Expand Raid Level 0+1

Hi,

i have a raid 0+1 with 2 harddisks.
Now i bought another 2 harddisks with the same size. i want to expand the logical drive to have more resources. what i have to do ???
must i delete the mirror first ???

when i use the express wizard in acu to expand the array they will create a new logical drive but i dont want a new one. Or should i use the configuration wizard to expand the array ? when i use the configuration wizard they appears an dialog wheere i can add two disks to the existing array and they show me a container with free space below the logical drive.. is this the right step ??

Thanx for help..

Rene

Yes it is .. once you see that free space click the existing logical drive and then choose extend.

Take a read through this for limitation on extending logical drives that are in Windows

Technically speaking i think the 0+1 would be faster since your reading the data from 4 drives at once compared to reading the data from 3 drives.
