Adds four NVMe M.2 slots via a PCIe 3.0 x16 interface with Intel VROC and AMD Threadripper RAID support, up to 128 Gbps bandwidth, and a 14 W power phase plus active cooling
This ASUS expansion card adds four M.2 Socket 3 M-Key slots to a desktop system. It accepts NVMe drives in 2242, 2260, 2280 and 22110 lengths. The card plugs into a PCI Express 3.0 x16 slot and also works in x8 or x16 mechanical slots. A built-in heatsink and blower-style fan keep all four drives cool under heavy load.
The card is designed for users who want a bootable NVMe RAID array using Intel VROC on X299 or Z370 motherboards, or AMD Ryzen Threadripper on X399, X470, B450, X370 or B350 boards. It requires CPU-attached PCIe lanes and platform RAID support. Builders without a compatible Intel or AMD Threadripper platform cannot use the RAID features and should look at a different controller.
The card delivers up to 128 Gbps of combined bandwidth across the four slots when the platform provides enough PCIe 3.0 lanes. Its two-phase power design supplies up to 14 W to each installed drive, ensuring stable operation for high-performance NVMe SSDs.
