The 2-Port Allegro USB 3.0 PCI Express Controller Card from Sonnet is based on the new USB 3.0 standard that offers up to 10 times the performance of the decade-old USB 2.0 interface. A single hard drive with a USB 3.0 interface is capable of transferring data at up to 125 MB/s, while SSDs are capable of even faster transfers. You can install an Allegro USB 3.0 PCIe card into your computer to exploit the full performance potential of these fast drives.
The Sonnet's Allegro USB 3.0 PCIe features a PCIe 2.0 bus interface to take advantage of your computer's fast expansion card slots. Each of this card's ports supports bus-powered storage devices (devices that work without a separate power supply). The Allegro USB 3.0 card also supports hot-swappable storage connections.
