NVM Express Format

[Dan McLeran]

FYI, if this is a device which has never before been formatted then you 
would need to send down MODE_SELECT before FORMAT_UNIT if you want to do 
this via SCSI. I've never done it this way so I don't know exactly what to 
do.

I have tried using the Linux command "sg_format" but that does not work. Is there a NVM Express command that will accomplish this? If so, how would I go about using this command? My goal is to be able to have a method of purging the SSD in order to run performance tests on the drive.
