So i have a M4 Crucial SSD 128gb i'm planning on buying another 128gb, for raid 0
My question is when i put these 2 on raid 0, will i only have 128gb on raid 0 or 256gb ?

Also am i able to raid a m4 crucial 128gb with a samsung pro 128gb?
 
Raid 0 "mirrors" the other drive so you don't gain space and it just duplicates. It is recommended or preferred to have the same drive units as there is less chance of problems. You are only as fast as your weakest link. Check the specs for the raid controller for requirements.

Why would you raid 0? When a stripped set would give you better performance. Do you need redundancy and are you that concerned about failure?
 
No i'm not concerned about failures. XD
Don't really need more speed just wanted some extra space.
I was watching a vid from Linus, & apparently you get to keep all the capacity in raid 0?

Extra space for having bf3/bf4/windows 7/8 in the ssd, & i can't do that in 1 128gb XD.

& when you say "Duplicates it" So i'll have 256gb?.....
