External HD USB ports
I need to buy an external hard drive for backups. I have only USB2 ports on my Windows 7 PC. When it dies, I will probably replace it with a PC having only USB3 ports.
Why do the ads for some drives show only USB3 and some both USB2 and USB3? I thought USB3 was downwards compatible with USB2?
Thanks for any help anyone can give me.
