Can someone please recommend the least expensive way to go for my situation? I have a sata II 90GB ssd and I have a WD5000AACS it says sata 3.0 green drive. Whats my best option to use one of these with the wiiu? Would the ssd work self powered it doesnt draw much current but I know they say use ac powered so several factors to consider like I really dont need this 500GB drive for just games will the 90GB be enough and then the enclosure...please recommend a solution.
