    Looking to add more usb ports to the back of my mac pro using a pci-e card

    Do I have to worry about drivers and compatibility? Will it be stable?

    Thinking of getting one of these


    Using a 2008 mac pro

    cheers!

    you dont have to worry about drivers for USB PCI express cards as its plug n play. the card will be stable if it isnt faulty.

    however the Mac Pro only has PCI express x16 (full length) slots and that card is PCI express x1 and i cant actually find a full length PCI express USB card!?

    Why would you need a 16 lane USB card? The Belkin should be just fine.

    That's the beauty of PCI-Express. You can fit an PCI-Express x1 card into a PCI-Express x16 slot.

    OH! sorry! i thought you could only fit that card in a PCI express x1 slot because they are added on PC motherboards these days as well as PCI express x16 slots. you learn something new everyday!

    oh man those Mac Pros are looking so tempting everytime… 4 PCI express, double wide PCI express for a big graphics card, on board WIFI and Bluetooth drool

    Not the best article on PCI-Express lanes but the show taping off to get the point across. The Mac Pro has full length slots even if they're not all 16 lanes. ;)

    Kinda like how you could fit a 32-bit 33 MHz PCI card into a 64-bit 66 MHz PCI slot... or 133 MHz 64-bit PCI-X slot? ;)
