I have no idea what your system is, but first I'll assume you have an Intel 6 or 7 series chipset board, with two SATA III ports, and usually four SATA II ports. Since your two Vertex 4's are likely on the SATA III ports, the next SSD you add would be on a SATA II port. That compromises the speed of the other two SSDs, since they must wait for the SSD on the SATA II port to respond. That will be most obvious in sequential read and write speed, which overall could be less then your two SSDs on SATA III in RAID 0.
Otherwise, on an AMD system (all SATA III usually) you'll see some increase in sequential speeds, and high queue depth benchmarks, but scaling drops off usually beyond two drives. Same for an all SATA II system. Will it perform better in actual use? Only way to tell is to try.
