Maximum PCIe 4.0 interface performance
The Samsung 990 PRO is designed to push the PCIe 4.0 interface to its limits. The combination of high transfer speeds, a proprietary Samsung controller and efficient thermal management delivers a fast response when working, gaming or moving large files. Performance remains stable even under heavier loads that require simultaneous high-speed reading and writing.
Speeds up to 7450MB/s
With sequential read speeds of up to 7450MB/s and write speeds of up to 6900MB/s, the 990 PRO gets close to the maximum capabilities of the PCIe 4.0 interface itself. For the 4TB version, random read speeds reach up to 1600000 IOPS and random write speeds up to 1550000 IOPS, helping to accelerate the loading of applications, games and other demanding tasks.
Higher performance with better efficiency
High speed doesn't have to mean unnecessarily high power consumption. The design of the Samsung 990 PRO delivers up to 50% better performance-per-watt efficiency compared to the previous generation, so it can take full advantage of PCIe 4.0 with more efficient power management. The lower power requirements also help to reduce the amount of heat generated during intensive use.
Intelligent operating temperature control
A sophisticated thermal management system ensures stable performance under heavy loads. The nickel-coated Samsung controller, along with a heat spreader, helps dissipate heat, and the Dynamic Thermal Guard technology continuously monitors the SSD's operating temperature. If necessary, it optimises performance to keep the drive within a safe temperature range for long-term stable operation.
Ready for demanding gaming
The Samsung 990 PRO offers high random performance, which is especially noticeable when loading large amounts of game data. Compared to the previous generation 980 PRO, it delivers a significant increase in random performance and helps to reduce waiting times when loading game worlds and other data. It also supports Microsoft DirectStorage technology, which lets compatible PC games make more efficient use of the high speed of an NVMe SSD and accelerate data transfer to the system.
Samsung Magician for easy SSD management
The Samsung Magician software gives you a single place to keep your drive's status under control. It offers SSD health monitoring, performance measurement, optimisation tools and firmware update management. This not only helps you check the current status of your Samsung 990 PRO, but also keeps its settings and firmware up to date for reliable and efficient operation.
Samsung technology from memory to firmware
The Samsung 990 PRO uses the brand's own components and technologies, including V-NAND memory, DRAM, controller and firmware. Their synergy optimises performance, reliability and SSD management as a single unit. The drive benefits from Samsung's many years of experience in developing semiconductor memory and storage.
