ST558 8-Bay M.2 NVMe to PCIe 4.0 x16 Adapter, PEX88048 Switch

8X M. 2 NVME ON ONE PCIe 4.0
X16 SLOT: Expand your workstation, NAS or rackmount server with eight M. 2 Key-M NVMe SSDs through the PEX88048 PCIe 4.0 switch (50 lanes), delivering up to 256Gb/s (32GB/s) shared bandwidth. Supports 2280-form-factor NVMe SSDs; backward compatible with PCIe 3.0 at native speeds.;
NO BIFURCATION REQUIRED: The onboard PEX88048 switch chip splits the PCIe 4.0 x16 slot internally, so it works with all motherboards - no BIOS bifurcation setting needed, including Mac Pro. No extra power cable required; the card is powered entirely by the PCIe slot.;
FULL-COVERAGE COOLING: Oversized aluminum heatsink cover wraps the switch chip and all eight M. 2 SSDs, with a built-in fan driving continuous airflow - eight full-speed NVMe SSDs stay cool under sustained load without throttling, no tuning required.;
SOFT RAID & STORAGE EXPANSION: Build RAID 0/1/5/10 with Windows Disk Management, Storage Spaces, Linux mdadm or macOS - ideal for NAS backup targets, video editing scratch disks, surveillance storage and homelab use. Intel VROC requires a separate license.; PLUG & PLAY, LIMITATIONS
STATED: Driver-free on Windows 11/10/8, Linux and macOS (Windows 7 not supported). New SSDs need initialization and formatting.
Note: OS booting from the attached SSDs is not supported - use as high-speed data storage. Regular bracket included.
