They are dirt cheap already... just check comparable boards on the market.

Hello, I am wondering about speed test result read-write in MB/s on USB 3.0 with external storage. I have an Orange pi PC2 where I have around 21-23MB/s. I would like to replace my device to Orange pi 3 if speed around 100MB/s. Thank you!

Android 7.0, Ubuntu Server /Desktop (with or without EMMC version), Debian Server /Desktop (with or without EMMC version), Shcematic, Mechanical Drawing, as well as Linux Source Code have been uploaded to our website: http://www.orangepi.org/downloadresources/

It is about 40MB

Will work for One Plus and Lite2?
