in my system i've installed a sata 3 SSD and a sata 2 HDD.
Can I put them on the same power cable, so I only need 1 cable? My sata powercables have 3 connections on 1 cable (after each other with some space between them). Or is it best to use different cables when you have spare cables and not use the free connections then?

the 1 connector is fine. if its got 3 connectors its fine to plug 3 sata devices (ROMS & HDD's) onto it.
All the drives are low power so they can share cable which improves cable management and airflow.
