InLine 76660R Internal U.2 Interface Card PCIe Male 4 Gbit/s

The InLine 76660R is an internal PCI Express expansion card that provides four internal U.2 (SFF-8639) NVMe SSD slots. It connects to a PCIe 3.0 x16 slot and supports automatic lane detection (bifurcation) so multiple NVMe drives can operate in parallel at full PCIe bandwidth. Each U.2 port supports transfer rates up to 4 GB/s and the card includes LED indicators for read/write activity. The card is natively supported by Windows and major Linux distributions and requires no additional driver.

Advantages

The card enables parallel operation of up to four 2.5-inch NVMe SSDs with a total maximum PCIe bandwidth of up to 128 Gb/s. Automatic lane detection simplifies system integration and reduces manual configuration. Onboard LEDs provide easy status and fault diagnosis. The U.2 drives receive power directly from the PCIe bus, eliminating the need for separate power cables.

Suitable for

• High-performance storage expansion in desktops and workstations
• RAID arrays or multi-drive NVMe setups (requires motherboard bifurcation support)
• Data-intensive applications such as virtualization, databases, or video editing
• Systems running Windows or Linux that need internal U.2 NVMe connectivity

Key specifications

• Model: InLine 76660R
• Bus: PCIe 3.0 x16 (8 GT/s) — up to 128 Gb/s bandwidth
• Connectors: 4 × SFF-8639 (U.2) for 2.5-inch NVMe SSDs
• Chipset: PI6C20400BLE
• Data rate: Up to 4 GB/s per port
• Dimensions: 288 mm × 122 mm (PCIe board)
• Operating temperature: -40 °C to +85 °C

How to use

Install the card into a free PCIe 3.0 x16 slot on a compatible motherboard and secure it with the supplied screws. Insert up to four SFF-8639 (U.2) NVMe SSDs into the connectors. Ensure the system BIOS/UEFI is configured for PCIe bifurcation (for example x16 -> x4/x4/x4/x4) if you want all drives to be recognized and used simultaneously. The drives receive power through the PCIe bus; no additional power cables or drivers are required for supported operating systems.

Usage recommendations

Check your motherboard manual for the exact BIOS/UEFI setting name (such as "PCIe Bifurcation", "Lane Splitting" or "PCIe Slot Configuration") and confirm the board supports bifurcation. Verify OS compatibility (Windows 11/10/8/7, Windows Server 2012 R2, or supported Linux distributions) and test drive recognition after changing BIOS settings.
