1、Expansion Card: M.2 NVME (M Key) SSD to PCIe expansion card. The M.2 NVMe to PCIe adapter adds NVMe SSD hard drives to your computer's desktop for perfect performance. 2、Compatibility: Compatible with M.2 SSD (PCIe NVMe): 80x22mm, 60x22mm, 42x22mm, 30x22mm, four-speed design, supports various lengths, free expansion, practical and convenient. The porous design on the PCB allows the heat on the PCB to be quickly dissipated through the heat dissipation holes. 3、PCIe3.0 x4: Support for PCIe x4 / x8 / x16 slot. Explosion-proof solid capacitors, all solid capacitors, high-performance high-quality electronic components, solid capacitors are environmentally friendly, low impedance, high and low temperature stability. M KEY high quality with elastic contact, makes the contact more stable. Smart LED indicator light, always on when the card is connected and flashes when reading and writing. 4、Support: Support for NVMe SSD, such as for 950Pro/960EVO/XP941/PM951/PM961/SM951/SM961, for Plextor M6e series, for M.2 SSD, etc. 5、Material: Thickened immersed gold PCB gold-plated version is more durable and stable than tin-sprayed version, especially for high-speed signal transmission, it has better continuity and stability. PCLE 3.0 architecture, the theoretical speed of single-channel (X1) unidirectional broadband is close to 1 GB/S, and the theoretical speed of 4-channel (X4) bidirectional broadband can reach 8 GB/S. Item Type: M.2 To Pcie Adapter Product Material: PCB Support Hard Drive: M KEY M.2 (NGFF) Interface Supported Operating Systems: for Windows, for OS, for Linux Support Slot: PCIE 4X/8X/16X Slot 1 x M.2 To Pcie Adapter 1 x Screw 1 x Nut
