I purchased 10 of these drives in 2025 for a project that did not come to fruition. I have never used them, though sadly removed them from the box to pack inside a pelican case where they remained until now so I could take photos to sell. IMPORTANT:  I've included photographs that show the Samsung magician program analysis of 3 of the drives to show there is no read or write on any of the drives. I will happily provide additional Samsung magician analytics on the other drives if requested so show there is no read or write. PLEASE NOTE: using the Samsung magician program does engage the drive a small amount bc the program must access and read the drive. 500 dollars a drive or 5000 total. These drives on Amazon are over 1,000 USD right now. This is a killer deal.
