Hello I would like to upgrade my Mac pro to USB 3.0 and I wanted to get a clear picture on things. I saw this on the web: http://www.amazon.com/HighPoint-Roc...untain/dp/B00BFNR0OA/ref=cm_cr_pr_product_top It says it's compatible with mac pros and all looks well. However, I had a "technical" person tell me that if my computer doesn't have USB 3.0 connections on the inside of the machine then I won't get USB 3.0 speeds. So I was thinking (if this was true) there is no point of upgrading. Anyway, any input on this matter would help. Thanks.
