Sonnet M.2 2x4 Low-profile PCIe Card

Two M.2 NVMe SSD slots - Add your own SSDs up to 16TB

Add up to 16TB of SSD Storage! 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.

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.

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.

Silent and Cool Running – No Slowdowns. No Thermal Throttling. Full Performance.

SSSDs 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.

Thunderbolt Port? – Connect Two SSDs Through One Cable

Got a Thunderbolt connection, but no PCIe card slot? Sonnet’s M.2 2x4 Low-profile PCIe Card is ideal for use in any one of Sonnet’s Thunderbolt expansion systems. The combo enables you to add one or two SSDs to any Mac (M series, Intel®), Windows, or Linux computer with Thunderbolt ports.

Simple and S.M.A.R.T. – 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.
