I've only had it a short while but the speeds are impressive. With that said, it's going to be up to the endurance test that will show whether this drive will be a good long term investment. Also, it should be called the Barracuda Pro 4TB as seen here: https://www.amazon.com/gp/product/B01MSW4MNS/ ^{[Jul '17 IanPPK]}
