Will this be a problem ? i know that The SLOWER of the drives… will dictate the overall speed, other than that, is there any real problem to use different hard disks Models with the same capacity? please advice

Answer:WD Green?
Not in any RAID, ever.

Their claim to fame is to spin down when not needed. The delay in spin up may corrupt the array.

Never ever.
