																																																The Ultimate SSDReach 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.
 
 PCIe 4.0 speed maximised
 Huge speed boost. 990 PRO offers sequential read/write speeds up to 7,450/6,900 MB/s reaching near the max performance of PCIe 4.0. 40% and 55% faster random read/write speeds than 980 PRO 2TB - up to 1,400K/1,550K IOPS, while 4TB has an even higher random read speed of up to 1,600K IOPS.
 
 Smart thermal solution
 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.
