  • Add four M.2 SSDs via a single PCIe x16 slot
  • Each drive reaches 7.8 GBps read and write speeds
  • Supports 2242, 2260, 2280 and 22110 mm NVMe drives
  • Vented bracket improves airflow for cooler operation
  • Works with software RAID such as Storage Spaces or mdraid

Quad M.2 PCIe Adapter Card

This adapter installs in a PCIe x16 slot to add up to four M.2 solid-state drives. It is intended for desktop, workstation or server builders who need extra high-speed storage capacity without occupying drive bays. The card itself contains no bridge chip, so the host system must support PCIe bifurcation for all four drives to be visible.

NVMe and AHCI drive support

The slot accepts M-key or B+M-key modules in 2242, 2260, 2280 and 22110 form factors. Each drive can deliver read and write speeds up to 7.8GBps when the platform provides sufficient lanes. Software RAID such as Windows Storage Spaces or Linux mdraid can combine the drives for redundancy or throughput, and no extra drivers are required beyond operating-system support for bifurcation.

Vented full-profile bracket

A pre-installed vented bracket promotes airflow across the installed modules to help manage thermals during sustained workloads. The card occupies a single x16 expansion slot and uses the standard rear-panel cut-out, so it fits typical chassis layouts without modification.

Questions about this item

Does the card require any maintenance such as fan cleaning or firmware updates over time?

The adapter has no onboard controller or active cooling, so no fan cleaning or firmware updates are needed.

What is the maximum sustained throughput each M.2 drive can reach on this card?

Each drive can deliver up to 7.8 GBps read and write when the host slot provides full PCIe x4 bandwidth.

How much heat does the card produce when all four SSDs run continuously?

The card itself is passive; heat comes from the SSDs and the vented bracket helps airflow to dissipate it.
