RAID 1

Recently, I bought a 1TB HDD for upgrading my system and i still got a 320GB HDD,
Now I want to build a RAID 1 system
But the question is
1. Can i create a partition on 1Tb HDD same with the 320GB HDD and build the RAID?
2. The another partition's data can be kept if i build the raid.

I'd found for these information for many days but can't get a good answer.

  1. I think you can do that with Windows software raid. Not sure about hardware raid/motherboard raid (may depend on your controller) - but I would guess that you would lose the extra space. Maybe post up what motherboard / method you are considering.
  2. Honestly there would be no point. It is not impossible but that's about it.

    Many of the 320gb drives have a better access time than the 1tb drive, by a second one off ebay (ideally the exact same) and put it in RAID 0 and use the 1tb as backup/archive/storage. If you notice not increase in performance (such as boot up speed) go and put it in raid 1 for your important data.

    thanks for your reply.
    As i just have two hdd only
    so i want these two hdd increase the reading speed
    For me raid0 is very high risk and so i consider the raid1.
  5. If your are after a level of 'file security' provided by RAID 1 then you would be better of setting windows to back up (volume shadow copy) the 1tb drive to the 320, with the way windows compresses on backup you would probably fit more on than you might imagine.

    I just think RAIDing a drive mismatch like that is more hassle than its worth.
