Raid question

Raid Questions.

I have 160x 2 in Raid Configuration.

Not sure if it's raid 1 or raid 0. It's mirroring.

If I get a 250gb HD.

Would I be able to get all the data off 160 and have 250gb total storage ?
or would it just partition to 160gb ?

If your drive is mirroring, then is is setup for Raid 1. If you setup your drives for Raid 0 instead, then you would have 320gb... but the fact that you have your drives in Raid 0 in the first place tells me that you are concerned about fault tolerance. There is no fault tolerance with Raid 0 (in fact it is much worse).

Are you using SATA, SCSI, or PATA?

It came with Raid 1 from the factory.
it's SATA

i wanna get larger drives than 160gb possible 250gb - 300gb

Do you still want to use Raid 1 with your new drives?

What brand are your drives?

Currently
my 160gb's are Western Digitals.

Western Digital gives you hard drive tools that will copy all of your information from one drive to another.

(recommended technique) As long as you have the power requirements and extra ports to support 4 SATA devices, you could create a new Raid 1 array with your new drives and use the WD tool to backup from one raid set to the other.

Another technique (not recommended), install only one 160gb and one 300gb. Backup from the 160 to the 300, then remove your 160, install your second 300gb and install a software RAID 1 over the two 300gb disks (Windows XP Pro / Windows 2000 Pro can do this).

There are a few other methods, but i'm still wondering... Why are you are using RAID 1? Most people would like to have 600gb of useable space as opposed to a 300gb RAID 1 mirrored set.

I don't want to run a Raid 1.
It was defaulted

I want the extra space

So the only good way is to start another Raid 1 array and copy it from the WD?

If you do not want another RAID 1 array, then you just need to install a new hard drive and use the WD tool to copy all of the information from the RAID 1 array to the single HD.

You could also remove RAID 1 from your existing hard drives to make two seperate 160gb drives (320gb total useable space).
