Samsung Adds 4TB Capacity to 990 PRO Series

The 990 PRO and 990 PRO with Heatsink now offer more space for games and files, and boast best-in-class speeds


Samsung Electronics America today announced the release of a new 4-terabyte (TB) offering in its SSD 990 PRO series for gamers and creators. The 990 PRO series includes high-performance PCIe1 4.0 SSDs powered by eighth-generation Samsung V-NAND (V8) technology and an enhanced proprietary controller.

Offering blazing-fast speeds and ultimate power efficiency, the 990 PRO series is optimized 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.

“We recognize that people need more innovative storage options to meet their day-to-day needs – whether they’re downloading games over 100GB or accessing high-resolution content that shows beautifully vivid detail, the Samsung 990 PRO 4TB series delivers the perfect solution, enabling people to save even more games and content to their libraries without compromising on download or upload speeds,” said Jose Hernandez, Senior Director of Memory Product Marketing at Samsung. “The 4TB doubles the maximum capacity of the Samsung 990 PRO series, its fastest drive, while keeping a slim design to fit into an ultra-thin laptop or game console – so no matter the system, you can upgrade the storage in your device.”

Best-in-class Performance and Capacity

Featuring Samsung eighth-generation V-NAND technology and an improved controller, the 4TB 990 PRO and 990 PRO with Heatsink offers nearly the highest speed currently available from the PCIe 4.0 interface2, 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 IOPS3 respectively, making it the ideal solution for gamers, creative professionals and technology enthusiasts seeking top-tier performance and large storage space.

With the fastest random read performance among the PCIe 4.0 interface consumer SSDs on the market4, the 4TB 990 PRO series significantly reduces mid-game stalls and accelerates the loading of high-quality videos. This gives gamers uninterrupted gaming sessions and an immersive experience. Content creators will see their videos load faster, saving them time to edit or keep creating.

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 also equipped with an effective, slim heatsink. 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 the Samsung V8 1Tb high-density NAND and its memory stacking technology, the 4TB 990 PRO series is designed with a single-sided M.2 form factor, which makes it slimmer than other double-sided M.2 SSDs. The single-sided M.2 form factor of the Samsung 990 PRO series can be installed in ultra-thin laptops without worry.

Availability & Samsung Magician Software

The 990 PRO 4TB (MSRP: $344.99) and 990 PRO with Heatsink (MSRP: $354.99) will be available for purchase at and select retailers in October 2023. The 1TB and 2TB models of the 990 PRO series are currently available for purchase.

Samsung Magician software ensures optimal performance in SSDs by keeping firmware, drivers and other settings up to date, while also offering the flexibility to customize power and performance optimization. Moreover, the software supports RGB functionality for the 990 PRO with Heatsink, so gamers have the option to customize color and LED effects. The new version of Magician 8.0 is set to be released later this month, ahead of the 4TB 990 PRO series availability. It is an integrated software solution for Samsung SSDs, portable SSDs, memory cards and USB flash drives.
