I developped a datalogger that streams 4 analog channels sampled at 1 Khz using a compactDAQ system.
I start a new file every hour, each file is about 56meg
So the actual write speed is 16 KB/sec.
Why does the logging freeze using SD cards with write speed 4 MB/sec and not using SD cards with write speed 15MB/sec?
Am I missing something?
