Specs: Windows 7

i bought a new HDD toady, and i have a HDD already installed in my computer.
the new HDD is 1.5T and the old one is 500G. both SATA 2.

i would like windows 7 Ultimate recognize them as 1 HDD.

My motherboard is MSI Platinum P45.

i know i need to configure them as RAID 0.
but when reading on how to do it, i saw that everyone who asked about it has some kind of a controller.
is there any way to configure those HDD as raid with no controller?

thanks a lot for helping

You information is not fully correct.

RAID 0 is one way to accomplish that (not recommended) but you can also configure the hard drives as a dynamic disk, which will assign only one drive letter for all the storage space included in the disk/array.

Unless you have a compelling reason to do this, like the path to the data has to have just that one drive letter, then I would recommend against it. When creating a dynamic disk/array you place ALL the data at risk, should any part of the hardware fail. If you do this you should also have a good backup plan in place.

Why do you want to do that anyway?

You do realize you can still use the second drive by just adding it in?

You don't need a controller but it is better. You can format your new drive into 3 partitions of 500GB. Then you can setup raid by going into the Disk manager of Windows.

P.S. I don't recommend you do this because if your Windows Fails or one of the drives fails then you will lose stuff on both drives. RAID 5 is much better than RAID 0 because it is fault tolerant.

You best results will come from buying 4 drives of the same configuration and a SATA RAID Controller. Then you can setup RAID 5 or better yet RAID 1+0. Any thing else is a waist and is dangerous unless you are doing this as a hobby.

True but you can't do that without a controller so I was giving him the second best thing.

Besides RAID 0 is old school and is hardly ever used because it is not fault tolerant. And to set it up on different drives with different speeds and sizes is not wise. As you can see in my P.S. to the OP.

Besides your post was not there when I was writing mine so sorry if I stepped on your toes.

You don't need a controller to use dynamic disks. May need to ugrade the version of Windows 7, not sure about that.

Read the link I provided above. I guess we need to know what the OP is trying to do.

thanks a lot for your help.

OtheHill, i want to do it because i use my 2 HDD for storage, and my 500G HDD is full, and i dont want to start open same folders on the new HDD, and then wont remember where i saved what.

ACE: y i need to format my new HD with 3 partitions? what will comeout of it? do u mean to format it with 3 partitions for RAID 5? for the parrity? dont i need 3 physical HD for that?

i dont wanna buy 4 HD, for it will make this solution too expensive for me.

so, what u saying is, if ill configure my HDD as RAID, when 1 of the HDD will stop working, i will lose all data?
it is the same for Dynamic disks?

OtheHill : thanks for your link, i will read it later

Install the hard drive into the computer and then boot into Windows 7.

Then follow the Microsoft instructions on how to create a dynamic volume in the link I provided.

You DO NOT need to make three partitions on the new drive.
