Hello,
Currently I have old (slower) HDD and a new (faster) HDD what will happen If I made a striped partition from those two, Do I still benefit the RAID 0 performance?
 
I would probably not even think about trying this, if indeed it is possible at all. Most RAID controllers are very finicky about what drives they will band together, so that difference in speed might be enough to shoot the whole thing down. Assuming that it is possible to create the array though, you should in theory get a good amount of speed benefit, less than if both drives were fast but still there.

I don't know why you would really want to do this though. There aren't a great many applications where you need the space of HDDs with the speed of RAID0 anymore. What are you trying to do with this system?
 
No . you don't need to RAID 0 because there is a big difference between SSD and HDD . just enable AHCI . you will more performance on SSD and little more performance on HDD if you enable AHCI mode . AHCI will enable Turbo write for SSD and NCQ for HDD . RAID will also enable what AHCI enables . the problem is RAID 0 is merging slower HDD and much faster SSD . what Lostalone said is also right.
 
I don't use SSD in the configuration, I only want some speed with the current HDDs I have.
As most of today's games are 30 GB+ and my SSD is only 120 so I have to install some games on my HDD that's why I was considering this setup. since windows 8.1 build in disk management provide an easy way to create a striped partition from the two disks
Thought it would be a good idea if I took 200 GB from each HDD and created a 400 GB faster partition
 


Supremely bad idea. As said above, the slower drive will hamper the faster, possibly to the point of not working.
