The Samsung 990 EVO Plus doesn’t just meet expectations—it exceeds them, making it a standout choice for anyone who values speed.

Large Storage Capacity with Intelligent TurboWrite 2.0

With a 4TB capacity, the Samsung 990 EVO Plus offers massive storage space without sacrificing performance. This is especially important for users who work with large files—think 4K/8K video, RAW photos, game libraries, or virtual machines. A 4TB drive gives you room to store your entire digital life without constantly worrying about running out of space.

What sets this drive apart is Intelligent TurboWrite 2.0, Samsung’s next-generation write acceleration technology. Unlike traditional SLC caching, which uses a small, fixed portion of NAND as a fast write buffer, TurboWrite 2.0 dynamically allocates more space based on workload and available capacity. This means that during large file transfers—like copying a 100GB video project—the drive can sustain high write speeds for longer periods before dropping to baseline performance.

In real-world use, I transferred a 120GB folder of mixed media files (videos, photos, documents) and was impressed by how consistently fast the write speeds remained. Even after the initial burst, the drive didn’t slow down dramatically, thanks to the intelligent buffer management. This feature is a game-changer for users who regularly move large datasets, ensuring that performance doesn’t degrade under sustained loads.

Exceptional Thermal Control

High-speed SSDs often come with a downside: heat. As data is processed at extreme speeds, the controller and NAND can generate significant thermal output, leading to throttling and reduced performance. Samsung has addressed this with a nickel-coated controller that improves heat dissipation and reduces power consumption. This coating acts as a passive heatsink, helping the drive maintain optimal temperatures even during prolonged workloads.

During stress testing, I monitored the drive’s temperature using Samsung Magician software and found that it rarely exceeded 65°C, even under continuous read/write operations. This is well within safe operating limits and far below the throttling threshold. For laptop users, this is especially important—overheating can drain battery life and reduce component lifespan. The Samsung 990 EVO Plus’s efficient thermal design ensures that it runs cool and quiet, whether you’re gaming, rendering, or multitasking.

While the drive doesn’t include a physical heatsink, its low-profile design makes it compatible with most laptops and small-form-factor PCs. For desktop users who want extra cooling, adding a third-party M.2 heatsink is easy and highly recommended for sustained workloads.

Optimized Performance with Hybrid PCIe Support

The Samsung 990 EVO Plus supports both PCIe Gen 4×4 and PCIe Gen 5×2, making it one of the most versatile SSDs on the market. This hybrid approach means you don’t need the latest Gen 5 motherboard to enjoy top-tier performance. If you’re using a Gen 4 system, the drive will run at full Gen 4 speeds. If you upgrade to a Gen 5 platform later, it will automatically adapt to take advantage of the increased bandwidth.

This backward and forward compatibility is a huge advantage for users who want to future-proof their builds. You can install the Samsung 990 EVO Plus in a current-gen system and still benefit from its speed, knowing it will perform even better when you upgrade your motherboard. In my testing on a Gen 4 platform, the drive delivered consistent performance with no compatibility issues. The system recognized it immediately, and benchmarks confirmed near-maximum throughput.

Additionally, the drive’s support for HMB (Host Memory Buffer) technology allows it to use a portion of your system’s RAM as a cache when its own DRAM is limited. This is particularly useful for lower-capacity models or systems with limited onboard memory. While the 4TB version includes its own DRAM, HMB ensures that even if you use a smaller capacity, performance remains smooth and responsive.

Never Miss an Update with Samsung Magician Software

One of the standout software features of the Samsung 990 EVO Plus is integration with Samsung Magician, a powerful utility that helps you monitor, optimize, and maintain your SSD.
