RAID noob with a couple questions

Greetings all,

I am looking in to setting up a server using Windows Home Server 11, and have some questions about RAID limitations. If I set up a RAID5 array (with say 3 1TB HDs), is it possible to add a 4th 1TB drive into the array without having to transfer all the data off the disks? Or is it possible to add in a 2TB drive either as a 4th or swap out one of the original 3 on the fly?

Also, when using a built-in RAID controller on a motherboard, what happens if the motherboard fails? Is the raid completely array lost?

Any help would be appreciated! Thanks.

Expand an array sounds simple enough... But it is not... It's the MOST intense data shuffle... It takes long time and very high rate of failure if you dont have a decent raid controller...

For WHS if you have to use WHS2011 then get a third party drive extender like: StableBit DrivePool, Drive Bender, SnapRAID, FlexRAID, disParity...

Otherwise use WHS V1 instead
With this controller S38-PCIe and SPM3726 (SiI3726 base) you can expand you data pool to 40x drives or 120TB with 3TB HDD.
