Quad M.2 RAID Expansion Card

The Syba SI-PEX40161 installs into a PCI-Express 3.0 x16 slot and provides four M.2 2280 connectors for NVMe solid-state drives. It is built for workstation and server builders who want to combine multiple drives into a single bootable RAID volume using CPU-attached PCIe lanes. Intel VROC and AMD Ryzen Threadripper platforms are explicitly supported for array creation and management.

Sustained Load Power Delivery

A two-phase power circuit supplies up to 19.8 Watt to the installed drives, helping maintain stable voltage when all four SSDs operate at peak throughput for extended periods. This design reduces the risk of throttling or disconnection during heavy write workloads such as video ingest, database commits or large dataset preprocessing. Each drive receives dedicated power through the onboard regulation rather than relying solely on the slot.

Platform And Slot Verification

Confirm that your motherboard and CPU expose enough PCIe 3.0 lanes to run the card at x16 and that the BIOS or UEFI firmware includes Intel VROC or AMD Threadripper RAID option ROMs for bootable arrays. Consumer platforms with limited lane counts or missing RAID firmware will not support the advertised bootable NVMe RAID functionality. The card requires a full-size x16 mechanical slot and adequate case clearance for the installed M.2 modules.

Preguntas sobre este artículo

How much power can the 19.8 W two-phase supply deliver to four M.2 2280 drives under sustained load?

The on-board two-phase design is rated for up to 19.8 W total output, which is shared across all four M.2 2280 slots when drives run continuously.

Which CPU and platform combination must I already have to create a bootable NVMe RAID array with this card?

You need either an Intel platform with VROC support or an AMD Ryzen Threadripper CPU that exposes enough PCIe 3.0 lanes for the x16 link.

Will the x16 edge connector negotiate down to x8 or x4 if my motherboard only wires the slot for fewer lanes?

The card uses a PCIe 3.0 x16 interface; lane negotiation depends on the motherboard slot wiring and the CPU’s available PCIe 3.0 lanes.
