I am planning to buy a lenovo y510p but what caught my eye in the spec sheet is the 5200rpm hdd. So I just though I could switch it t an ssd but it happens to be too expensive. So then I found SSHD which I guess is a combination of both and is faster than is 5200rpm. But I couldn't find any guides or videos which would tell me if it is even doable. By the way I do need 1 tb of storage so buying a ssd with a lower storage would not work for me.
