I reformatted the card in the phone when I first put it in.
I have re-run the accurate test just now and only got 74.30 mbps read and 27mbps write
Re-ran the test straight away (bearing in mind the phone needed to reboot between the write and read in the first test) and got 60mbps write and 76.79 mbps read.
Re-ran again and got 76.79mbps read and 60.24mbps write.
Not sure if uptime, free RAM or other open applications has an impact on write performance. Will try again later and see if it does.
On 10H at the moment. My impressions is that with each new version the speeds improve. Memory card only has 16GB free out of 64GB.
