The WD Sentinel server comes with either one (DS5100) or two (DS6100) 2.5-inch boot 
drive pre-loaded with Windows Server 2012 R2 Essentials and specialized hardware 
services and drivers. The pre-loaded boot drive(s) provides the ability to keep the OS 
running from the boot drive while redeploying or changing applications and folders running 
on the large capacity data drives.
