Basically for RAID Support on Motherboards Only RAID 0 and 1 are supported.
RAID 0 - Striping provides no added data protection,
the speed of storage is increased because
the system will treat multiple, (usually only 2),
hard drives as a single drive.
Once the drives are striped together though,
they cannot be placed on a conventional IDE
controller, nor can they be separated. Data
has been spread across these drives and they
are a combined unit. There may be cases
where a controller that had been used to stripe
a drive set may not be compatible with another
controller.
Usually on motherboard RAID controllers if you
have only one drive, you configure the system for
striping with only one drive assigned to the
Array. ("Array" being a term used by RAID
controllers. An "Array" is basically, what the
hardware will see as a single drive, and
the controller allows you to organize what
drives will be in the array, and how they will
be used.)
RAID 1 - Is Mirroring. Where one drive contains the
identical data in another drive. If one a
single drive fails you still have your data,
and the system still runs.
Read times are often improved because most
controllers will enable reading to be distributed
between drives. Sometimes write times will be
increased, but it's not normally the case anymore.
Most motherboard controllers really only handle RAID 0 and RAID 1, so those are probably you only choices.
Simply put RAID 0 is for speed, and RAID 1 is more for data protection.
I, personally, happen to be "VERY fond" of the Raptor drives. They tend to be a bit heavier than standard drives, they produce a bit more heat but not that much, they are pretty quiet although I know some people that have complained about higher pitched sounds from them, and their performance is quiet pleasing.
Also SATA should have an advantage or IDE since each drive, at least in theory, could be accessed simultaneously. (it seems to work on the Promise S150 TX4 cards, but that's all I've played with extensively.)
I also think this is still true!
Windows 2000, (this is true), and Windows XP, (I think this is true), DO NOT recognize most RAID controllers natively. So when you install "fresh" to a drive on a RAID controller, you will need to press the "F6" key and install additional hard drive controller drives. (I think it may actually say "third party", but I don't remember.) If you don't do this, and Windows doesn't install a compatible driver, what will happen is your boot process will begin and when Windows is starting it will blue screen and say it can't access the drive.
If you have an existing install, you can just add the driver when the drive is on a non-RAID controller, and then either move the drive to a RAID controller or Copy the disk image to a RAID Array. (Depending on the controller, and how the Array is defined.)
This is must longer than I thought it would be sorry, but there is one last thing!
I know that there is a version of the A7N8X motherboard that has SATA on board, and that has RAID on board. What I am not sure about is, whether the SATA is just a standard SATA controller, or both a RAID SATA controller?
I am like 95% sure that there are standard SATA ports of that motherboard, but I have no knowledge as to whether there are RAID SATA ports on that motherboard?
But you're only getting one drive, so that doesn't matter at this moement! : )
I hope that helps,
Jim
