On my SATA hard drive i noticed two power connectors. There is a 4 pin molex and a sata power connector. Why is there two of them and which one is better to use? Is it the exact same thing?

The two power connectors are provided for versatility - not all power supplies have a SATA power plug, so a spare Molex plug can be used instead. Molex plugs are typically very firm and unlikely to fall out, but a SATA power plug is designed to unplug easily, as SATA drives are hot-swappable. Consequently, if a system has a Molex plug free, it's probably best to use that, so the plug is less likely to work loose & fall off if the system is transported.
