[Q] What's the USB 3.0 for?

I believe sammy made internal sd cappable of transfering real quick, I tested it with my 32gb dunno wat was it called, but its supposed to be fast, like real fast...so 3.0 is from cellphone to computer, If yours support it, it will be the same as int storage to ext microsd(if it supports fast transfers)

I don`t think the USB 3.0 is useful at all the Class 10 SD Cards has a write speed of 40 MB/s USB 2.0 is 60 MB/s so yes the SD card couldn`t even match the USB 2.0 Spec and internal storage is only 16 GB so even if it`s capable of reaching USB 3.0 speeds which I highly doubt as the USB 3.0 speeds are really close to the SATA 3.0 Specs and currently there is no hard disk on the world matching the SATA 3.0 Specs so I doubt that the internal storage is capable of reaching USB 3.0 so yes the USB 3.0 is not useful probably the only reason we have it is because it charge the phone faster then a USB 2.0 cable because of the additional pins.

I think they went with usb 3.0 with the sole purpose of increasing charging rate, the batteries are starting to increase in size but the rate they charge hasn't really changed much so they went with usb 3.0 to increase the rate. Quickcharge 2.0 is coming soon though so that should help to

usb chargers are NOT usb 3, they don't have the extra back row of pins needed, they only use the standard 4 pin usb which is usb 2. if you use a charging program like galaxy charging current you get no improvement with usb2 over usb3. most s5's were only shipped with usb2 cables anyway. quick charge 2.0 is based on standard usb2.
