This Dual M.2 PCIe SSD Adapter adds two high performance PCIe M.2 SSDs (NVMe and AHCI) into the PCIe x8 or x16 slot of a desktop, workstation, or server. Boost System Performance Take full advantage of the fast performance and compact size of PCIe M.2 internal solid-state drives, with read and write speeds up to 7.8GBps per drive. Access two M.2 PCIe SSDs simultaneously No on-board chip leads to wide system compatibility. This card requires PCIe bifurcation, meaning it easily integrates into any system with an available x8 or x16 PCIe slot that supports PCIe bifurcation. Utilize software RAID, such as Storage Spaces (Microsoft) or mdraid/mdadm (Linux), to build a RAID array, adding redundancy or enhancing system performance. Wide Compatibility The PCIe M.2 NGFF (M Key or B+M Key) adapter supports PCIe NVMe and PCIe AHCI M.2 SSDs including 2242, 2260, 2280 and 22110mm drives. The PCIe M.2 Adapter Card does not require any software or drivers, meaning it works with most operating systems, if the computer/motherboard supports bifurcation. Vented Brackets The included full and low-profile vented brackets increase air flow to improve heat dissipation, which aids in maintaining optimal and reliable operating temperatures.
