Sorry about that. Yes USB-2 is the limiting factor. I don't think it is quite as bad as you stated. They made 2 statements one about the tech being 13 years old. I agreed that the tech was 13 years old. Admitting that I felt I was implying the limits of the lightening port were dated and had technical limits.

I guess if the original poster hadn't made the gratuitous comment I would have been more focused on answering their valid comments. This is a good lesson for me to not be trolled and others to not make gratuitous comments. Finally apologizing if someone feels one has been rude.
