The DS215j is powered by a dual-core processor with Floating-Point Unit (FPU) that unlocks its power in multitasking and multimedia processing. The platform upgrade enables the DS215j to deliver average read speeds over 111 MB/sec and average writes over 87 MB/sec, a 19% gain in writing compared with its predecessor, while keeping its power consumption as low as 13.4 watts in full operation and 5.3 watts when hard drives hibernate. The addition of the SuperSpeed USB 3.0 interface further boosts its file transfer speeds.
