First off, I'm a novice when it comes to computer repair.. I have replaced RAM, replaced network cards, the occasional can of air blowing out the inside.. But this is my first SSD upgrade and install. I bought the refurb, because it was a little cheaper. The refurb comes with literally just the SSD. No sata cable at all. JUST the SSD. It also comes with NO instructions. Samsung has that part taken care of.. I went to Samsung's website and downloaded the the Samsung Magician and the Data Migration tool. I bought a used desktop for dirt cheap. It had a 128 SSD installed already with a fresh copy of Windows 10. I plugged in this refurb SSD into the secondary slot. I powered up the computer, saw that the Samsung Magician recognized the new drive. Opened the Data Migration tool, used the original 128 as the source, and the new 1TB as the destination. Less than 5 minutes later, I unplugged the 128 and placed the new 1TB in its slot. Copied everything over (including Windows 10) without a problem. If I hadn't have done it myself, I would have never believed it would be THAT simple. Highly recommended. Other reviews have said these drives are hit and miss. Mine was a hit. Again, no sata cable, no instructions. Literally just the SSD. But Samsung makes it simple with their tools. If I can do it, you can do it.
