We have a computer that runs a $150k microscope. As we always have a data storage issue, I want to upgrade the computer with a USB 3.0 card and store data on external disks. Other than making sure I have a spare PCI slot (or PCIe?)(not trivial as their are a lot of cards in there - I cannot check it right now it's in use), what do I need to look for in terms of minimum requirements?
How much power will it draw? I only need a simple card - even a single port, but I cannot tax the power supply. I cannot upgrade anything else in there. It runs Win XP professional.
