Dell Dual M.2 Slot NVMe SSD PCIe Boss Controller Adapter

The Dell K4D64 is a PCIe adapter card that gives any compatible server or workstation two additional NVMe storage lanes. By hosting a pair of M.2 sockets on one expansion board, it lets you add high-speed solid state drives without removing existing storage or using external enclosures.

Each slot accepts drives built to either the 2280 or the 22110 length standard, so you can match capacity and endurance to the workload at hand. Because the adapter connects directly through PCIe, data flows between the CPU and the drives with very little latency, a benefit that shows up in database transactions, virtual machine hosting, and real-time media editing.

The card follows a low-profile design that slides easily into chassis built for dense rack deployments as well as into compact tower systems. Installation is straightforward: seat the board in an open PCIe slot, secure the bracket, boot the system, and let the operating system recognize the new NVMe devices. Windows, macOS, and Linux all provide native support, so no extra drivers or cables are involved.

Whether you are expanding an existing storage pool, building a cache layer for frequently accessed data, or giving a development workstation faster compile times, the Dell K4D64 offers a tidy path to modern NVMe performance in a familiar PCIe form factor.

Highlights:

• Provides two independent M.2 NVMe slots for 2280 or 22110 drives
• Connects through a standard PCIe interface for direct, low-latency data transfer
• Low-profile board that fits rack mount and compact tower systems
• Works out of the box with Windows, macOS, and Linux
• Ideal for servers, workstations, and any environment that needs fast local storage
