I don't think there's much advantage of using a large capacity harddrive like that. Personally, I rather use 6-500G. or 3-1T instead (especially if the price comparison is about the same or not too much higher).
It appears the 3Tb HD is here. WD, is offering it as a "bootable" one that being the major point. You need to have these requirements in order to use it.
1) 64-bit OS
2) UEFI and GPT partitioning
If you system needs it, WD will provide a small PCB card in order to better i/f the HD for compatibility.
The 64-bit OS is very important as it addresses the capacity or volume issue, as 2.19Tb is the limit for 32-bit OS, thus the 64-bit OS need.
There are other 3Tb out there but it seems the WD offered one is bootable, other will be storage only.
