PCIe to M.2 SATA adapter with M and B keys

This adapter connects a SATA M.2 SSD to a free PCI Express slot. It accepts both M-key and B-key modules so one card covers the common SATA form factors. The board adds storage without occupying a 2.5-inch bay or a motherboard M.2 socket. Builders upgrading older platforms or filling spare PCIe lanes can use it to add solid-state capacity.

SATA-only design limits use to SATA M.2 drives

The card passes only SATA signals, so NVMe M.2 SSDs will not function even if they fit the slot. It also provides no RAID or boot management beyond what the host BIOS offers. Buyers needing NVMe speeds or multiple drives from a single slot should look for a different controller.

Yes, the card accepts both M-key and B-key M.2 SATA drives and connects them through a PCIe interface.

How can I confirm the adapter is working after I install it?
