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 — 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.
