Samsung 512GB NVMe M.2 2242 for laptops. I'm selling all 7 together in a lot. See CrystalDiskInfo closely for each drive detail. They are not all the same part number.
One of them is labeled 256GB which has its own two photos. CrystalDiskInfo shows the model as 256GB but also 512GB in the same line. Disk Management and properties show 512GB and a different drive model. The serial number on CrystalDiskInfo and on the label matches. This one is a strange one but it doesn't appear to affect the functionality of the drive. As far as I'm concered, it's a 512GB usable drive.
All NVMe is excellent physical condition tested one by one on a secondary slot of an ATX motherboard. They were originally pulled from Lenovo ThinkPad E15 and E16 laptops. All drives are wiped with Diskpart and ran with the "clean" command.
