The write speed on Windows is 17-20 MBps but on all Linux OS's copying a file to the sd card jumps instantaneously to ~90% and stays there until it says "finished" without any speed readings.
I have tried three different UHS 1 32gb cards and they all perform the same.
What could be behind this? How to get full speed out of the reader on Linux?
This has been reported here, and also in the link therein, but I don't recall a solution was ever found.

I will test it over the weekend

This sounds like something in the BIOS's ACPI tables, most likely the DSDT (Differentiated System Description Table). IIRC the DSDT can contain OS-specific profiles/configurations, which can explain why the Ricoh's PCI ID changes to E822 when booting to Linux.
