Is there any advantage to upgrading the MicroSD card from 16 GB to 32 GB?
Can this additional space be utilized to prevent any system issues?
I plan on upgrading to an “Industrial” grade card since it has a wider functioning temperature range than the consumer grades, and just need to decide if 32 GB will make a difference or not.
Reliability. The new card is more reliable than the factory supplied card. Memory wise I haven't found a use other than lots of free space. Maybe a slight bit faster on boot. I picked a microsd with the fastest memory access speed I could find and I could only find a card with 128GB on sale. It's rated industrial or gaming speeds and temps. Works fine. I believe my system is more stable. I seemed to have more crashes with the factory 16GB. Now, almost none.
That's my experience.
With more memory you could download more programs for your LINUX os running on the raspberry PI Or use the space for downloaded research online. but then This machine really only has one purpose. Cache memory belongs in ram and on the NVME drive. They are fast. The system memory on the microsd is dedicated to OS programs. That's proper delegation and design.
What brand of microsd card did you purchase? I have been running my new Apollo2 for six days and it is 94.35% synced. It has crashed a few times during this process. It has shown usually 16/32 connections. My factory 1tb nvme card has 37% remaining space left. So, I will probably go to a larger nvme also.
