Do you think flashing Mobian to the eMMC will increase performance? only theoretically? or people are experiencing a huge change?it depends on the performance characteristics of your microSD. In the past they were optimised for sequential access to relatively large media files (audio, video, photos) which compromised performance accessing small files scattered around the place. Some makes and models were more compromised than others. More recently the App-rated microSD cards have appeared, and they put more emphasis on decent performance with those small files as that's what apps, or an OS, tend to access more. With an A1 rated Sandisk Ultra 128GB card I think there's a moderate improvement moving to eMMC, but I don't have any numbers to put on it.
Probably you guys have more objective tools to compare performance.
I did a small comparison. I flashed same Mobian Image (20200809) in microSD and eMMC.
Comparision was only based on booting time, firefox loading, and then opening cnn.com
I got very similar results for emmc or microSD (Scandisk 128gb class10):
Booting time was 25seconds average from eMMC vs 31 seconds average from microSD
Firefox loading 12 seconds with eMMC (I tried 5 times) vs 12 seconds (also 5 times)
Cnn.com loading 23 seconds vs 23 seconds (both 5 times)
So, I guess it does not matters using eMMC or microSD? is there a situation where it should matter?
