1、Support: Supports two M.2 SSDs simultaneously (one SATA interface and one NVMe interface). 2、Function: Convert an M.2 NVMe SSD (M Key) interface to a PCIe 3.0 x4 interface (compatible with PCIe 2.0), convert an M.2 SATA SSD (B Key) interface to a SATA interface (excluding the need to connect a SATA cable) . 3、PCB Porous Design: The heat on the PCB can also be quickly dissipated through the heat dissipation holes. Support slot: PCIE 4X/8X/16X slot. 4、Support M.2 SSD Size: 22x30, 22x42, 22x60, 22x80, 22x110mm, support various lengths, free expansion, practical and convenient. 5、Stable: With elastic connector, make the contact more stable. The thickened immersion gold PCB gold plated version is more durable and stable than the tin sprayed version, especially for high speed signal transmission, which has better continuity and stability. Explosion proof solidity capacitors, all solidity capacitors, high performance high quality electronic components solidity capacitors are environmentally friendly, low impedance, high and low temperature stability.
