What does the "dd"ing of an SSD do?
Aerospike recommends that prior to using an SSD for the first time, that you clear the SSD. Use the following command (you will need roo/sudo privileges)
sudo dd if=/dev/zero of=/dev/sdx bs=128k &/
Here “sdx” is the device of the SSD in question.
This will zero out the drive and make sure that any data there has been cleared out.
You can run these commands in parallel for multiple SSDs.
