PC expansion hardware that turns a PCIe x16 slot into four active M.2 NVMe bays for high‑speed local storage. Plyisty M.2 NVMe to PCIe 4.0 X16 Adapter suits editors and workstation builders who need compact, high‑throughput storage. Will motherboard and BIOS requirements make it practical for most builds?
⚡ At a Glance
- • Transfer Speed: Four NVMe lanes at 32Gbps each via a PCIe 4.0 x16 interface
- • Best for: Workstation builders and content creators needing compact multi‑SSD arrays
- • Not ideal for: Systems whose motherboards do not support PCIe bifurcation
Quad-bay expansion card supports M.2 NVMe sizes from 2230 to 22110. Requires motherboard BIOS bifurcation and compatible CPU/motherboard PCIe 4.0 support.
Massive local storage expansion - With four M.2 NVMe bays
Supports installation of four M.2 NVMe SSDs, compatible with 2230, 2242, 2260, 2280 and 22110 form factors, allowing simultaneous access to all drives. The card plugs into a PCIe x16 slot and exposes each M.2 bay to the host when bifurcation is enabled in BIOS.
Consolidate multiple NVMe drives in a single expansion slot for large, fast scratch storage. Useful for editing large video files or managing multiple project volumes without external enclosures.
High throughput for demanding workloads - Thanks to PCIe 4.0 x16 interface
Operates with a 4G x 32Gbps signal over a solid PCIe x16 interface and supports PCIe 3.0 and 4.0 transfer protocols. Full PCIe 4.0 speed requires a CPU and motherboard that support PCIe 4.0; CPUs below 11th generation may not support PCIe 4.0.
Deliver very fast sequential transfer rates ideal for large-file transfers and scratch disks. Suitable where short load and transfer times materially speed up workflows.
Flexible RAID and OS support - With driver-enabled soft RAID on some systems
Windows 10 can realise software RAID via supplied drivers, while other operating systems may require driver installation. CPU-based RAID (VROC) requires an additional licence and OS X Pro 5.1 is not supported.
Set up RAID arrays for extra performance or redundancy on supported systems, but check OS and driver requirements beforehand. Ideal for users who want software RAID without buying dedicated RAID hardware.
✨ The 4 Key Reasons for Plyisty M.2 NVMe to PCIe 4.0 X16 Adapter
Supports multiple M.2 sizes - Fit 2230–22110 SSDs for flexible storage and drive choices
Windows 10 soft RAID - Combine drives for speed or redundancy using included drivers
Requires PCIe bifurcation - Ensures all four ports are addressable in BIOS-capable motherboards
Broad OS compatibility - Plug-and-play on Windows, Linux and OS X; Windows 7 unsupported

❓ Frequently Asked Questions
Q: Will my motherboard recognise all four M.2 SSDs?
A: Only if the motherboard supports PCIe bifurcation for the slot used. Without bifurcation, only the first NVMe port may be recognised.
Q: Which M.2 sizes are supported?
A: Supported sizes are 2230, 2242, 2260, 2280 and 22110 for M.2 NVMe SSDs.
Q: Can I set up RAID with this card?
A: Windows 10 can use software RAID with the appropriate driver; other systems may require drivers and CPU-based RAID (VROC) requires a separate licence.
🏆 Our Verdict
Best suited to workstation builders and content creators who need compact, high‑speed local storage for large files and scratch volumes. Hosting four M.2 NVMe SSDs on a single PCIe x16 link and support for software RAID on some systems are the standout advantages. While the upfront investment can be significant, the flexibility and long‑term performance make it a practical upgrade for demanding workflows.
