Dual M.2 NVMe / Ahci | PCIe 4.0 x8 or x16 Slot | BifurcationThis 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 PerformanceTake 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 simultaneouslyNo 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 CompatibilityThe 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.
