failing before the end of the study.
Why it matters
If you deploy Raspberry Pi, IoT, or edge devices using microSD for storage, this data suggests avoiding SanDisk microSD cards for write-heavy workloads and instead selecting brands with better endurance in this dataset. Builders running logs, databases, or AI inference on SD-backed edge devices should factor failure rates into hardware procurement.
Discussion angle
For Malaysian builders running edge or IoT projects on microSD-backed Pi clusters, which brands and capacity tiers have held up in local heat and humidity, and does this SanDisk failure pattern match field experience?
