NGFF dualSSD riser card Compatibility and interfaces Suitable for NGFF (M.2) form factor with Bkey or B/Mkey interfaces. Not compatible with Mkey interfaces. Requires drives that support AHCI and NVMe protocols; drives not supporting these protocols are not supported. Dual slot with singleactive operation Two SSDs can be installed at the same time. Only one SSD is recognized at a time; use the switch to select the active drive. The switch must be toggled to the corresponding position to activate the chosen SSD. Practical benefits Enables efficient use of space by supporting two drives on a single riser. Simple manual switching allows quick access to either SSD without removing drives. Helps with testing, data migration, or smallformfactor setups where one active drive at a time is sufficient. Use scenarios Hardware testing or development bench: install two drives and switch between them to compare performance or test configurations without swapping cables. Data migration or backup workflow: keep both drives connected, switch to the source or destination drive as needed for cloning, imaging, or backup tasks. Compact workstation or server minisetup: expand storage options in a tight build while maintaining clear control over which drive is in use.
