Thread: Poor throughput when using dd command


when use following command overwrite drive zeros:

###warning: command designed irrecoverably destroy data###
code:
sudo dd if=/dev/zero of=/dev/sda
i throughput of 20mb/s. hdd should able write maximum speed of 100mb/s

why writing speed lower? there way increase throughput (writing speed)?

kind regards,
aef

small bump. somebody's gotta know answer.

generating zeros can't hard task cpu , if disk able write @ higher speeds, why doesn't it?

hello! i'm trying setup software raid on server, fail @ first step: code: root@sandnabba:/root# mdadm -c /dev/md0 -c512 -l5 /dev/sdc1 /dev/sdd1 /dev/sde1 mdadm: no raid-devices specified. what doing wrong!? are sure -c equivalent --create? also, think need space after -c , -l options, value shouldn't command, or should have = between. @ man pages mdadm , double check spelling.
