Hello members, I'm interested in buying this 512gb ssd from ebay and I'm a little bit confused if its the Samsung 970 pro ssd or 980 pro ssd , or is this a completely different ssd from the naming conventions of the likes of 970 and 980 pro, knowing this information will really help me because I know about the write speeds of the 970 and 980 pro ssds, I really want to know the speeds of this gen 4 nvme ssd before I go ahead with the purchase, I'm buying it for use in my dell precision 7720 workstation , thanks in advance for your answers
