So im a little confused about external drives with usb 3 and TB . Does it even matter if its usb 2 or TB if the external drive its self isnt fast or am i not understanding correctly. So how can you tell what external drives are fast and witch are slow i know ssd will be faster but those are preety pricy so how can you tell if a regulare exteral drive is going to be fast or not also from your use what exteral drives are good
