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 ). 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 SN570) mode: Bandwidth limit 600 MB/s, suitable for budget-limited 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 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 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 depending on the batch, but this does not affect use) Color: As Shown Material: PCB Package Contents: 1 * H510M-HDV /M.2 SE Motherboard Only the above package content, other products are not included.
