The Most Economical Way to Add Ultra-fast, Extra-large Capacity SSD Storage

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 30.72TB or greater capacity in a single full-length x16 PCIe card slot, with no separate power or data cables, drive adapters, or mounting trays required.

Enterprise Class Performance & Capacities

Familiar Size and Shape, Different Connector and Interface

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.

Striking Performance

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.

High Capacities

Many U.2 SSDs are available in capacities up to 30.72TB — 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.

Fantastic RAID 0 Performance

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.

Performance based on ATTO Disk Benchmark (available on the Apple® App Store) test results with two Micron 9300 7.68TB NMVe drives with 64MB transfer size and macOS® 10.15.6 using SoftRAID software. See our Fusion Dual U.2 SSD PCIe Card Performance PDF for additional benchmarks and details.

Sonnet Advantages – Full Performance Design

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:

PCIe 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

Key Features

Add up to 62TB Ultra-Fast Storage

Mounts two 15.36TB U.2 NVMe SSDs (sold separately) in an x16 PCI slot.

High-Performance PCIe Interface

PCI Express 3.0 x8 host bus interface is bridged to the SSDs, devoting four lanes of PCIe 3.0 bandwidth to each installed SSD.

Fantastic Performance

Achieve sustained RAID 0 transfer speeds up to 6,250 MB/s.

RAID Support

Supports macOS, Windows, and Linux RAID 0 and 1 configurations.

macOS Boot Support

Supports booting from a single (non-RAIDed) attached SSD.

Optimized for Thunderbolt

Use in Sonnet Thunderbolt expansion systems to connect two enterprise SSDs through one cable with performance up to 2800 MB/s.

NVMe Compliant

No drivers required.

S.M.A.R.T. Operation

Supports S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) data reporting.

Free Lifetime Tech Support

Sonnet was established in Irvine, California in 1986. Since then, we’ve pioneered and brought to market many innovative and award-winning products that enhance the performance and connectivity of Mac, Windows, and other industry-standard computers. Many of our employees have been with the company for more than 20 years. We have a wealth of knowledge about our current and past products. Should you ever need technical support on one of our products, contact us; we’ll be around to help you.

Mac Pro 5,1 User?

Mac Pro 5,1 users can install macOS on one SSD to create an incredibly fast boot drive and use the other installed SSD as a super-fast media storage or scratch drive. The Fusion Dual U.2 SSD PCIe Card makes it possible.

Silent and Cool Running

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.

Connect Two Enterprise SSDs Through One Cable to Your Computer without Slots

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 expansion systems that accept full-length PCIe cards. The combo enables you to add two U.2 NVMe SSDs to any Mac (M1, M2, M1 Pro, M1 Max, M1 Ultra, Intel), Windows, and Linux computer with Thunderbolt ports.

Simple and S.M.A.R.T

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.
