dd if=/dev/rdk0 of=/dev/null bs=1024k

^C93836+0 records in

93836+0 records out

# dd if=/dev/rdk1 of=/dev/null bs=1024k

57226+0 records out

So how do I increase read writes to my drive.. to I need to write with 1024k block.. but the server is going to be used as database and not file sharing.  Any tweaks you can recommend.. I am using gpt for configure the drive..
