Hi I know you said I can go higher than 8TB @ the moment I have a 4TB in my Egreat A8 I was thinking of getting a external 4Tb hard drive Something like this https://www.amazon.co.uk/dp/B017KE8OG0/?coliid=I1W6D6BLKHA6BZ&colid=1R0IYA45R6XG9&psc=1&ref_=lv_ov_lig_dp_it would this be OK for my A8 USB socket as it is cheaper than getting a internal one Thanks P. S. At the moment i am filling my 4TB internal Drive with films but to get it to work OK I had to use a main unit via a socket then on to a usb socket to my PC would I have to use the same sort of thing with the Amozon one?
