Green circuit board with two M.2 slots and metal bracket

SMUGDESK

SMUGDESK PCIe 5.0/4.0 Dual Bay M.2 NVMe SATA Adapter P582

SKU CH-002D-S1Z2Q

Adds two M.2 slots for NVMe and SATA SSDs via PCIe 5.0/4.0 with gold-plated PCB, P582 chip, metal bracket and SATA cable

  • Supports two M.2 drives at once for doubled storage capacity
  • Gold-plated PCB delivers ultra-stable high-speed signal transmission with anti-interference
  • P582 controller chip ensures reliable performance under continuous heavy loads
  • Sturdy metal bracket plus SATA cable simplify installation and power delivery
  • Fits standard PCIe X4, X8 and X16 slots for desktop, workstation and NAS expansion

Dual-Bay M.2 NVMe & SATA Expansion

This adapter card adds two M.2 slots to a desktop, workstation or NAS through a standard PCIe x4, x8 or x16 slot. It accepts both NVMe and SATA protocol SSDs simultaneously, using the P582 controller to manage data flow across the dual-bay layout.

Simple Slot-In Installation

The card seats directly into any compatible PCIe slot and secures with the included metal bracket. A matching SATA power cable connects the onboard SATA power pins to the system supply, so both drives receive power without extra adapters. Gold-plated PCB traces help maintain signal integrity during heavy workloads.

Verify Slot And Drive Compatibility

Confirm the motherboard provides a free PCIe x4, x8 or x16 slot that can bifurcate or route enough lanes for two M.2 devices. Check each SSD is either an NVMe or SATA M.2 module, as other protocols are not supported. Ensure the case has clearance for the full-height bracket and the SATA power cable routing.

Questions about this item

How do I verify the P582 chip is running at PCIe 5.0 speed after installing two NVMe drives?

The board uses a P582 control chip rated for PCIe 5.0/4.0; confirm link speed in your motherboard BIOS or an OS tool such as Device Manager to see each drive negotiating at Gen 5.0 x4 or Gen 4.0 x4 depending on your platform.

What comes in the package and which items must I supply myself?

The package includes the dual-bay adapter card with gold-plated PCB, a metal mounting bracket, and a SATA power cable; you must provide up to two M.2 NVMe or SATA SSDs and an available PCIe x4/x8/x16 slot.

Should I choose this P582 model or a different adapter if I only need one NVMe drive?

This P582 card is built for two drives at once — NVMe or SATA — so if you only need a single NVMe slot a single-slot adapter would be simpler and leave the second bay unused.
