From the manufacturer

Cool performance for heated action


Get almost all the performance that the currently fastest standard PCIe 4.0 offers.¹

Rapid speed and high energy efficiency


PCIe 4.0 speed maximized

40% and 55% faster random read/write speeds than 980 PRO – up to 1400K/1550K 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.² ³ ⁴


Breakthrough power efficiency

The 990 PRO uses less power with up to 50% improved performance per Watt over 980 PRO. This low-power design makes max PCIe 4.0 performance possible with optimal power efficiency.⁵


Smart thermal solution

The slim heatsink dissipates heat to prevent performance drops from overheating. Get stable heat control, and minimal fan noise for heavy-graphic gaming. The thin body is compatible with PlayStation 5, desktops, and laptops meeting the PCI-SIG D8 standard.⁶

Gaming the way it should be


The optimal gameplay experience

A more than 55% improvement in random performance enables faster loads for ultimate gaming realism on PS5 and DirectStorage PC games. The heatsink’s futuristic design adds style to heat control, now with RGB lights.⁷ ⁸

¹ PCIe 4.0’s best theoretical sequential read is 8000 MB/s – 990 PRO reaches 7450 MB/s as of Q3, 2022. ² Sequential and random write performance was measured with Intelligent Turbo Write technology being activated. Intelligent Turbo Write operates only within a specific data transfer size. Performance may vary depending on SSD’s firmware, system hardware & configuration and other factors. For detailed information, please contact your local service center ³ Test system configuration: AMD Ryzen 7 5800X 8-Core Processor CPU @ 3.80GHz, DDR4 3600MHz 16GBx2 (PC4-25600 Overclock), OS – Windows 10 Pro 64bit, Chipset – ASRock-X570 Taichi ⁴ To maximize the performance of the 990 PRO, please check whether your system supports PCIe 4.0 at the Intel or AMD website. ⁵ 980 PRO Sequential Read/Write – 1,129/877 MB/Watt, 990 PRO Sequential Read/Write – 1380/1319 MB/Watt based on internal test result of 1TB capacity model. ⁶ PCI-SIG D8 standard spec: 8.8mm ⁷ DirectStorage technology from Microsoft loads games faster than before by leveraging the multiple GB/sec speed of modern NVMe SSDs. ⁸ Results are based on a comparison with Samsung 980 PRO ⁹ The LED display color may appear different from the color setting due to viewing angles and/or environmental factors
