SFF-8643 to U.2 M.2 adapter for 2.5-inch bays

This adapter kit lets you install an M.2 solid-state drive into a 2.5-inch drive bay using either an SFF-8643 Mini SAS HD connector or a standard SATA 22-pin interface. It accepts M.2 modules in 2230, 2242, 2260, 2280 and 22110 lengths with B-key or B+M-key pinouts. The copper construction carries PCIe 3.0 x4 signals for NVMe drives or SATA signals for SATA drives. It is designed for desktop and laptop systems that have a compatible backplane or controller card.

Replaces direct M.2 slot or 2.5-inch drive caddy

The kit upgrades a system that lacks a free M.2 socket but provides an SFF-8643 port or a SATA 22-pin header, letting you reuse an existing M.2 SSD instead of buying a native 2.5-inch drive. The jump is worth it when your motherboard or RAID card exposes an SFF-8643 connector wired for PCIe 3.0 x4 and you want NVMe speeds, or when only a SATA port is available and a SATA M.2 drive is on hand. It does not work with SAS drives or controllers that expect SAS signalling.

Check your controller

Verify that the SFF-8643 port on your mainboard or add-in card is wired for PCIe and not for SAS, because the adapter will not function with SAS signalling. Confirm your M.2 SSD uses a B-key or B+M-key edge connector; M-key-only NVMe modules will not fit. Ensure the drive length matches one of the supported form factors from 2230 to 22110. No additional power connector is described, so the drive must draw all power through the adapter.
