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
SATA & U.2 Connector Types
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.

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.

Thunderbolt Icon

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.

S.M.A.R.T. Icon

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.
