PCIe 4.0 x8 Dual NVMe M.2 SSD Expansion Card – 1 to 2
Double Your NVMe Storage with One PCIe Slot
The PCIe 4.0 x8 1-to-2 NVMe Expansion Card lets you run two M.2 NVMe SSDs simultaneously from a single PCIe x8 slot — a fast, elegant upgrade for any desktop PC build. Whether you're expanding a workstation, gaming rig, or home server, this card unlocks maximum storage bandwidth without sacrificing motherboard real estate.
Made in Mainland China. CE, FCC, and RoHS certified.
Key Features
- 1-to-2 NVMe Expansion: Run two NVMe M.2 SSDs simultaneously on motherboards that support PCIe signal splitting; single-SSD mode (SSD1 slot) available on non-bifurcation boards.
- PCIe 4.0 x8 Interface: Fully backward compatible with PCIe 3.0 — get the highest throughput your system supports.
- Dual M.2 M-Key Slots: Supports M.2 NVMe form factors 2230, 2242, 2260, and 2280 — compatible with most modern SSDs.
- Gold-Plated PCIe Connector: The gold-finger contacts resist oxidation, ensuring reliable conductivity and a longer service life.
- Broad OS Support: Compatible with Windows 7, 8, 10, 11, Linux, and macOS.
- Internal Installation: Installs directly into your PC's PCIe x8 slot — no external power adapter required.
- High-Speed Data Transfer: PCIe x8 bandwidth unleashes the full read/write performance of your NVMe drives, cutting load times and boosting overall system responsiveness.

Frequently Asked Questions
Q: Does this PCIe 4.0 NVMe expansion card work with PCIe 3.0 motherboards?
A: Yes! The card is fully backward compatible with PCIe 3.0. You'll get speeds in line with PCIe 3.0 bandwidth when used in a PCIe 3.0 slot, and full PCIe 4.0 performance in a PCIe 4.0-capable slot.
Q: Can I use both M.2 NVMe slots at the same time?
A: Both slots are active simultaneously on motherboards that support PCIe bifurcation (signal splitting). On motherboards that do not support bifurcation, only the SSD1 slot will be recognized.
Q: Which M.2 SSD form factors are supported?
A: The card supports M.2 M-Key NVMe SSDs in 2230, 2242, 2260, and 2280 form factors. Note: SATA-based M.2 drives are not supported — NVMe protocol only.
Q: Do I need to install any drivers?
A: No additional drivers are required. The card is plug-and-play on Windows 7, 8, 10, 11, Linux, and macOS — your operating system will detect the NVMe SSDs automatically.
