The SanDisk Extreme SSD is designed for the outdoor enthusiast where performance, durability and a rugged aesthetic matter. The drive was created with a rigid ABS core with a silicone exterior. Not only does the silicone feel great it keeps water out and acts as a bumper passing an IPX55 water and dust resistance2 protection rating. The signature carabiner detail along with the discrete perforated pattern elevates a recognizable design language throughout the line of products.
