USB Review

Seems to work prefect. Be sure to add SATA power connector.

Good, but With a Catch

A great upgrade that may get you USB 3.0 speeds on older equipment. However, by the manual's own admission, you get one USB 3.0 port's worth of bandwidth split between the two ports. That may be because of the limits of the PCIe x1 interface So if you have one 3.0 device plugged in, it should work at full speed. But it you have two, both devices should be limited to half the bandwidth. It's still plenty of speed, but not quite the full upgrade that enthusiasts may be looking for. I say "should" because I wasn't able to get it working on the desired older computer. It may still work on a wide variety of computers. Upgrading older computers with newer tech has always been a patchy thing, so I can't blame StarTech for that. I will say that Best Buy made the in-store return process easy, so I'm not out anything other than the few days it took to come in. I'll definitely be sure to try something else!

Works well but you must add Sata Power Cable

This pci-e card did add USB 3 to my computer but you must connect a sata power cable for it to work properly. See item Telemax Ide-Sata 6" Power Adapter (TXIDESATA1) for an example. This card works with the standard Windows 10 64 bit driver rather than the manufacturers driver. It improved speed on one external hard drive from 30 MB per sec to 89 MB per sec write speed.
