Can anyone recommend a 4TB NAS drive for under £200 ? I've been looking at these two model, 1. Seagate 2. WD These both includes a USB port but thats only for expanding the size. I would like a USB port so that i have the option to connect to a computer so i can transfer files onto it if i have to take the NAS somewhere else. I've also seen things called 'Business Storage NAS drive' which are a bit more bulky in size. Not sure what the difference is though. My drive will only be used to store Movies/MP3's on so that i can access wirelessly via Mac Mini, Ipad, PS3, Android Phone remotely.
