If you haven't experienced a hard drive failure in your lifetime, let's just say - in the eloquent worlds of our IT team - you will. And because file storage comes so cheaply these days, there's really no excuse to not invest in some kind of backup solution for your precious digital irreplaceables...

Perhaps WD's new My Book World Edition II NAS (network-attached storage) offerings may be right down your alley. Packing up to 4TB of mirrored RAID 1 space (2TB usable), you'll finally be able to continue trucking along paranoia-free, or until one of your drives decides to take a dive - whatever comes first.
