I'm currently using Nintendont with a 32Gb SDHC Card, but of course it's quite limited. So I was thinking about switching to an external HDD, or a 64/128Gb USB flash drive (way cheaper than an HDD and just the size I'd need, since I don't plan on getting every GC game in existence).
Apart from the size increase, is there any other advantage to using Nintendont with USB? Like better compatibility, speed or such?
Is there anything specific to install (either on Wii or Wii U vWii) in order to make that work, or is it as simple as USB?
And last question, what would you recommend for a 64Gb or 128Gb size between SDHC card, USB flash drive or external HDD?
I'm aware that SDHC cards have a limited lifetime regarding write cycles and are quite fragile, so I'd like something which can last as long as possible (I'll only use it for GC/Triforce games on Nintendont, and I sometimes switch between Wii and Wii U vWii because reasons).
Many thanks
