Detailed Specifications
StarTech QUAD-M2-PCIE-CARD-B 4 Port M 2 NVMe SSD Adapter Card
Overview
The StarTech QUAD-M2-PCIE-CARD-B is a high-performance PCI Express expansion card designed to add up to four M.2 NVMe Solid State Drives (SSDs) to a desktop or server through a single PCIe x16 slot. This hardware is an ideal solution for data-intensive professionals, such as video editors, database administrators, and software developers, who require massive storage throughput and ultra-low latency for demanding local workloads.
This adapter utilizes PCIe bifurcation to provide dedicated bandwidth to each of the four SSDs. It is important to note that the host motherboard must support PCIe bifurcation (splitting the x16 slot into x4/x4/x4/x4 mode) to recognize all four drives. When properly configured, this allows for the creation of high-speed RAID arrays or the use of multiple independent bootable volumes. By moving storage directly to the PCIe bus, the QUAD-M2-PCIE-CARD-B bypasses the limitations of traditional SATA interfaces, enabling read/write speeds that can reach the full potential of Gen 4 or Gen 3 NVMe drives.
Built for thermal efficiency and long-term reliability, the card features a large aluminum heatsink and integrated thermal pads that cover all four SSD slots. This passive cooling design is essential for preventing thermal throttling during sustained high-speed data transfers. The card supports a wide variety of M.2 drive lengths, including 2230, 2242, 2260, 2280, and 22110, ensuring compatibility with virtually any enterprise or consumer NVMe SSD on the market.
