After releasing the rugged Armor A30 model, Silicon Power went ahead and upgraded it with a new Armor A60 model, which has passed the military drop-test standards (MIL-STD 810G), including the specific height free fall test of 122cm. Additionally, the product is water resistant by supporting the IPX4 standard while the internal Toshiba MQ01ABB200 drive is equipped with a G-force sensor for protecting itself when large vibrations are detected or when it falls off the surface.
