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 is 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.
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.
Did you know that that there are less expensive competitors cards on the market but none of the competitors have what Sonnet has:
A heat sink that is designed specifically to ensure that there is no thermal throttling which is reducing the speed of the data transfer when you need it most.
When you transfer data with large files (during those times the card heats up the most)
We have a high-capacity controller that is supported by 8 lanes of PCIE giving maximum bandwidth to each card and enabling up to 6600MB/s

- Technical Notes You may install any number of SSDs now and add more later without needing to reformat existing ones. This product’s performance will vary based on the type and number of SSDs used, the CPU speed, and the PCIe architecture. macOS 13 and macOS 14 do not currently support NVMe SSDs installed in a PCIe slot of the Mac Pro 7,1 (2019). Sonnet is working with Apple to resolve the issue.
