2 sata to one slot

Can I connect to sata Hdd's with one cord? Because I only have 2 sata slots on my MB and I have 2 hdd's connected to each one, but i want to connect a sata DVD-RW and dont have a slot available

 

I have not heard of a splitter for the cables (but that does not mean they don't exist) another option is an expansion card but be warned they are not cheap (usually around $100)

Well that's the power of the internet, if you look around you can find everything.
The only ones i had seen were for multiple plugs and were expensive.
Nice find Just playin.
