Sonnet Announces PCI Express® 3.0 Adapter Card With Direct Mounting Support for Two U.2 NVMe PCIe® SSDs

Ideal for the 2019 Mac Pro®

What’s New:
Sonnet Technologies today announced the Fusion™ Dual U.2 SSD PCIe® Card, the latest product in the company’s line of high-performance storage cards that enable the installation of SSDs into a computer’s or Thunderbolt expansion system’s PCIe card slot. The Fusion card supports two U.2 NVMe PCIe Gen 3 SSDs, which share the same form factor as 2.5-inch SATA drives but deliver up to seven times the performance of the fastest SATA SSDs available.

What It Does:
The Fusion Dual U.2 SSD PCIe Card enables users to install two enterprise-class U.2 SSDs (sold separately) into a full-length PCIe card slot, mounting and connecting the SSDs with no cables, adapters, or mounting trays required.

Why It’s Important:
For users who need to add storage to their computer setup and require ultra-high-speed data transfer speeds for a smooth workflow — such as video editors working with 6K and greater resolution footage — U.2 NVMe PCIe Gen 3 SSDs are ideal. Mainstream U.2 SSDs are currently available in capacities up to 16TB and support data transfers at up to 3,500 MB/s. With two SSDs installed on the Sonnet card and configured as a RAID 0 set, sustained data transfers up to 6,250 MB/s are possible.

The Fusion Dual U.2 SSD PCIe Card offers many users the most economical way to add ultra-fast, extra-large-capacity storage to their computers — particularly so for 2019 Mac Pro® users. The Fusion card plus two 3.84TB U.2 SSDs configured in a RAID 0 set deliver up to 184% the performance of the factory-installed 8TB storage option, but at a nearly 32% lower cost per terabyte. Purchasing larger U.2 SSDs, Mac Pro users can install up to four times as much (or greater) capacity as offered by Apple®.

How It’s Unique:
Compatible with macOS®, Windows®, and Linux®, the Fusion Dual U.2 SSD PCIe Card is the only product available that mounts two U.2 SSDs directly to the PCIe adapter card. Other U.2 SSD adapter cards require separate mounting space for the SSDs in the computer, plus additional data and power cables to connect the SSDs to the card and computer, respectively. The Sonnet card neatly connects and secures the SSDs in a single-width card space. For Windows and Linux computer users, the use of other cards may require reconfiguration of their systems’ BIOS settings, but the Sonnet card does not — no drivers or configuration are required for compatibility.

When You Can Get It:
The Fusion Dual U.2 SSD PCIe Card (part number FUS-U2-2X4-E3) is available now at the suggested retail price of $199.99.
