The new Sonnet McFiver brings internal SSD storage, 10 Gigabit Ethernet, 10Gbps USB-C, and two SSD slots for high-speed storage in a single PCIe card for the Mac Pro or any Mac with an PCI-E enclosure.

Sonnet has long provided systems with PCIe slots, and computer adapter cards, but now the new McFiver offers five interfaces in a single full-height PCIe card that requires no external power.

"For most creators, the ability to move files quickly — whether to or from onboard storage, across a network, or to or from external drives — can be critical to their workflows," says the company in a statement. "While individual adapter cards may offer the capability to speed up one part of the workflow, installing three adapter cards to get all the interfaces a user needs may not be feasible, even in computers with multiple expansion card slots."

The five interfaces in the McFiver are:

  • 10 gigabit Ethernet (10GbE)
  • Two 10 gigabit per second USB-C ports
  • Two slots for single- or double-sided M.2 NVMe 2280 PCIe SSDs

Note that the SSDs are sold separately, and Sonnet says up to 16TB total SSD storage can be installed on the card. It uses an x8 PCIe 3.0 bridge chip, so does not require specific SSDs, nor PCIe bifurcation to support RAID features.

When placed directly into a system such as a Mac Pro, using its PCIe 3.0 or 4.0 card slot, Sonnet claims that "a single NVMe PCIe SSD installed on the card can deliver data transfers up to 3,400 MB/s."

For every other Mac, and any computer that has no PCIe card slots, the McFiver can be installed in a separate Sonnet system, or a leftover eGPU enclosure. The company's Echo Thunderbolt to PCIe card expansion system brings "the McFiver card's interfaces through a single cable" to the Mac Studio, MacBook Pro, iMac, and more. Total bandwidth available to the card will be limited by Thunderbolt speeds.

The McFiver will be available from Sonnet from the second week of June. It will retail for $399.99.
