Robustness of SD card vs eMMC in case of power outage
-
There are a few discussions regarding SD card corruption, e.g. SD Card fails after current cut. In that thread @Martin-Kudláček mentions an "upgrade" to eMMC as a potential solution - e.g. using Patron instead of Neuron devices. In principle this makes sense, but I'd like to get clear on just how much of a difference this makes.
The eMMC modules in Patron devices are based on MLC technology, which would in theory be less robust than a high-quality SD card based on SLC or pSLC technology (link). But maybe the fact that it's a soldered-on eMMC module makes things better? Maybe the eMMC controller is better/smarter?
I've looked around the internet but did not find great comparisons of SD cards vs eMMC in this context. The general narrative is that eMMC is quite similar to having a "soldered-on" SD card. This often leads to better read/write performance, but it's not clear whether there's improved robustness in case of power outage. Any info from the community would be welcome!
