Independent, Stand Alone NVMe SSD Solution. Host Bus Type: PCIe 3.0 x16. Support Equipment: 4NVMe SSD for 2242,2260,2280 and 22110mm. STC PE3162-4I is a PCI Express x16 Gen3 PCIe switch Card provides dedicated PCIe 3.0 x4 (32Gb/s) bus bandwidth for each M. 2 SSD, and unlocks the true performance potential of NVMe based storage configurations. Ideal for servers & high-end desktop/workstation platforms, The all-aluminum casing naturally dissipates waste heat away from the SSD modules, and features an integrated fan and heat sink that work in conjunction to eject excess heat away from vital components and keep ambient temperatures manageable and cool. PLX PEX8747 Switch Controller has a PCIe 3.0 x16 upstream port as well as four PCIe 3.0 x4 downstream ports. Dedicated PCIe 3.0 x16 bus bandwidth fully maximizes AHCI/NVMe SSDs performance, And dedicated PCIe 3.0 x4 bandwidth for each NVMe M. This card does not rely on PCIe bifurcation supported by CPU or PCH. AHCI/NVMe RAID is supported base on the motherboard chipsets & macOS Disk Utility. Supports Windows 10 & Later, Windows 2016 Server, & Linux Kernel 3.3 & later.
