Super High-speed Data Transfers

If you need to add internal storage to your computer and ultra-high-speed data transfers are critical to your work, you need NVMe SSD storage. While a single M.2 NVMe PCIe SSD offers tremendous performance — 10x more than that of a spinning drive — Sonnet’s M.2 2x4 Low-profile PCIe Card enables you to mount two of them into a single x8 card slot and combine their performance. No matter how you use it, this card can transform the way you work or play.

Low Profile – Fits Anywhere

Install in a computer or Thunderbolt expansion system x8 PCIe slot

RAID 0 Performance

Install the M.2 2x4 Low-profile PCIe Card with your SSDs into your computer with PCIe 3.0 or 4.0 card slots, and then configure them as a RAID 0 set to obtain data transfers up to 6600 MB/s.

Performance will vary based on the type and number of SSDs used, plus the host computer’s CPU speed

Easy Fit

Install in an x8 PCIe Card Slot

Sonnet’s M.2 2x4 Low-profile PCIe Card fits in almost any card space with an available x8 PCIe card slot, whether in a desktop tower, mini workstation, or server computer; or even in a Sonnet Thunderbolt expansion system. Included full-height and low-profile brackets enable a secure fit wherever you install it.

Full Performance Design

Sonnet Advantages

Sonnet’s M.2 2x4 Low-profile PCIe Card uses an 8-lane (x8) interface designed to support full performance from two SSDs. The M.2 2x4 card features:

16 Lane PCIe Bridge

With an 8 lane PCIe connection to the host, the high-performance PCIe 3.0 bridge chip devotes four lanes of PCIe bandwidth to each SSD to support maximum performance

Self-contained

The card’s SSD RAID configuration support doesn’t require a specific motherboard or SSDs to operate — no PCIe bifurcation required

Universal Compatibility

Compatible with Mac, Windows, and Linux computers with an x8 PCIe slot

Broad M.2 NVMe SSD Support

Works with a wide variety of M.2 2280 NVMe PCIe SSDs

Key Features

Add up to 16TB of Ultra-fast Storage

Mounts one or two M.2 NVMe SSDs (sold separately) in an x8 PCIe slot.

Fits in Almost Any Card Space

Low-profile card includes full-height (pre-attached) and low-profile PCIe brackets; fits in almost any computer or Thunderbolt expansion system with an available x8 PCIe slot.

High-performance PCIe Interface

PCI Express 3.0 x8 host bus interface plus connects four lanes of PCIe 3.0 bandwidth to each installed SSD.

Superior Performance

Achieve sustained single SSD speeds up to 3400 MB/s, RAID 0 speeds up to 6600 MB/s.

macOS Boot Support

Supports booting from a single (non-RAIDed) attached SSD.

No Thermal Throttling

Card design enables installed SSDs to maintain high performance during very large file transfer operations.

Optimized for Thunderbolt

SSD Ideas

macOS Boot Supporter. Applications’ Scratch Disk. Time Machine Backup.

Mac users can install macOS® on one SSD to create a 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 even for use as a Time Machine® backup volume.

Silent and Cool Running

No Slowdowns. No Thermal Throttling. Full Performance.

SSDs heat up significantly while performing very large file transfers and will protect themselves from overheating by “thermal throttling” — a feature that drastically cuts SSDs’ performance until they cool off to a safe level. The Sonnet M.2 2x4 Low-profile PCIe Card’s silent SSD cooling solution works to keep SSDs always cool enough to eliminate the need for thermal throttling and enables your SSDs to always maintain their highest potential performance.

Easy System Integration

Integrating a Sonnet M.2 2x4 Low-profile PCIe Card into your system is easy — NVMe compliance ensures the necessary drivers are installed automatically. The M.2 2x4 uses the operating systems’ built-in drive formatting utilities to format the SSDs. SSD health monitoring is supported through S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) data reporting, too.

Do You Need Something More?

More SSDs? More Connectivity?

Do you need to install more than two M.2 NVMe SSDs? Check out Sonnet’s M.2 4x4 PCIe Card with double the capacity and double the potential performance of the M.2 2x4 card. Or do you need more connectivity in addition to dual SSD support? Look at the McFiver™ PCIe Card; it offers the same performance of the M.2 2x4 card plus two 10Gbps USB-C® ports and a 10Gb Ethernet port.
