PCIe X16 to M.2 NVMe 4-Slot RAID Expansion Card – PCIe 4.0
PCIe X16 to M.2 NVMe Quad-Slot RAID Expansion Card
Unlock the full potential of your PC or 2U server with this high-performance PCIe X16 to M.2 NVMe Converter Card. Designed for enthusiasts, content creators, and server builders alike, this bifurcation expansion card lets you run four M.2 NVMe SSDs simultaneously at full X4 channel speeds — delivering blazing-fast RAID read speeds of up to 14,000+ MB/s with PCIe 4.0.
Made in Mainland China.
Key Features
- 4 Full-Speed X4 NVMe Slots: Front and rear-facing slots accommodate four M.2 M-Key NVMe SSDs simultaneously, each running at full PCIe X4 bandwidth — no compromises, no sharing.
- PCIe 4.0 Bifurcation Support: Harnesses your motherboard's PCIe signal splitting (bifurcation) to distribute bandwidth across all four drives — requires a motherboard that supports PCIe bifurcation.
- RAID Ready: Supports hardware RAID configurations for increased data throughput, redundancy, or striping setups — ideal for NAS, workstations, and 2U server builds.
- Broad SSD Compatibility: Supports M.2 M-Key NVMe SSDs in 2230, 2242, 2260, 2280, and 22110 form factors, giving you maximum flexibility in drive selection.
- Dual Bracket Included: Ships with both half-height and full-height brackets so it fits standard desktop towers and slim 2U server chassis with ease.
- M.2 PCIe Protocol Support: Compatible with M.2 PCIe protocol expansion cards and devices, making it a versatile hub for your storage ecosystem.

Frequently Asked Questions
Q: Does my PC support this PCIe X16 to M.2 NVMe expansion card?
A: Your motherboard must support PCIe bifurcation — specifically X4X4X4X4 lane splitting — through BIOS or UEFI settings. Most modern high-end and enthusiast-grade motherboards (Intel X299, X570, X670, TRX40, server boards, etc.) support this. Please check your motherboard manual or manufacturer's website to confirm bifurcation support before purchasing.
Q: Can I use M.2 SATA SSDs with this card?
A: No. This converter is designed exclusively for M.2 M-Key NVMe (PCIe protocol) SSDs. M.2 SATA-based drives are not compatible and will not be recognized by the card.
Q: What M.2 SSD sizes fit in this card?
A: The card supports M.2 NVMe SSDs in the following form factors: 2230, 2242, 2260, 2280, and 22110, giving you flexibility to use nearly any standard M.2 NVMe drive available on the market.
Q: What kind of RAID speeds can I expect?
A: With four PCIe 4.0 NVMe SSDs installed and a compatible bifurcation motherboard, RAID read speeds can exceed 14,000 MB/s, making this ideal for video editing workstations, data-intensive server tasks, and high-throughput computing environments.
