Adding More Storage With A RAID 1 Array
I have a Dell 8400 which has a RAID 1 array composed of two, 160GB hard drives. My system board shows 1 IDE controller {which has my DVD player and DVD burner connected} and 4 SATA controllers. I have searched through my Dell documentation and found litte info. Pasted below is my "Intel Storage Utility" report.
How might I add more space?
Thanks,
Jeff Farrar

Hi Farrar,
IMHO there are two ways that you can extend the RAID's capacity:
1 - the easy (short) and bad way - you can simply attach additional SATA or IDE drive to the computer and extend the volume to it (using disk administrator - create a dynamic disks which its data spans more than one storage device). This is bad - it works slowe and you loose the Redundancy factor.
2 - the hard (long) and good way - purchase larger SATA disks (I see your raid is constructed from two identical Seagate SATA disks). Image the data on the raid container to an external hard drive (i recommend on ghost). replace the disks inside the computer (with the two disks you purchased). Restore image to the newly created container.
P.s. I know that you can image the data "directly" from one raid to another but this is a more "risky" way. better take the longer and safer path.
P.s. #2 Raid 01 is usually slower on write and faster on read than a standalone drive.
Good Luck,
Gabriel
