My pc model is

Lenovo Y570 / intel i7/ 8gb RAM / 750 gb hdd [western digital scorpio blue 7500bpvt / sata ii (3 Gb/s)]

I want to have a new hdd (not ssd) but I can't find a western digital 500 gb sata ii model.

The ones that I could fine are all sata iii (like WD5000LPCX) Would it be a problem?

And aren't they selling sata ii models, because I'm having trouble to find one.

Also, what should be my priority when it comes to hdd? Rpm or cache or sata?
