I already have 3 of these 2TB drives. Have had them for at least 5 years and zero problems ever. Perfect for storing unimportant data that your Mac doesn't have space for. https://www.amazon.ca/gp/product/B00FRHTTJE/ref=ox_sc_act_title_1?smid=A26WHA4EX5Y0CA&th=1 I'm thinking of getting a couple of 4TB or 5TB versions. The reviews are very mixed but the reviews are for all of them not for specific versions. Over the years I've heard not to buy large capacity versions like the 4TB/5TB versions. What do you think?
