Performance
The Samsung 990 Pro excels in both sequential and random read/write speeds, utilizing its PCIe 4.0 interface to reach up to 7,450 MB/s read and 6,900 MB/s write speeds. These speeds make it suitable for tasks like 4K video editing, high-resolution gaming, and heavy multitasking. Compared to its predecessor, the 980 Pro, the 990 Pro offers a noticeable performance boost, especially in random IOPS, which enhances responsiveness in applications that involve numerous small files.
For gamers, the 990 Pro improves load times and texture streaming in high-demand games, helping to reduce stuttering and create smoother gameplay. Content creators also benefit, as the SSD significantly reduces project save and load times, making it well-suited for software like Adobe Premiere Pro, DaVinci Resolve, and Photoshop.
Thermal Management
Samsung has implemented a nickel coating on the controller and a heat spreader on the NAND, effectively controlling heat output even under heavy workloads. Additionally, the 990 Pro offers an optional heatsink model with RGB lighting, enhancing both thermal efficiency and aesthetics for those with a clear PC case.
Power Efficiency
Samsung designed the 990 Pro with an improved power efficiency over previous models. This SSD uses up to 50% less power during idle and heavy use, which translates to longer laptop battery life and better overall power management for desktop users.
Software and Features
The 990 Pro is compatible with Samsung’s Magician software, which provides users with real-time monitoring, firmware updates, performance benchmarking, and customization options. The software enables users to optimize their SSD for different scenarios, such as gaming or content creation, and includes Samsung’s Dynamic Thermal Guard to prevent overheating.
