Tonverk SD Card Performance Test (Stock microSD vs Verbatim SD)

Interesting follow-up:

Another Tonverk user tested a Samsung card with even better random read performance and reported almost identical results for:

– Power On → Factory Project Ready

– Factory Project + all samples into RAM

So it might indicate there’s a performance ceiling somewhere in the system once a certain SD speed threshold is reached.

Curious what exactly becomes the bottleneck at that point — controller, filesystem, CPU, internal buffering?
