Now that the Wii U has launched in the US, Nintendo have seen fit to release an FAQ addressing the storage concerns with the system and the use of external HDDs.
Let’s face it, the 8GB and 32GB Wii U solutions are not going to be able to hold much. My 250GB Xbox360 has had to have stuff deleted for more space and the 320GB PS3 is nearly full. So what is a gamer to do? Buy a new Wii U each time the previous one is filled up? Of course not. The Wii U supports external storage for the avid downloader, but it is not quite as straight forward as one would have hoped. No flash drives, no SD cards for downloaded games, no solid state drives, and somewhat iffy support for bus-powered external HDDs. Your solution? An external HDD with its own power supply – as long as it is under 2TB at the moment (support for 2TB+ drives is coming, but the Wii U will only recognise the first 2TB).
Anyway, check out the official FAQ right here and prepare your storage solutions.
