Motherboard BIOS must support PCIe bifurcation (x16 to 2x8), otherwise only the first drive will be detected. Backward compatible with PCIe 3.0 / 2.0. Recommended for PCIe 4.0 -enabled CPUs ^^ PCIe 4.0 x16 to dual SFF-8654 adapter card, supporting two U. 2 NVMe SSDs with 8-lane PCIe 4.0 bandwidth per port (theoretical 6.9GB /s per port). Requires SFF-8654 to SFF-8639 cable (sold separately) ^^ Designed for NVMe SSDs only (no SAS/SATA support). Ideal for data centers, server storage expansion, and high-performance workstations. Supports hot-swap (requires compatible backplane) ^^ Includes full-height and low-profile brackets.
Requires a separate SFF-8654 to U. 2 (SFF-8639) cable ^^ Compatible with Windows, Linux, and VMware
