Area-51 R3, adding second SSD

I searched You Tube and learned about TinyTools. It was free and did a great job cloning my original SSD to the new SSD. I had thought that the original SSD and HDD were on the same SATA cable. But when I tried disconnecting the SATA cable to see if the new SSD would boot, I found the original SSD still online as C:. So, I had to find the C: drive. I found a video on YouTube that explained how to remove the NVIDIA GeForce XT 745 video card: Just remove the two screws and lift it straight up (it is attached to a riser board which plugs into the mother board). After removing the HDD and finding that the SSD was not underneath, I was stumped. Then I looked closely at the video card and found there was a Samsung 256GB M.2 SSD mounted the riser board. I didn't know how to turn it off, so I just removed it by removing the screw and lifting it off of the riser board. 

So, new question: how do I wipe the M.2 SSD so I can use it as additional storage for PhotoShop and LightRoom? 

I use Macrium Reflect for Imaging/Cloning.

To completely erase the old SSD (and remove even the hidden and OEM partitions) ... I suggest a "DiskPart clean" of the drive (but be careful with that command).

I don't use MiniTool by PartitionWizard, but the Manual has those tools

I'd probably Delete Partitions, then format them afterwards, or try Wipe Disk section (photo) Clean Disk / Wipe / Delete All Partitions etc; having never used that software I'd play around in there since many sections of their Manual otherwise accomplish the same thing (delete all partitions & erase / format drive);

I generally use Windows Disk Management &/or Command Prompt to do same; however, if an OS is installed, generally Disk Mngmnt will not delete all partitions, where CmndPrompt (Clean Disk) will --> play w/ MiniTools, do some reading & see what happens; step-by-step instructions will have to come from a member familiar w/ that software

You will want to back up your new SSD of course, as in backup your Windows install on something in case of need for recovery later

edit: I didn't see Tesla answer b4 I started to type & post here --> DiskPart is part of CmndPrompt I linked to

edit: if your SSD is on a riser card, it is an X51 R3, not an A51. The M.2 SSD (size of a stick of bubblegum) is generally considered (a fraction) faster than a basic 2.5" SSD, where next time u may look at 512 M.2 SSD as your boot drive (Samsung 970 EVO / Pro etc)
