Storage accessory maker G-Technology has expanded its line of external storage devices today at CES with three new ruggedized drives and a new protective case. The new hard drives are outfitted with shock-proof cases to survive drops onto hard surfaces or into water. Prices range from $80–$230, depending on model and storage capacity, and offers options for either USB 3 or Thunderbolt connectivity. In addition, the company is selling its latest protective case separately, so that users can "ruggedize" existing G-Tech drives.
