Specification:

• Microsemi's Switchtec PM8562 PFX-L 32xG3 Chip Controller has a PCIe 3.0 x16 upstream port as well as four PCIe 3.0 x4 downstream ports. The switch is designed primarily for storage devices, enabling installation of four AHCI/NVMe drives on a single card.
• This card uses PM8562 PCIe switches and therefore does not rely on PCIe bifurcation supported by CPU or PCH (i.e., they will work on closed end systems that have limited PCIe bifurcation capabilities) as well as on software RAID technologies supported by the platform.
• Dedicated PCIe 3.0 x16 bus bandwidth fully maximizes AHCI/NVMe SSDs performance 
• Delivers unprecedented fast transfer speed via intelligently aggregated Dual x16 PCIe 3.0 bus bandwidth
• Support Main Board with PCI-Express 3.1 /3.0 /2.0 Slot 
• AHCI/NVMe RAID is supported base on the motherboard chipsets & macOS Disk Utility

*Actual performance may vary based on hardware, software, and overall system configuration.
