Ultra-fast Gen4 SSD Data Transfers

Speed or capacity? Not too long ago, you had to make a choice between the two. The problem is, for many professional workflows, both are critical. Everyone knows M.2 NVMe PCIe SSDs offer great performance, but limited capacity. Hard drives offer great capacity, but very slow speeds by comparison. What if you could create increased SSD capacity? We make it possible — the Sonnet M.2 8x4 Silent Gen4 PCIe® Card enables you to mount up to eight NVMe SSDs into a single x16 PCIe card slot and combine their capabilities for ultra-performance. This card can transform your workflow.

Not Quiet…Silent

Sonnet Silent Cooling Thwarts Thermal Throttling

Sonnet designed the M.2 8x4 Silent Gen4 PCIe Card with an effective passive cooling solution – instead of relying on fans that can get loud, Sonnet silent cooling effectively presents thermal throttling, enabling SSDS to maintain sustained peak performance without a peep.

Easy System Integration

Integrating a Sonnet M.2 8x4 Silent Gen4 PCIe Card into your system is easy — NVMe compliance ensures the necessary drivers are installed automatically. The M.2 8x4 uses your computer’s operating system’s 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.

* Only in a 2023 Mac Pro (M2 Ultra), the initial release of macOS 14 (Sonoma) does not properly access the data in the M.2 8x4 PCIe Card. Users with macOS 13 installed should not update to macOS 14 at this time. We expect Apple to fix this anomaly in an update. (The data will not be lost, just inaccessible.) The card will continue to work fine under macOS 14 in an Intel Mac Pro, or with any Mac using a Thunderbolt expansion system.
