PROFESSIONAL MULTIFUNCTION PCIe CARD

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.

Two M.2 NVMe Slots

Add up to 16TB of storage with your own high performance M.2 NVMe SSDs

One 10GBASE-T 10GbE Port

RJ45 port connects your computer to 10GbE infrastructure via inexpensive copper cabling

Two 10Gbps USB-C Ports

Adds two USB-C ports with full 10Gbps bandwidth per port

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 or all that the McFiver has to offer with any compatible Mac (M1, M1 Pro, M1 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.

Super High-Speed Data Transfers

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 3400 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.

Silent SSD Cooling

No Thermal Throttling. No Slowdowns. SSDs heat up significantly when performing very large file transfers and will protect themselves from overheating by “thermal throttling” — a feature that drastically cuts SSDs’ performance while allowing them to cool. The McFiver PCIe Card’s silent SSD cooling solution works to eliminate the need for thermal throttling and enables your SSDs to always maintain their highest performance.

SSD SMART

Installing your M.2 SSDs on the McFiver PCIe Card is a simple task, and the card uses your computer’s operating system’s built-in drive utilities to format them. SSD health monitoring is supported through S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) data reporting. Are you a Mac user? You can install macOS® on one SSD to create a very fast boot volume, and then use the other installed SSD for file storage; as a super-fast plug-in, media storage, or scratch disk; or for Time Machine® backups.

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 McFiver 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.

Multi-Gigabit Ethernet Support for Faster Transfers Across Existing Cabling

If your facility already has Cat 5e wiring installed, you can still get an amazing performance gain — from 250 to 500 percent over Gigabit Ethernet speed — without rewiring! The McFiver PCIe Card supports the NBASE-T™ industry-standard (multi-Gigabit Ethernet) of 2.5Gb and 5Gb link speeds to enable greater than Gigabit Ethernet speed over Cat 5e (or better) cabling when used with a multi-Gigabit compatible switch or router. You can utilize the same adapter card across your organization for users supported by different Ethernet cabling infrastructures to obtain the best possible performance.

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.

10Gbps USB Performance Bliss

The fastest USB 3.2 Gen 2 drives available — equipped with NVMe SSDs — can transfer data at incredible speeds. Can your computer support their full performance? Upgrading your workflow with Sonnet’s McFiver PCIe Card ensures 10Gbps USB SSDs can operate at their peak performance.

High Speed Simultaneous Transfers

Many multi-port USB cards split their USB controller’s total bandwidth between all their ports, which limits performance when two or more devices are connected and operating. The McFiver PCIe Card features an advanced USB 3.2 Gen 2 controller that delivers full 10Gbps bandwidth per port and implements advanced data traffic management to eliminate bandwidth congestion. When installed in a computer’s PCIe 3.0 or 4.0 slot, the McFiver PCIe Card supports two simultaneous 10Gbps transfers, enabling it to transfer data from two drives to the computer (and from drive to drive) at maximum speeds of 1000 MB/s per drive.

Sonnet Port Power Advantages

Sonnet designed the McFiver PCIe Card with a focus on intelligent power delivery and management for attached SSDs powered through its ports — unlike ordinary USB adapter cards designed without attention to detail.
