    What laptop do you have?
    Only a few laptops support Raid 0.

    By the way, if you do not own a D900K, than you have a software based RAID controller, meaning that the performance gain by putting the drives into RAID 0 is less than a 5-7% gain.

    Raid 0 is not worth it in most cases. Setting the drives into raid 1 is a good idea, but if you just want all the capacity leave the drives in spanning mode like they are now.

    Raid 0 means that both harddrives are used simultaneously to open something.
    basically, say you have a file which is 2mb. 1mb of that file will be stored on one harddrive, and the other 1mb will be stored on the other harddrive.
    When you go to open that file, both drives open the file simultaneously, resulting in faster load times.
    However almost every laptop has a software raid controller, so the loading is not really simultaneous, their are lag issues because their is not a physical chip doing the sorting and loading work, it is software.
    The benefit of Raid 0 is like 5-7% faster loading times, and
    if you have two 500gb drives, the total capacity is 1000Gb
    The downfall of Raid 0 is that, if one drive dies all of the files on both harddrives are lost.


    Raid 1 works differently. Say you still have the same 2mb file. On the first harddrive their is the 2Mb file, and on the other harddrive their is also the same 2mb file.
    Raid 1 can be easily understood as a mirror. Everything on the first harddrive is also on the second harddrive.
    The benefit to raid 1 is that if one harddrive fails, you do not loose anything
    the downfall of raid 1 is that if you have 2 500gb harddrives in your laptop the total size is 500gb.

    Just to add on to this, the other downfall of Raid 1 (as a backup solution) is that it is really ONLY significant for HDD failures. If you delete a file on one drive you delete it on the other or if a virus affects one drive...it's affecting both. So, in my opinion, Raid 1 is pretty worthless...

    RAID1 is still useful for failed drives. Viruses isnt a worry compared to a failed drive. You can still recover stuff from an infected drive.

    Personally id go with RAID 0 while running backup exec to do daily/weekly incremental backups to a external device.
