The SilverStone SST-ECM40 PCIe 4.0 x16 Quad M.2 NVMe SSD Adapter Card unlocks blazing-fast storage expansion for high-performance systems. Supporting up to four M.2 NVMe SSDs, it leverages PCIe 4.0 x16 bandwidth for ultra-high-speed data transfer, making it ideal for gaming, content creation, and enterprise workloads. Featuring an integrated aluminum heatsink for efficient thermal management, the ECM40 ensures optimal performance under heavy loads. With a plug-and-play design and broad compatibility, this adapter is the perfect solution for maximizing storage speed and capacity in PCIe-equipped desktops and workstations.
Features
ECM40
PCIe 4.0 x16 to 4 x M.2 NVMe SSD Adaptor Card
- Support 4 x NVMe M.2 SSD (M Key) via PCIe x16 interface
- Supports M.2 SSDs in 2230, 2242, 2260, and 2280 form factors
- 40mm x 40mm dual ball bearing cooling fan
- Cooling fan On/Off power switch
- Data centre-grade reliability
- Support USAP and TRIM
* The motherboard or add-on card must support PCIe bifurcation, allowing the PCIe x16/x8 slot to be split into 4x4 or 4x2 configurations.
High-Speed Expansion
The ECM40 can accommodate a total of 4 NVMe M.2 SSDs (M Key), operating via a PCIe x16 lane transfer rate.
Supports Various Form Factor M.2 SSDs
Each M.2 SSD slot can accommodate 2230mm, 2242mm, 2260mm, or 2280mm.
Exceptional Cooling Efficiency
Running 4 M.2 SSDs can generate significant heat during operation, so an integrated 40mm dual ball-bearing fan, ensuring each drive maintains optimal operating temperatures.
A cooling fan On/Off power switch featured allows users to manually control the cooling fan, enabling them to turn it on or off based on their cooling needs or power preferences.

| Remark |
1. Please confirm first whether your motherboard supports PCI-E Bifurcation..
2. The system requires PCI-E Bifurcation to add one more SSD, with full 16 lanes (x4/x4/x4/x4) needed for three or four drives, or x8/x8 (or x4/x4 for two drives). Ensure that the CPU can support the necessary PCI-E Bandwidth. It's recommended to contact your motherboard manufacturer to confirm bifurcation support to avoid the system recognising only one M.2 SSD.
3. The ECM40 does not support hardware RAID. For Windows 10 or newer, RAID functionality may require third-party software. It’s recommended to use four identical SSDs to set up the RAID array. |
