M.2 SATA to 2.5" SATA adapter with USB 3.0 cable

This PCB converter adapts an M.2 NGFF B-key or B+M-key SATA SSD into a standard 2.5-inch SATA form factor. The bundle includes a SATA-to-USB 3.0 cable so the drive can be used as portable external storage. It is designed for users who want to repurpose a spare M.2 SATA module without an internal drive bay.

USB 3.0 bandwidth limits real-world transfer speed

The adapter passes the SATA signal through a USB 3.0 connection rated at 5 Gbps, which caps the maximum throughput below the native SATA III ceiling. Performance will fall back to USB 2.0 speeds when connected to older hosts. No driver is required for Windows, macOS or Linux, but the USB link remains the bottleneck for sustained reads and writes.

Only SATA-protocol M.2 SSDs are supported

The board cannot recognise or operate NVMe PCIe M.2 modules, so the SSD must use the SATA protocol. Buyers with NVMe drives need a different adapter. Verify the drive specification before purchase to avoid incompatibility.

Questions about this item

Which M.2 SSD key type works with this adapter?

The adapter accepts M.2 NGFF B-Key and B+M-Key SSDs that use the SATA protocol. NVMe PCIe M.2 SSDs are not supported.

What transfer speed does the USB 3.0 cable provide in practice?

The USB 3.0 cable delivers up to 5 Gbps bandwidth, giving fast file-copy speeds for the SATA SSD, and falls back to USB 2.0 on older ports.

Does the SATA interface limit the drive’s performance over USB 3.0?

The SATA SSD connects through the adapter’s native SATA traces, so the USB 3.0 link runs at full 5 Gbps without a SATA bottleneck for everyday file access and backup.
