I have managed to install ubuntu on a 128GB SD card (class 10) which dual boots with windows 10. However, ubuntu works like an old guy. It comes up so slowly. It tends to halt and overall very slow function. And the bigger problem is that the wifi connection disconnects every two minutes.Does this slow function mean that it is a bad idea to install ubuntu on a SD card or it means that there is something wrong somewhere?Here is the rw speed of the SD card:dd if=/dev/zero of=/tmp/output bs=8k count=10k; rm -f /tmp/output10240+0 records in10240+0 records out83886080 bytes (84 MB, 80MiB) copied, 0.219472 s, 382 MB/s
Why ubuntu is so slow on the SD card?
