Code:Standard driver: Avg. Write 2.7 MB/s Avg. Read 3.7 MB/s Avg. hdparm 9.48 MB/s (#core_freq=500, #force_turbo=1)
Standard driver: Avg. Write 2.4 MB/s Avg. Read 2.5 MB/s Avg. hdparm 8.18 MB/s (core_freq=500, force_turbo=1)
New SD driver: Avg. Write 6.3 MB/s Avg. Read 19.8 MB/s Avg. hdparm 20.79 MB/s (dtoverlay=sdhost, core_freq=500, force_turbo=1)
Are the old driver numbers slower because of the warnings introduced in latest build? Does the previous build have better numbers for old driver?
In general I'd expect about 18MB/s for old driver and just over 20MB/s for the new one (for continuous read, like hdparm -t).
