Mick has a good point. I have two or three of the cheaper USB external enclosures and only one of them was somewhat fast, it is USB 2.0 after all. The other two logged a lot of errors in messages file about resetting something. It was resetting so often that moving data to or from the drive was very slow. I pitched the two bad ones, saved the one that works but bought a known good one, it has a fan and a display with the temps and fan RPMs etc on it. It is a eSATA or USB enclosure. I use the eSATA port and it is as fast as my internal drives. If interested, I can find a link for one so you can see what it looks like. I can also find the one that doesn't work just in case you have it. The good one is black and the iffy ones are a silver color. Point is, not all external enclosures work well. USB ports in my experience really complicate matters. I like USB for my camera and my little card reader, that I use to get deer pics off my trail camera. Other than that, I try to avoid USB. Oh, printers tend to work too. Dale :-) :-)
