Currently I am having USB 2.0 port Laptop. I am in the plan to buy USB 3.0 Pendrive/External Hard Disk. Whether USB 3.0 pendrive/ext HDD will support USB 2.0 Laptop's port? Or it will have problem to use?

Thanks in advance.

USB is backwards compatible so you can use USB 3.0 device in an USB 2.0 port, but the device will only run at USB 2.0 speed.

  • Assuming it doesn't draw more than 500mA. That's a safe assumption for a flash drive, but maybe not for a USB 3.0 external hard drive. – Compro01 Jan 16 '14 at 21:05
