I am purchasing an external hard drive which has USB 3.0 interface but I have a Dell Inspiron laptop which has USB 2.0 interface. Will The external HDD device work with my Dell laptop?
It is backwards compatible as everyone has mentioned, but I'd like to add that a USB 3.0 device on a USB 2.0 port would provide better speeds than a USB 2.0 device on it.
I've bought a Sandisk Extreme 3.0 and when I plug it into the 2.0 port, I get R/W speeds of 40-50/18-22 Mb/s
So definitely get a 3.0 device.
USB 3.0 devices are backwards compatable so yes.
Thank You Alan
YES YOU CAN
Thank You Anandu
USB 3.0 ports offer faster communication speeds and a slightly higher power output, but will work just fine with USB 1.1 and 2.0 devices.
Thank you Oron
USB devices are made to be backwards compatible. Much like USB 2.0 devices work in USB 1.0, USB 3.0 devices work in USB 2.0. I would recommend getting a USB 3.0 device over a 2.0 device because then any newer device or computer that is compatible with USB3.0 would be able to take advantage of the higher speed.
Thank you. That answers my question.
It will work just fine, but you will only get the USB 2.0 transfer speeds.
Thank you Bruce. That answers my question.
