NGFF Key B+M 5-Port SATA Adapter

The Vszerda adapter converts a single NGFF Key B+M slot into five SATA 3.0 ports using the JMB575 controller. It targets builders who need to attach multiple 2.5-inch drives to a compact board or mini-PC that only offers an M.2 socket. The compact black PCB weighs 11 grams and fits a 2280-length slot.

Check M-Key Slot and Port Multiplier Support

Verify that your motherboard or laptop provides an M.2 slot wired for Key B+M SATA signalling, not PCIe only. The host must also support SATA Port Multiplier revision 1.2 or Port Select revision 1.0 so all five drives appear to the operating system. Without that support only the first drive may be visible.

JMB575 Controller with Cascaded Ports

The JMB575 integrates five independent SATA 6 Gbps channels and a microprocessor on one chip, enabling cascaded operation for up to five drives. It complies with Port Multiplier 1.2 and Port Select 1.0, plus BIST and loopback diagnostics. Five standard SATA data connectors face upward for straightforward cable routing in tight chassis.
