    The X18's use a MicroSATA connector for power instead of the standard SATA, as they need power from the 3.3v rail instead of the 5v. I bought one in a pack that already had a power converter mounted on the PCB, and then other one I bought I had to buy an adapter to connect the power.
  2. The X18-M are based on the G1 controller i think, while X25-M you get the G2 controller. Not sure tho.
  3. x18's are also G2.
  4. Thanks alot. Seems spot on with the 3.3V vs 5V power requirement.
