SanDisk’s G-Drive ArmorATD is a portable 2.5-inch hard drive that’s ruggedized for less-than careful use. Though it commands a premium over non-ruggedized drives, it’s still reasonably priced for what it offers, and its performance is as good as you can expect from a 2.5-inch hard drive. Overall, the G-Drive ArmorATD gets our recommendation for economical, rugged portable storage.
