Reach max performance of PCIe 4.0. Experience longer-lasting, opponent-blasting speed. The in-house controller's smart heat control delivers supreme power efficiency while maintaining ferocious speed and performance, to always keep you at the top of your game. Huge speed boost. 40% and 55% faster random read/write speeds than 980 PRO - up to 1400K/1650K IOPS, while sequential read/write speeds up to 7450/6900 MB/s reach near max performance of PCIe 4.0. Fly high in gaming, video and 3D editing, data analysis, and more. More power-efficient performance. Higher performance usually consumes more power. But, 990 PRO uses less power with over 50% improved performance per Watt over 980 PRO. This low-power design makes max PCIe 4.0 performance possible with optimal power efficiency. Speed beyond the heat. The nickel-coated controller and cutting-edge thermal control algorithm manage heat for unwavering performance. The heat spreader label controls NAND chip heat, while Dynamic Thermal Guard keeps temperatures optimal. The best gameplay experience. A more than 55% improvement in random performance enables faster loads for ultimate gaming realism on PS5 and DirectStorage PC games.
