I like the idea behind this product and would love to buy it, but there are two dealbreakers here - the HDD limit of 3/4TB, and no Mac formatted drive support.
I want to use it to stream movies on my iPad Air 3 from external HDDs that I could plug into this hub. But all my HDDs are Mac formatted and I’m not about to convert to windows or FAT - they’re full of movies and it would be too much work. And all of them are 8TB.
If they can solve these two issues I’ll buy.
Portable wireless devices like this are few and far between - I have these from RAVPower and another from Kingston and they have similar specs. The market for them is pretty limited so I doubt you'll ever see one fitting your needs.
