That works!

Tested on i.mx25 architecture with sdhci-esdhc-imx driver.

Here are some time measurements.

#time dd if=/dev/zero of=test bs=1MB count=1
real	0m0.614s
user	0m0.000s
sys	0m0.132s

#time dd if=/dev/zero of=test bs=1MB count=4
real	0m1.328s
user	0m0.000s
sys	0m0.390s

#time dd if=/dev/zero of=test bs=1MB count=8 
real	0m3.922s
user	0m0.000s
sys	0m0.747s

#time dd if=/dev/zero of=test bs=1MB count=16
real	0m8.162s
user	0m0.009s
sys	0m1.419s

#time dd if=/dev/zero of=test bs=1MB count=32
real	0m15.725s
user	0m0.000s
sys	0m2.758s

Thanks for the help.

Kind regards,
Benjamin Beckmeyer
