I bought a cable to transfer files off my old computer internal HD to a new machine but it didn't work. I could have saved a few dollars ordering elsewhere, but I was in a pinch so I picked this up at my local store. It's my first SSD. I've used internal/external Seagate drives for years and tend to trust the brand, however, most externals have failed over time. I hope to get better life on this one. In terms of speed, Windows 10 seems slow to copy ANY files, even on the same drive, so I just drag, drop and go do something else. I like the compact size and I'm glad to have the stability of a SSD. I'm using it as an external/scratch drive for my applications on my new computer.
