Dual M.2 PCIe 3.0 x4 Expansion Card, Supports NVMe M-Key & SATA B-Key SSDs, Compatible with 2230/2242/2260/2280/22110 NGFF Drives, Desktop PCI Express Storage Adapter Host Controller

This dual M.2 PCIe 3.0 x4 host controller expansion card is an all-in-one multi-drive storage upgrade accessory for desktop computers. It carries two independent M.2 slots: one M-Key slot exclusively for PCIe NVMe SSDs and one B-Key slot for SATA protocol M.2 SSDs, enabling users to expand two high-speed storage devices through a single PCIe slot.

The adapter supports the full range of common M.2 sizes including the extended 22110, covering all mainstream consumer and industrial SSD specifications. Built with multi-layer shielded PCB and gold-plated contacts, it effectively reduces electromagnetic interference and signal attenuation, maintaining full PCIe 3.0 x4 bandwidth for NVMe drives and stable SATA transfer speeds under continuous heavy workloads such as video editing, large database storage and game library expansion.

Comes with a standard full-height metal mounting bracket compatible with most ATX/MATX/ITX PC chassis. Plug-and-play design seamlessly supports Windows and Linux operating systems without complicated driver installation, with matching SSD fixing screws supplied for secure installation.

Ideal for content creation workstations, gaming desktops and office PCs with limited native motherboard M.2 interfaces to maximize storage capacity at low cost.
