That's about right. Some have reported success in getting this to run on RAID systems, but Microsoft recommends against it. If you were to set up WHS on a RAID 5 system, for example, you would need to turn off folder duplication, as the array would look like one (giant) disk to the OS. However, there is really no reason to do this as folder duplication accomplishes redundancy via mirroring.After looking briefly, it doesn't seem like it supports the raid 5... or does it?
It only supports the folder duplication....
Is that about right?
If this is correct, it also means that it doesn't support raid expansion and etc, right?
Hope I am wrong as this is the primary reason why I am considering this particular NAS.
Expansion IS supported however. If adding a disk, you simply tell WHS to add it to the storage pool, and the additional space is added and managed completely transparently. If you wish to replace a disk with a larger one, you must first remove it from the storage pool (WHS will automatically copy all files on that disk to other disks in the pool), and then physically change out the hard disk and then add the new disk back to the pool.
