Sonnet McFiver PCIe Card
Multifunction Adapter Card with Dual M.2 NVMe SSD Slots, 10Gb Ethernet, and Two 10Gbps USB-C Ports
Multiple Functions. High Performer at Each One – Only multifunction PCIe adapter card with M.2 NVMe storage, 10Gb Ethernet, and 10Gbps USB-C connectivity.
Are you looking to add SSD storage, ultra-high-speed Ethernet connectivity, or high-performance USB-C® ports to your setup? Or all three? Even in computers with multiple expansion card slots, installing three adapter cards to get the interfaces you need may not be feasible. Sonnet’s engineers designed a truly unique solution — the McFiver™ PCIe® Card. Mac, Windows, and Linux compatible, this professional, multifunction adapter includes five interfaces — this is the only adapter card to feature dual M.2 NVMe SSD slots, one RJ45 10Gb Ethernet port, and two 10Gbps USB-C ports, fitting them all on a standard full-height PCIe card.
One PCIe x8 Slot is all You Need
Install the McFiver PCIe Card into an available x8 PCIe 3.0 or 4.0 slot to obtain maximum performance in your computer. No PCIe card slots in your computer, but Thunderbolt ports outside? The McFiver provides great performance, a lot of connectivity, and is ideal for use in an Echo™ Thunderbolt™ to PCIe card expansion system with an available full-height x8 card slot. The combo enables you to take advantage of all that the McFiver has to offer with any compatible Mac (M1/M2, M1/M2 Pro, M1/M2 Max, M1 Ultra, Intel®), Windows, or Linux computer with Thunderbolt ports.
Dual M.2 NVMe SSD Slots – Add Up to 16TB of SSD Storage
McFiver PCIe Card provides mass SSD storage capability on a PCIe card. Dual M.2 NVMe PCIe SSD slots support up to 16TB internal high performance storage expansion (SSDs sold separately), enabling you to save and access your data fast, and effortlessly store large files and media libraries.
If super high-speed data transfers are critical to your work, you need an NVMe SSD-based upgrade. Installed on the McFiver PCIe Card, a single NVMe PCIe SSD can deliver tremendous performance — up to 3500 MB/s read and write sustained data transfers — but the McFiver enables you to mount two of them. Formatted as a RAID 0 set, two SSDs can achieve sustained transfers up to 6600 MB/s read and write. No matter how you use it, you’ll love the speed.*
10Gb Ethernet Port – Blazing-Fast 10GBASE-T Connectivity
The increasing demand for wired network bandwidth has pushed 10Gb Ethernet (10GbE) into the mainstream. It’s not just for use in software development, postproduction, and shared storage workflows where speed is critical — there’s increasing need for it in workflows of all kinds and businesses of all sizes. Very affordable 10GbE switches have reduced the cost of upgrading, but many computers don’t natively support 10GbE — the McFiver PCIe Card can get you connected. The cFiver is equipped with one RJ45 port that enables you to connect your computer to 10GbE infrastructure via Cat 6A cabling at up to 100 meters.
Two 10Gbps USB 3.2 Type-C Ports
High Performance USB 3.2 Gen 2 Controller – 10Gbps USB 3.2 controller can concurrently deliver full 10Gbps bandwidth through both ports.
Broad USB Device Support
The McFiver PCIe Card offers hot-pluggable and hot-swappable device connection support with automatic device configuration, and works with all USB-IF compliant USB peripherals.
*Internal SSD performance will vary based on the type and number of SSDs used, plus the host computer's CPU speed
