Interface type:Supported protocols: PCIe Gen3x4 (up to 32Gb/s) and SATA3 (6Gb/s) Size compatibility: 2260/2280 specification M.2 module (length 22mm, width 60/80mm) Slot key: Key M (supports PCIe and SATA). Please note that SSDs with mixed Key B/M keys should be distinguished. PCIe mode: theoretical bandwidth up to 3.94 GB/s (32 Gb/s), suitable for NVMe SSDs (such as Samsun 980 and Western Digital SN570) SATA mode: Bandwidth limit 600 MB/s, suitable for budget-limited SATA M.2 hard drives installation: Remove the screw next to the motherboard's M.2 slot (usually located near the PCIe slot). Insert the SSD into the slot at an angle of approximately 30° and press down gently until it snaps into place. Use a screwdriver to tighten the screws to prevent the SSD from shaking download.asr... Things to note: If you use a PCIe 4.0 SSD , performance will drop to PCIe 3.0 levels. Some SSDs require an additional heat sink. Since the motherboard is not equipped with an active cooling module, it is recommended to choose a model with a built-in heat sink (The product printed words may vary depending on the batch, but this does not affect use) Color: As Shown Material: PCB Package Contents: 1 * H510M-HDV /M.2 SE Motherboard
