I have my desktop which has windows 8.1 and I use it as my primary work station. I want to use Ubuntu 14.04 and I dont like to dual boot on my PC. I want to install ubuntu on external SSD and use it as my primary OS and I want to keep my windows 8.1 on my primary HDD in computer for gaming and other stuff. But My concern is I know ssd is faster but I think if i use it through USB port I might not be able to get the best out of my SSD. So what could be the other best option for that or its ok to keep using the SSD from usb3 port.
I know that we can use sata ports as external port. I can use one of those connectors to use directly the sata port but again, when I will boot it won't give me an option to boot from my external SATA SSD drive rather it will always boot from my primary HDD unless I enable dual boot which I really dont want.
