    I have two 750GB internal drives in addition to the 320GB boot drive that holds my system.

    The 750s are going to hold my user directories. If I use software RAID 1 (I don't have the card) will it slow things down substantially? For the time being, I have no scratch disk, and most of my media and work will occur on these disks.

    Any other ideas?

    It should not slow down your computer. RAID 1 is not a complex thing, and your computer is fast enough that the RAID calculation overhead should be close to nothing.

    You should see a performance increase. Reading from a RAID 1 array gives you a speed increase because your computer reads from both drives at the same time.

    The only downside is that you lose half of your storage space.

    No, it won't slow things down perceptibly. Even on my old G4-400 Server, my two RAID 1 arrays work well and don't affect performance.
