RAID fast hdd plus regular hdd?  should be easy question...

so... i am getting 2 western digital raptor harddrives... they spin at 10k rpm.... supposedly gonna be fast.... theproblem is... its only 74 gigs... not enough for my movie collection and photos... yeah... 50 gigs of images (i do photography)... so... i am wondering about my regular 160 gig harddrive i have now... regular 7.2k rpm... can i just add that as another drive on the SATA?  i plan to do striping with the RAID drives... so that will be one drive.  and then... can i just plug in another drive that is different on say... the regular SATA 2 connection? i mean... when your NOT doing RAID ... you can.  whatever speed you want... so... does this hold the same for RAID?  since the RAID drives will act as one... does that mean i can add whatever i want without hindering the performance of the RAID?  i plan to keep my photos and software on the RAID.. to make it run fast... and the movies and music on the other hdd... as that is not speed sensitive.

    If a RAID controller supports four drives, you could use two drives in a RAID array and one as a standalone (or two, or have another RAID array, there are many variations).  It should be noted that in the case of IDE there would be a performance hit on the channel that had the two drives connected.  In the case aof sATA, the channels are separate, so this should be ok.

    purple... so you are saying... 3 drives... 2 Raid striping and one regular drive... all connected on SATA connections... would probably not hinder the RAID performance?

    Yes, I am saying it won't hinder the RAID performance.

    IDE was designed with one channel supporting two drives.  The slower device would always hinder the other one on the same channel.

    sATA is one device per channel - so one drive won't adversely affect another.
