I am hoping to understand a bit more and also hopefully have a compilation of choices for those looking for storage an a bit overwhelmed with the speed and conecctions confusions. Hope I am not the only one. I wanted to buy an external hard drive and was looking for that new fast 10 gb speed I had seen somewhere. I did think that usb-c devices meant faster already but soon realizing that conector not always relate so clearly. ok..to simplify my question. what's the faster external hd with usb-c connectors? so, i see 3.1 gen 1...and 3.1 gen 2...arrrrr... any suggestions for a good fast/affordable external HD for my new macbook pro 2016? thanks a million.
