Hi, All and @candide
My test MicroSD card is rather old, 2 GB one.
1) Strange, but rSD32 lib cannot be used - ESP32 MCU is rebooted at SD.totalBytes, but previous SD.cardSize works OK:
Any idea why ?
2) Regular rSD works (not fully OK writing, debugging yet), reads and writes, but found that each 100 text lines (20 bytes each) - are written during ... 6+ seconds !
It is very slow.
What are your writing speed results ?

I was trying to init with low frequency also, but in vain.
