Deliver Time

  • Once your order has been handed over to the carrier for delivery, you will receive a shipment notification email with an estimated delivery date. Please note that it is not possible to expedite your delivery and receive your package earlier than the scheduled delivery date. Therefore, we are unable to accept requests for expedited delivery. Our carriers are unable to provide an exact time of day for your delivery. If you ordered multiple items, you may receive separate shipments.
  • All estimates are based on business days. We only make deliveries in the specified areas of Hong Kong from Monday to Sunday except on the first two days of the Lunar New Year and when typhoon warning signal No. 8 or above or black rainstorm warning is in force.
  • All rescheduling of delivery, additional purchases, new sales memos and amendments must be made 3 days before the scheduled delivery date. Otherwise, a double delivery charge will be incurred.

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 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.

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.

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.

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.

macOS AVB Support

The McFiver PCIe Card supports Audio Video Bridging (IEEE 802.1Qav, AVB) under macOS. When used with a switch or router (plus infrastructure) with AVB support, the card is perfect for use in pro audio and video applications where synchronization of data streams is critical.

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.

Intelligent Power Delivery and Management

Independent, per-port power regulation – prevents power glitches that cause auto-disconnects of already-connected drives.

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.

  • Super-powered USB Ports - The McFiver card provide 7.5W of power through each of its USB ports, supporting USB bus-powered SSDs and hubs without the need to connect an additional AC power adapter to the device.
  • No Auxiliary Power Required - Ordinary USB cards need a separate power connection. Sonnet’s McFiver card draws all the power necessary to operate connected drives from the slot it’s installed in. This enables you to install the Sonnet card in any compatible computer or Thunderbolt expansion system regardless of it having extra power connectors available.
  • Independent, Per-Port Power Regulation - The McFiver card regulates power to each port independently, providing each one protection from power glitches on the adjacent port. Ordinary USB cards can provide poor power regulation, allowing a connected drive to be forced off (auto-disconnected) when an additional drive is connected or disconnected.
  • Resettable Fuses - Unlike ordinary USB cards, the McFiver card features a resettable fuse on each port that protects both the card and computer should a cable or peripheral fail. Resetting a tripped fuse is simple — just shut down and then restart your computer.

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.
