Product Use: Converts the SATA signal of an M.2 NGFF drive to a SATA 7-pin connector, allowing connection to a 2.5-inch hard drive or SSD to increase storage capacity. The M.2 to SATA 3.0 adapter card converts an M.2 NGFF interface to a SATA interface. The board has four mounting holes: 22*42mm, 22*60mm, and 22*80mm. Cut the hole to fit the slot in your machine. Make sure it works before cutting; returns are not supported after cutting. Warm reminder: This adapter card only connects to SATA protocol M.2 interfaces (KEY-B interface). PCI-E or NVMe protocols are not compatible. Please confirm your interface is SATA before purchasing. This product does not support 3.5-inch hard drives or optical drives, it need an external power supply.
