EX4100: RAID with only two HDDs possible?

I currently use a Buffalo NAS, with which I am, however, very unhappy!

Now I want to buy the WD EX4100, but initially continue to use only the old two hard drives in a RAID and later, if necessary, use the extension option for two more drives.

So, can the EX4100 be used with only two HDDs in a RAID?

Thanks for your efforts!
