Hi I have upgraded my older 4520s notebook to max ram, and SSD drive with Win 10 pro. I am disappointed no USB 3.0 slot. I understand I can upgrade thru PC express slot with adapter card. Question is what mfg is a good choice and will the bus supply enough power to run external drives without using external power supply, that would take the potability away from it.
Thanks for any information, I am trying to avoid the power supply to run the 3.0 card
