Do you need more storage capacity for your computer? Is super high-speed throughput plus maximum IOPS (Input/Output Operations Per Second) performance critical to your work? U.2 NVMe PCIe SSDs deliver both. Sonnet’s Fusion™ Dual U.2 SSD PCIe Card enables you to upgrade your system in a flash, mounting two enterprise class U.2 SSDs with up to 32TB or greater capacity(1) in a single full-length x16 PCIe card slot, with no separate power or data cables, drive adapters, or mounting trays required.



U.2 SSDs look like 2.5-inch SATA drives — they even share the same general dimensions and mounting screw hole placement, but their connectors are different, and so is their performance. Unlike SATA drives, U.2 NVMe SSDs interface with your computer’s PCIe bus, enabling them to perform seven times as fast.


How fast? Current PCIe 3.0 U.2 SSDs deliver sustained performance of up to 3500 MB/s read and 3500 MB/s write, or about 7x the performance of the fastest SATA SSDs.


Many U.2 SSDs are now available in capacities up to 16TB — perfect for storing large video projects—with higher capacity models on the horizon. Sonnet’s Fusion Dual U.2 SSD PCIe Card will support bigger SSDs as they become available.


Install the Fusion Dual U.2 SSD PCIe Card with your SSDs into your system and configure the SSDs as a RAID 0 set for even greater storage performance.


The Fusion Dual U.2 SSD PCIe Card is a full-height, full-length PCIe 3.0 card with an x16 (x8 electrical) interface, designed to support full performance from two U.2 NVMe PCIe SSDs. The Sonnet card features:

  • CIe Bridge Devotes four lanes of PCIe 3.0 bandwidth to each SSD installed
  • Self-contained Doesn’t require a specific motherboard to operate or specific SSDs to support RAID features — No PCIe bifurcation is required
  • Universal Compatibility Mac®, Windows, and Linux compatible
  • Mounting Support for Two U.2 SSDs Connect and mount directly to the card, no power or data cables, adapters, or mounting trays required


Unlike M.2 SSDs, which require heatsinks to be attached to enable stable performance, U.2 SSDs are designed with their cases acting as heatsinks—that means installation is much easier. As a result, the Fusion Dual U.2 SSD PCIe Card doesn’t need a fan to keep the SSDs cool enough to enable them to maintain their high performance at all times.


Got a Thunderbolt connection, but no PCIe card slot? Sonnet’s Fusion Dual U.2 SSD PCIe Card is ideal for use in one of our Thunderbolt 3 expansion systems that accept full-length PCIe cards. The combo enables you to add two U.2 NVMe SSDs to any Mac computer with Thunderbolt 2 or Thunderbolt 3 ports, or Windows or Linux computer with Thunderbolt 3 ports.


NVMe compliance ensures that integrating a Fusion Dual U.2 SSD PCIe Card into your system is easy—the necessary drivers are installed automatically. The Fusion card uses your computer’s built-in drive formatting utilities to format the SSDs. SSD health monitoring is supported through S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) data reporting, too.

Technical Notes

  1. As of 09/2020, the current maximum capacity of most U.2 SSDs is 16TB. This product will support higher-capacity SSDs as they become available.
  2. This product’s performance will vary based on the type and number of SSDs used, the CPU speed, and the PCIe architecture.
  3. Performance in a Thunderbolt 3 PCIe expansion chassis limited by maximum Thunderbolt 3 PCIe bandwidth of 2750 MB/s. PCIe bandwidth of Thunderbolt 2 is about half of Thunderbolt 3.

        Customs, duties & taxes

        There are no customs duties or taxes on orders shipping within the EU. Orders shipped outside of the EU may be subject to import taxes, customs duties and fees collected by the destination country. The recipient of an international shipment may be subject to such import taxes, customs duties and fees, which are collected once a shipment reaches the recipient's country. Additional charges for customs clearance must be paid for by the recipient; we have no control over these charges and cannot predict what they may be. Customs policies vary widely from country to country; and when customs clearance procedures are required, it can cause delays beyond our original delivery estimates. We advise that you contact your local customs office for more information.
