Vszerda M.2 Key B+M to Dual SATA 6.0Gbps Adapter

This new adapter converts a single M.2 NGFF Key B+M slot into two vertical SATA 3.0 ports. It uses a JMB582 controller to deliver 6.0Gbps, 3.0Gbps and 1.5Gbps transfer rates. The card supports hot swap, hot plug and power management functions. It is built for Windows, macOS and Linux systems.

Suits builders adding two SATA SSDs to an M.2 slot

Ideal for users who have a free M.2 Key B+M interface and want to run a pair of SATA solid-state drives as system or data volumes. Native command queue support helps maintain performance and stability under heavy workloads. Not suited for buyers who need more than two SATA connections from a single slot. Not suited for systems that lack an M.2 Key B+M connector.

JMB582 controller with dual SATA 3.0 6.0Gbps ports

The JMB582 main control chip provides two SATA 3.0 interfaces with error reporting, recovery and correction. It supports Gen1i, Gen1x, Gen2i, Gen2m, Gen2x and Gen3i signalling plus partial and sleep power states. Copper conductors ensure reliable signal integrity. This specification determines whether the adapter matches the host slot and drive requirements.

Questions about this item

Does my motherboard need an M.2 Key B+M slot to use this adapter?

Yes, the adapter plugs into an NGFF Key B+M PCI Express slot on the motherboard.

Will my older SATA 3.0 Gbps and 1.5 Gbps drives work with the JMB582 controller?

The JMB582 supports 6.0 Gbps, 3.0 Gbps and 1.5 Gbps SATA speeds, so legacy drives will operate at their rated rate.

How can I verify the adapter is functioning after I install it?

The drives should appear in the OS device list and SMART data should report Gen1i, Gen2i or Gen3i link speeds with NCQ active.
