PCIe 4.0 x16 4-Port M.2 NVMe Expansion Card with Ultra Quiet DC Brushless Cooling Fan, M Key M.2 SSD Adapter Supports 2230/2242/2260/2280 NVMe Drives for Desktop Workstation NAS Storage Upgrade

This high-performance quad M.2 PCIe 4.0 x16 expansion card lets you install up to four M-Key NVMe SSDs via a single PCIe x16 motherboard slot, massively expanding storage capacity for content creation workstations, high-capacity NAS, servers and gaming rigs.

Each M.2 slot gets an independent PCIe 4.0 x4 channel, delivering up to 32GBps bandwidth per SSD without lane bottlenecks, fully backward compatible with PCIe 3.0 systems. It universally supports mainstream M.2 NVMe drive lengths: 2230, 2242, 2260 and standard 2280.

Equipped with an advanced active cooling system: a low-noise DC brushless fan paired with full aluminum heat sink and thermal conductive pads directly contacts SSD controllers and NAND chips. Continuous airflow dissipates heavy heat generated by four NVMe drives under simultaneous sustained read/write loads, effectively preventing temperature-induced performance throttling and extending SSD service life. The fan operates at low decibel levels with minimal chassis noise for quiet office and studio environments.

No extra driver installation required for mainstream operating systems including Windows 10/11 and all Linux distributions. The card supports Intel VROC RAID and AMD native NVMe RAID modes, ideal for building high-speed RAID 0 storage arrays for 4K/8K video editing, large database processing and raw media storage. Individual LED indicators on each slot display real-time power and activity status for easy hardware troubleshooting.
