1. This PCIE-PEX8747M4 is a PCIE Gen 3.0 x4 to 4-Port NVME M.2 SSD expansion card that effectively expands 4x PCIE lanes from motherboard to 16x PCIE lanes by using 4x NVME M.2 physical slots. It provides 32Gb/s total bandwidth for 4x 32Gb/s max NVME M.2 SSDs on desktop PCs and NAS systems without requiring PCIE Bifurcation support, making it ideal for video editing, data storage, and gaming.
2. Active On-Card PCIe Bifurcation, Not Require Motherboard PCIE Bifurcation. The PCIE-PEX8747M4 is built on the Broadcom PLX PEX8747 PCIE Gen 3.0 switch. It draws 4x PCIE lanes (32Gb/s) from motherboards, expands to 16 PCIE lanes, then assigns these lanes into 4x PCIE Gen 3.0 x4 links (32Gb/s each) via 4x physical NVME M.2 slots. This enables users to install and run 4x NVME M.2 SSDs at full speed 32 Gb/s.
3. Host Interface: PCIE Gen 3.0 x4; Device Slot: 4x NVME M.2 Key-M slots; PCIE Upstream: PCIE Gen 3.0 x4, 32Gb/s; PCIE Downstream: 4x PCIE x4 links, 32 Gb/s max per NVME M.2 slot; M.2 SSD Form Factors: 2230, 2242, 2260, 2280, 22110; NVME Protocol: 1.3, 1.4, 2.0; RAID Function: No hardware RAID, software RAID supported; SSD Features: Supports data storage and UEFI (GPT) boot from NVME M.2 SSDs.
4. Plug-and-Play Compatibility: Windows: Windows 7, 8.x, 10, 11 64bit and Windows Server 2025, 2022, 2019, 2016, 2012 R2, and 2012 64bit. Virtualization: VMware ESXi, Proxmox VE, and other major hypervisors. Linux: Ubuntu, RHEL, Debian, and other kernel-based distributions. NAS: True NAS, Synology DSM, QTS, AiNAS, Unraid and more. MAC OS: Fully supported for storage expansion, NOT recommended boot.
5. Complies with PCIE Gen 3.0 (8GT/s/lane), delivering a total bandwidth of 32Gb/s and ensuring each NVME M.2 SSD achieves speeds up to 32Gb/s. Fully compatible with PCIE Gen 4.0 and Gen 5.0, operating at the card maximum native speed of 32Gb/s per drive. Backward compatible with PCIE Gen 2.0, providing a reduced bandwidth of 40Gb/s, with each NVME M.2 SSD capable of reaching up to 20Gb/s.
6. ATTENTION: 1. The PCIE-PEX8747M4 utilizes a PCIE x4 physical interface and will occupy one PCIE x4, x8 or x16 slot on the motherboard. 2. Supports NVME M.2 Key M SSDs only. Not compatible with M.2 Key B SATA SSDs. 3. NVME M.2 SSDs may generate substantial heat during operation. Ensure sufficient chassis airflow or install heatsinks on the NVME M.2 SSDs.
