I have two netPIs, and their writing speed seems to be different.
To measure speed on same condition, I re-installed firmware(V1.2.2.0) and deployed a container from the same image (hilscher/netpi-raspbian) on each netPI, however, the writing speed is different. One is about 13MB/s and the other is 18MB/s.
(I tested the writing speed with the command "dd if=/dev/zero of=benchmark bs=380k count=1k conv=fdatasync")
I want to know about this writing speed difference.
Could you answer the following questions?
It is hard to answer I guess, however, if you have any ideas about my questions, please let me know.
Best regards,

Could you answer the following questions?
- Is there any ways to check SD card conditions?
Since I am a beginner of Docker and Linux, I could not find the way to check SD card conditions. Is there any commands to check it?
(I could not find proper way to use badblocks command)
- Is this SD card endurance problem?
I suppose that this is SD card endurance problem.
Could you tell me any other factors that may cause this difference?
- In the case of SD card endurance problem, is there any way to deal with it?
- If this is not the case of SD card endurance problem, is there any way to deal with it?
- Could you tell me the write speed on factory-sealed condition?
The faster netPI is not so new. I want to know if the faster one is already deteriorated or not.
