Correct boot option pmedia entry for an nmve SSD?

What is the correct pmedia option when the "Hard Drive" is an nvme SSD. For a traditional spinning disk HD it would be pmedia=atahd. Is there a new entry for nvme SSDs /
TIA

It really depends on how you want the save to work.

the pmedia= actually controls the pupmode used, for how Puppy works, in using the save.

pmedia=atahd
This tells Puppy to run in pupmode 12.
This tells the boot process and the save process, to handle the save in a mode, to directly write to it, at anytime something needs to go into the save.

You could use pmedia=ataflash or pmedia=usbflash
Run in pupmode 13.
This should boot using a save ramdisk for direct storage of stuff that needs to go into the save.
you move stuff (write into the actual save) by clicking on the desktop save icon, a set time to do it, or when you shutdown.
Controlled by settings in the Puppy Event Manager -> Save Session.

Pupmode 13 operation is best if you are concerned with how often writes are made to the save. Thus writes to the SSD.

SSD's do have a max number of write cycles, before they are suppose to start going bad.
Most have at least a typically up to 100,000 write cycles.
