I currently have this PCB board (G3959A) on a 2TB hard drive that has been used in an external enclosure. I would like to add a PCB board that has SATA connectors so that I can add the drive to a NAS.

What PCB board would you recommend to get to replace the G3959A with that has the SATA connectors on it?

You can choose Toshiba PCB Board G3918A.

When you get this PCB, you need to move your original PCB’s BIOS to the replacement PCB. The 8pins (4 pins on each sides) with 25P05VP、25P10VP、25F512、25F1024、25F1024AN、SST25VF512、SST25VF010, etc. are the BIOS.
