SSD Raid 0 Questions

So here's what I would like to do.

I currently have a Crosshair IV Formula, with the AMD SB850 Controller.
I also have a single 60gb OCZ Agility drive. I would like to purchase another one, put them in a RAID configuration
that leaves me with 120GB of storage, with windows seeing a single drive. Then I want to install windows 7 on it as my boot disk.

I'm very good with pc hardware, just a complete noob at RAID. I've searched through a couple of forums, found little pieces of info, but am having trouble putting it all together.

So here's some questions I have.

1. Does trim pass through the sb850?
2. Is the raid config. I'd need RAID0?
3. What is drive alignment?
4. What should my sector size be?
5. Do I need to install a special driver during windows install to get the array to show up?
6. What could I do to reduce long term slowdown if I don't have trim?

Thanks in advance for all your help.

  1. Ask yourself this:
    1. Does your mobo support raid?
    If so, does it support trim in raid?
    2. If no to 1, do you have a raid card? IF so...
    3. Let us see your system specs. so that we may help you further.
  2. 1. Yes, SB850 is the chipset that the RAID would be functioning on.

    I've moved ahead on my raid, actually got the drives today.

    For other people who are looking for information, let me answer my questions.

    1. Does trim pass through the sb850?
    Nope, currently the TRIM command is not passed through a RAID controller.

    2. Is the raid config. I'd need RAID0?
    Yes

    3. What is drive alignment?
    An advanced format procedure that matches the windows sectors to the drive sectors. Vista SP1 & W7 should auto align.

    4. What should my sector size be?
    Here what I meant to ask is what should my stripe size be?
    64-128k, a lot of what I found said to just go with the default size

    5. Do I need to install a special driver during windows install to get the array to show up?
    Most likely not due to using W7

    6. What could I do to reduce long term slowdown if I don't have trim?
    The drives I am using are OCZ Agility. They have the indillinx controller which supports a firmware based garbage collection.
    When the drives go idle they do garbage collection which, is not TRIM, but helps keep the drive fast.
