PCIe 4.0 x16 4-Bay M.2 NVMe Expansion Card with Silent DC Brushless Cooling Fan, M Key M.2 SSD Adapter Supports 2230/2242/2260/2280 NVMe Drives for PC Workstation NAS Server Storage Expansion

This PCIe 4.0 x16 quad M.2 expansion card expands one motherboard PCIe x16 slot into four independent M.2 NVMe slots, greatly boosting high-speed storage capacity for video editing workstations, NAS, gaming PCs and entry-level servers.

Each M.2 socket is assigned a dedicated PCIe 4.0 x4 channel, reaching a single-drive bandwidth up to 32GB/s; backward compatible with PCIe 3.0 motherboards. It only supports M-Key NVMe SSDs and accommodates all common compact sizes: 2230, 2242, 2260 and mainstream 2280.

To resolve overheating issues when four SSDs run heavy workloads simultaneously, the card adopts an advanced active cooling assembly. A large-area aluminum heat sink with thermal pads fully touches SSD controllers and memory chips, paired with a low-noise DC brushless fan for continuous airflow heat dissipation. It effectively avoids performance drops caused by high temperatures and extends SSD lifespan without creating distracting chassis noise.

The multilayer PCB is built with full electromagnetic shielding to eliminate signal interference and guarantee stable long-duration data transmission. Every slot comes with a separate LED light to show power status and read/write activity, making hardware inspection and fault diagnosis straightforward.

No complicated driver setup is needed for Windows 10/11 and most Linux systems. The card supports Intel VROC and AMD native NVMe RAID, perfect for building high-speed RAID 0 storage arrays for 4K/8K raw footage, massive databases and large file storage.
