Description Specifications: Dual NVMe PCIe adapters allow you to add two M.2 NVMe SSDs to the motherboard through a single PCI-e x8 slot The dual NVMe to PCIe adapter uses the ASMedia ASMedia ASM 2812 chipset, which does not depend on the PCIe fork supported by MOBO. Each SSD uses PCI-e 3.1 x4 channels separately, without interference. (The final speed depends on the PCI-e bandwidth of SSD and Mobo) Compatible with M.2 SSD (PCI-e NVMe): all sizes 110x22mm, 80x22mm, 60x22mm and 42x22mm. Hardware requirements: PCI-e 8x/16x slot is provided on the motherboard, which is compatible with PCI-e 3.0/2.0/1.0 standar Please note: 1. This M.2 PCIe adapter can only support M Key Nvme SSDs based on M.2 PCI-e, and does not support PCI-e M Key AHCI SSDs, SATA-based B+M Key or B Key SSDs. 2. If "Disk Management" or "Device Management" cannot display the SSD, please download the SSD driver from the brand official website. 3. The old MB cannot support booting from "NVMe". Please confirm the MB specification 4. The cost per SSD is PCI-e 3.1 x4 channels, not the entire PCI-e 3.1x8 M, 2 NVMe Adapter allows you to use SSD alone, accelerate to the storage pool or perform RAID configuration of the operating system or third-party software in the storage pool. Hardware RAID is not supported Hardware requirements: 1x A available PCI-e 3.1 x8/16x slots, backward compatible PCI-e 3.0/2.0/1.0 Wide compatibility: Compatible with all M.2 NVMe SSDs (22110, 2280, 2260, 2242, 2230), not applicable to SATA-based B+M Key SSDs Chipset: ASMedia ASM2812, supporting non-forked motherboard Software: No driver required Color: black Material: plastic+metal Size: 18 * 5.5cm/7.09 * 2.17inch Manual measurement may have deviation Please ensure that the parts you want are the same as those shown in our pictures, otherwise they will not be suitable.
