Three-slot M.2 adapter for desktop and server builds

This PCI Express 3.0 x4 card adds one NVMe slot and two SATA III slots to a system that lacks native M.2 connectors. It fits standard and low-profile chassis and requires no driver installation on any operating system. Builders who need to mix drive types on a single expansion card will find the layout convenient.

Low-profile bracket and mounting hardware included

The bundle supplies a half-height bracket, three M.2 screws, three standoffs, three nuts and a screwdriver so drives of different lengths can be secured without sourcing extra parts. A quick-start guide walks through the physical install. Systems without a spare PCIe x4 slot or with only M-key M.2 sockets cannot use this card.

One PCIe 3.0 x4 lane shared across three M.2 sockets

The single upstream link limits combined throughput to the PCIe 3.0 x4 ceiling, so simultaneous heavy traffic on the NVMe and both SATA drives will contend for bandwidth. Buyers who need full independent x4 links for multiple NVMe drives should look elsewhere.

Highlights

  • Add one NVMe and two SATA M.2 drives on a single PCIe x4 card
  • PCIe 3.0 x4 link gives full bandwidth to the NVMe slot
  • Driver-free installation works with any operating system
  • Low-profile bracket included for small-form-factor cases
  • Supplied screws, standoffs, nuts and screwdriver simplify mounting

Questions about this item

Will the B-key M.2 slots on the PEXM2SAT32N1 accept drives of different lengths without extra hardware?

Three mounting screws, three standoffs and three nuts are included so 2230, 2242, 2260 or 2280 modules can be secured in the card’s B-key receptacles.

Which interface limits throughput first when both SATA SSDs and the NVMe drive run heavy workloads?

The two SATA III ports top out at 6 Gbps each, while the single PCIe 3.0 x4 NVMe slot can reach roughly 32 Gbps, so the SATA links saturate first.

How much heat does the adapter add to a chassis during all-day operation?

The board draws power only from the PCIe x4 slot and has no active cooling; thermal load is limited to the SSDs themselves, which the card simply passes through.
