If you need proper USB 3 speed then simply resign yourself to the fact that you'll have to upgrade your Mobo - moden laptops though have decent USB 3 ports. You can probably connect 2 or even 3 USB 3 HDD's to a POWERED USB3 hub without too much reduction of speed or I/O transfer.īaring in mind that a typical USB 3 external drive (passport type of self powered variety) probably will only give up to 110 - 200- Mib/s on USB 3 port (Mib/s - not MB/s) anyway you won't have any problem connecting another 2 or even 3 USB 3 devices to a decent USB 3 hub, It needs to be powered of course for maximum performance.Īs for USB 3 expansion port cards on older MOBOS that never had native USB 3 ports - IMO they are usually a waste of time since they connect to the BUS which doesn't have USB 3 speed in the first place. So even 2 or 3 devices will work just fine on a USB 3 Hub provided there is enough power supplied to the devices. Most USB3 HDD's (that's what most people use a USB 3 Hub for anyway) don't have anything like enough speed to limit the USB 3 hub speed - as well as most I/O will be done reasonably well by Windows anyway.

The 5V aux power is provided to the StarTech card by connecting the internal USB port (J33 near the power supplies on the D元80 motherboard) to the 15-pin aux power. It has a SATA 15 pin power connector for the aux power. There's NOTHING WRONG in using a USB3 hub - provided it has enough power to drive the devices connected to it. The solution I came up with is to use a StarTech PEXUSB312A card which provides 2 USB 3.1 ports and requires a PCIe X slot. Actually it's a bit more complex than that.

Will usb 3 card work on old mobo
