Sonnet Allegro USB 3.1, Two-Port USB-C 10Gb PCIe Card (USB3C-2PM-E)

Add SuperSpeed+ USB Technology
Add Two Powerful 10Gbps USB-C (USB 3.1 Gen 2) Connections to Your Mac Pro Tower, Windows PC, Linux Computer or Thunderbolt to PCIe Card Expansion System

When it comes to supporting the fastest USB drives available, your computer's USB 3.0 ports are perfectly adequate.. for connecting peripherals that don't depend on the ultimate USB 3.1 speeds. However, common USB 3.0 ports can be underachievers-at 5Gbps, they can't support the maximum performance from many storage devices and may not provide enough power to enable them to operate. You need SuperSpeed+ USB. You need Sonnet's Allegro USB-C PCIe card.

The Allegro USB-C PCIe supports data transfers at up to twice as fast as USB 3.0 and can also deliver 15W of power per port to USB-C bus-powered devices (three times the 4.5W specified in the USB 3.0 spec). Don't settle for mediocre performance or insufficient power for the fastest SSDs-install an Allegro USB-C card to instantly add two Gen 2 USB 3.1 ports to your system and take full advantage of today's SSD performance.

Speed and Power
Sonnet's Allegro USB-C PCIe computer card supports data transfers up to 960 MB/s when connected to a USB-C Gen 2 SSD RAID device-transfers complete in half the time compared with using a USB 3.0 2.5-inch SSD! Sonnet specially engineered the Allegro USB-C card to provide 15W of power through each of its ports. The ports communicate with the host that 3A of VBUS current is available, enabling this Sonnet solution to support USB-C bus-powered SSDs and SSD RAID devices that need 15W during demanding write operations.

SuperSpeed+ USB Technology-Adds two 10Gbps USB-C (USB 3.1 Gen 2) ports to your Mac Pro with PCIe slots, Windows PC, Linux computer or Thunderbolt to PCIe card expansion system; transfers data up to 2x as fast as USB 3.0 connections
Super-Powered Ports-Supports USB-C bus-powered SSD, SSD RAID and hard drive devices with up to 15W (3.0A) power per port
Protected Ports-Independent power regulation isolates each port to prevent cross-coupled power glitches that may cause accidental disconnects
Resettable Fuses-Device overcurrent fuses are resettable-just shut down your machine to reset a fuse without permanent damage to card or computer
PCIe Data Link Auto-Negotiation-Card auto-negotiates one lane data link in a PCIe 3.0 slot and two lanes in a PCIe 2.0 slot, ensuring full 10Gbps performance in either generation PCIe slot
Broad USB Device Support & Compatibility-Supports storage, hubs and other USB-IF compliant USB devices
Supports Hot-Swappable Device Connection-Plug in and disconnect peripherals without shutting off your computer
Optimized for Thunderbolt-Provides maximum performance over Thunderbolt
Easy Installation-Quick and easy user installation into any available PCIe slot

Regulates Power to Each Port
Ordinary USB-C adapter cards deal with power delivered through the ports as an afterthought, requiring an additional power source for the card and providing little regulation. The Allegro USB-C PCIe is no ordinary adapter card. The Allegro card regulates its own power without requiring a back-of-the card power cable connection, thus enabling full compatibility in any computer or Thunderbolt expansion chassis that doesn't have these power connectors available.

Sonnet's Allegro USB-C is unique in regulating power to each port independently, giving each one protection from power glitches on the adjacent port. Without this protection (such as found on an ordinary card), connects and disconnects of one device may cause auto-disconnects of the other.

Resettable Fuses
The Allegro USB-C card features a resettable fuse on each port to protect the card and computer should there be a cable or peripheral failure. Should a fuse trip on the Sonnet card, you can reset it simply by shutting down the computer.
