The Stream S07 was carefully designed after a stone, a symbol of durability and longevity. And just like a stone that's been tested through time, it has a crack. But this crack is intentional – it has a dual purpose. First, it serves as a ventilation source to keep the drive running cool. Second, with built-in neon blue LED lights, it serves as a transfer status indicator that runs through the crack, illuminating it while processing data.
