Sonnet's 4-port USB-C card gets the power required to operate connected drives from the slot it's installed in. Ordinary USB-C cards need a separate power plug connection.

Unlike ordinary USB-C adapter cards, the Allegro USB-C 4-Port PCIe was designed with a focus on intelligent power delivery and management for powering attached drives through its ports. The Allegro card provides 7.5W of power through each of its ports, supporting USB bus-powered hard drives, and SSDs without the need to connect an additional AC power adapter. With four drives connected, the four ports support simultaneous 300 MB/s transfers! Unlike other 4-port USB cards (simple hubs that split a single USB controller's bandwidth between all four ports), Sonnet's Allegro USB-C 4-Port PCIe computer card supports data transfers from a single USB 3.1 Gen 2 SSD RAID device at up to 800 MB/s- compared to using a USB 3.1 Gen 1 or USB 3.0 adapter card, transfers complete in half the time! Exploiting its dual controllers design, it's possible to simultaneously transfer data to two connected drives at up to 660 MB/s each. With two controllers onboard, the Allegro card speeds data transfers between connected drives, and enables your computer to load and off-load data more quickly. Break through the bottleneck-install Sonnet's Allegro USB-C 4-Port PCIe card in your Mac Pro tower, Windows PC, or Linux computer with PCIe slots or Thunderbolt to PCIe card expansion system to support your fast USB drives at maximum performance.įeaturing two 10Gbps USB 3.1 Gen 2 controllers and four USB-C ports, the Allegro USB-C 4-Port PCIe card supports data transfers at up to twice as fast as USB 3.0 and USB 3.1 Gen 1 ports are capable. But, most desktop computers (even new models) include generations-old USB interfaces that will throttle that performance and may not offer adequate power to allow bus-powered drives to operate. 2x the Performance of USB 3.0 and USB 3.1 Gen 1 ConnectionsĮquipped with SSDs, the fastest 3.1 Gen 2 USB drives you can buy today are capable of 800 MB/s data transfers-many are bus-powered, too.
