BEWARE, seller is completely uncooperative, received 2 Samsung 1 TB SSD, they are defective. Disconnect from my computer while trying to load software, cloning software does not work, Samsung software for this procedure to get any use of SSD does not work. Seller refuses to provide a return shipping label, tells eBay he is cooperating when he is NOT. Does not understand the difference between returning a working item, vs a defective one.
