8 Port SATA III 6Gbps to M.2 B+M Key PCIe 3.0 x2 Adapter Card, Non-RAID SATA Expansion Board for M.2 B/M Slot Storage Extension

This M. 2 B+M Key SATA expansion adapter turns a spare M. 2 slot into 8 independent SATA III ports with pure non-RAID architecture, perfect for users needing multiple storage drives without RAID functions. Built on PCIe 3.0 x2 bus, the card delivers sufficient bandwidth to support simultaneous operation of multiple SATA devices, each port maintains native 6Gbps maximum transfer speed without speed compression. It only works with M. 2 B Key or B+M Key slots and fits standard 2280 M. 2 mounting positions on motherboards. All SATA connectors adopt gold-plated contacts to resist oxidation and lower electromagnetic interference, guaranteeing reliable long-term running for mechanical hard drives, solid-state drives and SATA optical drives.

The compact PCBA layout saves internal chassis space without bulky PCI bracket design. No RAID chip onboard, each connected disk is independently recognized by the system. Automatic driver matching under Windows and Linux systems, no extra software installation needed. Great for DIY multi-disk storage workstations, file storage servers, video editing equipment and desktop storage capacity expansion.
