PRODUCT INSTALLATION AND TESTING
Curiously, with a flash drive and external hard drive installed in the Type A ports and a couple more flash drives installed via an expansion device, Device Manager listed three devices with room for four more. At any rate, all the headers worked as expected and all devices were functional regardless of the configuration. I even set up the Corsair 4GB flash drive for ReadyBoost (By the way, ReadyBoost actually seems to actually be useful in Windows 7,) without any issues.
Using HD Tune, we'll see if there is a performance hit associated with the IU01. Here's a screenshot of the results with the flash drive connected to one of the front panel USB ports on my NZXT Panzerbox case. For what it's worth, I'm running an Intel E7200 (overclocked to 3.56 GHz) on a budget Foxconn mobo with 2GB of RAM and Windows 7 Professional.
With the drive connected to the IU01, we get identical transfer rate and access times. The only apparent difference is a slight CPU usage increase that is likely unrelated to the hub.
Next, I broke out my Western Digital 320GB Passport external hard drive and plugged it into the same front panel header. The above screenie shows the results.
When connected to the IU01, performance seemed to improve a miniscule amount, but again, I doubt it had anything to do with the NZXT hub. From this data, I think it's pretty clear that you can expect no measurable performance hit when using the NZXT IU01 module.
Just for grins, I connected an older external hard drive (that previously required two USB ports to power it from the front panel,) to the IU01 and it performed flawlessly with a single USB in the Type A port. I then connected the front ports of the case to the IU01 and experienced the same functionality there, as well.
