Upgrade your system speed and performance with this Dual M.2 PCIe SSD Adapter. It lets you add two high performance, enterprise-class PCIe 3.0 M.2 SSDs (NVMe and AHCI) into the PCIe 8-lane or larger slot of your desktop workstation or server. 

Boost System Performance 

The expansion card lets you take full advantage of the fast performance and compact size of PCIe M.2 internal solid-state drives. With the M.2 PCIe based drives in place, the adapter increases your storage capacity and gives your computer a significant speed boost, enhancing data transfer rates. 

Access two M.2 PCIe SSDs simultaneously 

The dual M.2 to PCIe expansion card employs a high-speed ASM2824 switch, allowing you to access two drives at the same time. Since the adapter card does not rely on PCIe bifurcation, it can easily be integrated into all systems, new and legacy.    

The M.2 PCI express adapter also gives you the flexibility to access your M.2 PCIe SSDs individually. Or, you can utilize software RAID to build a RAID array to add redundancy or enhance system performance. 

Wide System Compatibility  

The adapter connects directly to your computer motherboard to support two PCIe M.2 SSDs through a x8 PCIe expansion slot. The adapter is compatible with PCIe 3.0 motherboards and is backward compatible with PCIe 2.0 and PCIe 1.0. 

Supports a Wide Range of PCIe M.2 SSDs 

The PCIe M.2 NGFF (M Key) adapter supports PCIe 3.0 NVMe and PCIe-AHCI M.2 SSDs including 2242, 2260, and 2280 drives, supporting the most common drive sizes: 42, 60, and 80 mm lengths. 

Easy to Install 

The expansion card comes with a full-profile bracket pre-installed, and includes a half-height / low-profile bracket, for installation in small form-factor computers. 

Vented Brackets 

Vented brackets on the PCIe M.2 NGFF SSD adapter card increases air flow to assist in heat dissipation. 

The TAA compliant PEX8M2E2 is backed by a StarTech.com 2-year warranty and free lifetime technical support. 


  • Connect two PCIe M.2 SSDs to your desktop computer or server to boost system speed and increase internal data storage
  • Get ultra-fast data access, ideal for high-performance workstations
  • Install your operating system on an M.2 PCIe based drive for fast access, while keeping larger platter drives available for bulk storage

Great x8 M.2 adapter card

By: Jason57 - 01/22/2021
Used in Mac Pro 5,1 to boot single NVMe M.2 drive. I am booting MacOS Mohave (system BootROM from Samsung 970 EVO. Seeing 23xx MB/s write and 28xx MB/s read on 12 core dual 2.66 MHz Mac Pro (2012), using Blackmagic Disk Speed Test app. This is a great option if you’re planning to run a single NVMe drive that needs x8 PCIe 2.0 to accommodate an x3 PCIe 3.0 drive.
