StarTech Quad M.2 PCIe Adapter Card PCIex16 QUADM2PCIECARDB

The StarTech QUADM2PCIECARDB is a PCIe x16 adapter that adds support for up to four M.2 PCIe SSDs, making it suitable for desktop and workstation users who want to expand internal storage through a compatible system with PCIe bifurcation.

Recommended For

• Desktop workstation or server owners with a PCIe x16 slot that supports bifurcation who want to add up to four PCIe M.2 SSDs through one card.
• NAS, home-server, or lab builders who want several NVMe drives available individually or in a software RAID array, and can configure bifurcation in their motherboard or system.
• Workstation users who need multiple PCIe SSDs for storage-heavy projects, such as keeping separate fast drives for active files, scratch space, or application data.
• PC builders with compatible PCIe AHCI or NVMe M.2 drives in 2242, 2260, 2280, or 22110 sizes who want to consolidate them on an add-in card.

Real-World Use Scenarios

• In a desktop, workstation, or server with a compatible PCIe slot, add up to four M.2 SSDs when motherboard slots are already occupied; the drives become available as additional storage.
• Build a software-managed storage pool or RAID array from multiple M.2 drives for a server or storage-focused PC; the user configures it in tools such as Windows Storage Spaces or Linux mdadm.
• Keep several SSDs available as separate volumes for different projects, applications, or data sets; the card provides drive connections, while the operating system manages the volumes.
• Expand fast local storage in a homelab or small server without replacing the motherboard; first confirm the motherboard supports PCIe bifurcation, or all four drives may not be detected.
