Benchmarking with dcfldd
Dcfldd doesn't print the average speed in MB/s like good old dd does but with time you can work around that.
Time the run clearing the disk:
# time dcfldd if=/dev/zero of=/dev/sdX bs=4M 18944 blocks (75776Mb) written.dcfldd:: No space left of device real 16m17.033s user 0m0.377s sys 0m51.160s
Calculate MB/s by dividing the output of the dcfldd command by the time in seconds. For this example: 75776Mb / (16.4 min * 60) = 77.0 MB/s.
