SMUGDESK P571 PCIe 5.0 Adapter 12+16 Pin to M.2 M-Key

Mac SSD reuse adapter

The SMUGDESK P571 adapter converts proprietary 12+16 Pin SSDs from 20132017 MacBook Air and Pro models into a standard M.2 M-Key NVMe interface. It plugs into desktop PCIe x4, x8 or x16 slots and operates over a PCIe 5.0 x4 link with 20Gbps bandwidth, backward compatible with PCIe 3.0 and 4.0. The compact purple PCB measures 131x50mm with gold-plated contacts for reliable signal transmission. No drivers are required and it works with Windows, macOS and Linux.

For DIY upgrades of Apple SSDs

This card suits enthusiasts and IT professionals who want to repurpose retired MacBook SSDs as high-speed desktop storage. It supports NVMe and AHCI protocols on Mac models A1398, A1465, A1466 and A1502. Builders needing to connect standard M.2 drives or other proprietary connectors should look elsewhere because this adapter only accepts the Apple 12+16 Pin format. Users without an available PCIe slot cannot install it.

PCIe 5.0 x4 interface at 20Gbps

The single specification that decides fit is the PCIe 5.0 x4 host interface delivering up to 20Gbps bandwidth. Your motherboard must provide a PCIe x4, x8 or x16 slot; the adapter will negotiate down to PCIe 3.0 or 4.0 speeds if the platform is older. Without a compatible PCIe slot the card cannot function, regardless of the SSD you intend to use.
