Whatsup ROG Forum!

I am a proud new owner of a G551JM-DM118H, The configuration is as follows,

CPU:Intel Shark Bay Core i7-4710HQ
RAM:8GB (2x 4GB) 1.35v DDR3L-1600 (4 Slots Upto 16GB)
GPU: Nvidia GTX860m
Storage: 1TB 7200rpm HDD (Support 2x 2.5" with RAID 0)

My Question is that mine did not come with an SSD, But i want to put one in, only issue is where and what format?
Do i get a 2.5" SSD and add it on? If so where as there is no additional slot that i can find in the user upgrade area,(do i have to replace the CD/DVD ROM?

Or do i buy an SSD in mSATA format and place it into the mSATA slot, If so is there any requirement or limitations?

Is there anyway i can Add an SSD without replacing anything?

Thanks guys,s
