RAID0 2 drives seems same speed as RAID5 4 drives, or am I imagining this?

I have two arrays, a RAID0 2 drive one I use for fast access and a RAID5 4 drive one I use for important files. I tend to keep everything on the RAID5 and copy stuff to RAID0 when I need faster performance.

Thing is I benchmarked both arrays and got around 200MB/s on both. Is this normal?

Great, its read I am interested in (for video editing).

I actually 2 2GB WD black and 2 2GB Hitachi. I am guessing mixing them is not advisable?
