WD Elements Portable 1TB USB 3.0 - 500mA

How much power does the mentioned drive need from USB port? I have an blu-ray player that can only support devices that do not exceed 500mA. Will the mentioned drive work?

Well AFAIK the 2.0 devices draw 500ma

the 3.0 can get up to 1000ma so not sure this will work

you will be better off using a 2.0 drive or a drive that comes with a power adapter
