Thanks for the numbers. OPi ONE means H3 which means USB2.0 sequential transfer speeds bottlenecked by host implementation (~35MB/s with legacy, ~40MB/s with vanilla kernel if UASP can be used -- I haven't found any thumb drive so far supporting that). It should also be noted that benchmarks with just 10 MB file size might not tell the truth since many USB thumb drives are prone to throttling. They perform nice for 2-3 minutes and then drop down to laughable performance numbers (I've seen thumb
