Are there ANY self-powered External Hard Drives larger 1 Terabyte or larger (preferably 2 Terabytes) that are energy efficient enough to be fully functional without a Y-Cable when hooked up to any of the Wii U's USB Ports?
It's possible, but due to how SD cards work they likely won't work well with an adapter in a 2.0 port, especially with larger games. I'd expect slowdowns and maybe even corruption, not to mention the price/storage/performance ratio wouldn't be great. It's probably best to invest in a USB hub and plug in everything but your HDD into it.Hmm. That kind of sucks, are external SSD's a thing? Or are Dual MicroSDXC to SDXC Adapters a thing?
