Currently I have a SSD storing my OS alone and a 1 TB hard drive storing my program files and game files on the same drive. I need a new drive because this drive is now full, and I feel getting a drive separate for game files would be worthwhile. However I am not sure whether to buy a 2 TB hard drive or a 3 TB hard drive. At the moment I have around 90 pc games (more or less) which together combine to just over 700 GB worth of data. I am not sure whether buying a 2 TB hard drive will, in time, be too small for my growing steam and origin libraries, since game files are getting much bigger as quality increases. I do play modern games too, so the file sizes are usually rather large. As well as this I am unsure whether to get a WD black drive for the extra performance. They are considerably more pricey and I am unsure of the performance gap between black drives and a standard green or blue drive (I don't know how much better black drives really are). I would prefer to keep my games together on the same drive that is why I am wary of getting a 2 TB hard drive and it possibly becoming too small, and having to buy another drive. This is because I am also going to get a few other drives, such as a 3 TB hard drive to store high quality DSLR images for photography. Also would a green drive suit this need well as an energy saving drive? Also where would be the best/cheapest place to purchase these drives new (available in the UK). Many thanks for any feedback, kind regards, Tom
