Launching in Singapore this October, the 990 PRO and 990 PRO with Heatsink boast best-in-class random read speeds of up to 1600K IOPS

Samsung Electronics Co., Ltd., a world leader in advanced memory technology, announced the release of a new 4-terabyte (TB) offering in its SSD 990 PRO series. The 990 PRO series is a lineup of high-performance PCIe[1] 4.0 SSDs powered by Samsung’s eighth-generation V-NAND (V8) technology and enhanced proprietary controller.


Offering blazing-fast speeds and ultimate power efficiency, the 990 PRO series is optimised for massive data volumes, such as 3D/4K graphics work, data analytics and high-quality games, making it the ideal SSD for today’s PCs, laptops, game consoles and computing systems. With improved total bytes written (TBW) ratings of up to 2,400TB, the 990 PRO series ensures increased SSD reliability and longevity, ideal for those with highly demanding workloads and large storage capacity needs.


“Today’s gamers and creative professionals require high-capacity, high-performance SSDs and Samsung’s new 4TB SSD 990 PRO is the perfect storage solution to meet their needs,” said Hangu Sohn, Corporate Vice President of the Memory Brand Product Biz Team at Samsung Electronics. “As the demand for high-resolution content and ultra-fast data-processing speeds continues to grow, high-performance NVMe[2] storage has become a core requirement.”



Best-in-class Performance and Capacity

Featuring Samsung’s V8 technology and improved controller, the 4TB 990 PRO offers near-max performance in a PCIe 4.0 interface, with sequential read speeds of up to 7,450 megabytes-per-second (MB/s) and write speeds of up to 6,900MB/s. The newly expanded capacity of 4TB delivers boosted random read and write speeds of up to 1,600K and 1,550K IOPS[3] respectively, making it the ideal solution for gamers, creative professionals and tech enthusiasts seeking top-tier performance and storage space.


With the fastest random read performance among PCIe 4.0 interface consumer SSDs on the market[4], the 4TB 990 PRO significantly reduces mid-game stalls and accelerates the loading of high-quality videos, increasing gamers’ enjoyment and immersion. For high-end games that support the latest in game-loading technology, the 990 PRO series can help reduce lag, allowing users to enjoy real-time gameplay experiences with consistently high frames per second (FPS)



Enhanced Power Efficiency and Reliable Thermal Control

The 990 PRO series achieves breakthrough power efficiency, with an up to 50% performance improvement in comparison to the previous 980 PRO series. It also incorporates a nickel coating on the controller and features a heat spreader label on the back side of the SSD, ensuring optimal temperature level maintenance and minimal performance fluctuations over time. The 990 PRO with Heatsink is equipped with an effective, slim heatsink, giving users the full experience in sustained high-performance computing and gaming capabilities. Furthermore, the drive is compatible with the latest game consoles, so it can speed up game installation and loading times, while also preventing performance drops that can result from overheating.



Single-Sided 4TB SSD for Ultra-Slim Laptops

Thanks to Samsung’s V8 1Tb high-density NAND and the company’s memory stacking technology, the 4TB 990 PRO was designed with a single-sided M.2 form factor, which makes it slimmer than other double-sided M.2 SSDs. This frees users from the concerns that double-sided M.2 SSDs can cause when installed into ultra-thin laptops, such as an inability to install the SSD or the risk of damaging other components. With a single-sided M.2 form factor, the streamlined design provides abundant storage capacity and sustainable performance.



Samsung Magician Software and Availability 

The Samsung Magician software ensures optimal performance in SSDs by keeping firmware, drivers and other settings up to date, while also offering the flexibility to customise power and performance optimisation, according to user preferences. Moreover, the software supports RGB functionality for the 990 PRO with Heatsink, so gamers have the option to customise color and LED effects. Set to be released in September 2023, the new version of Magician 8.0 will be an integrated software solution for SSDs, portable SSDs, memory cards and USB flash drives.



Local Availability and Pricing

The 4TB 990 PRO series will be available on the Samsung Online Store, Lazada and Shopee, as well as major consumer electronics and IT retailers from 2 October 2023.
