adding another ssd and want raid 0 maybe?

I have a 128 gb ssd with my os on it and when I got it didn't really think I would use that much but im at 59 GB free space, so I was thinking of buying a 256 GB ssd and putting them into raid giving me a 384 GB ssd. Now I don't know if I should put them into raid 0 or 1? do have a 1 TB hard drive for backup and other files which also hold some of my games because I was running out of space and im getting confused on which drive I put them on so I figured another ssd would help. any thoughts would be appreciated thanks

  1. Raid 0 gives you more performance, but 0 reliability.

    Raid 1 lowers the storage/performance, but gives you reliability in the event of a drive crash.

    Take your pick.

    Doesnt work like that, you need identical drives otherwise you will run into capacity/performance limitations.

    This tutorial will explain how it works.

    For SSD's there is no real need to run a RAID0 array, their main advantage is fast access times, which doenst improve in a RAID enviroment.

    The total capacity of a RAID-0 array is based upon the drive in the array with the smallest capacity.
    So if you RAID-0 a 128GB drive and a 256GB drive then your RAID array’s total capacity (before formatting) will be 256GB (128 x 2).

    The total capacity of a RAID-1 array is also based upon the size of the drive in the array with the smallest capacity.
    So if you RAID-1 a 128GB drive and a 256GB drive then your RAID array’s total capacity (before formatting) will be 128GB.
  4. Don't RAID them at all. Keep them as separate drives. If you are short on OS space, you could
    1) Set the installation directory on all future installs to the second SSD and have your programs on both.
    2) Clone the 128 GB drive to the 256 GB drive and use the 256 GB drive as your system disk. I prefer this answer.
    3) Do something more complicated.

    BTW, have you moved My Documents off the OS SSD, or are you storing all of your data on that drive? Moving your data to an HDD might free up enough space.
