I use this card to my computer yet fully sufficient (Core2Quad / Intel P45 chipset) to expand USB3 interfaces.
The card is solid and high-quality workmanship at first glance. It comes with screws and driver CD where you feel like at any hardware rather load the latest driver from the manufacturer's website should to avoid unnecessary problems.
I have tested this map together with the Inateck USB3 disk enclosure FEU3NS-1E and a conventional WDC WD2500BEKT-75A25T0 2.5-inch hard drive.
Crysal DiskMark this indicates sequential read rates of 102.3 and write rates of 99.21 MB / s. So almost the maximum that the conventional hard drive creates. With SSD are still significantly higher data rates to achieve.
I can not confirm, but I tested the card only under Windows 7 show other reviews the problems. If problems arise on Windows 8, I recommend the latest driver from the Inatek website to load and contact support.
5 stars from me for a solid product with super price / performance ratio!
