Upgrading your computer’s storage can feel like a daunting task. You’re bombarded with options, and choosing between two top-tier drives like the Samsung SSD 990 Pro and the Samsung SSD 970 Evo Plus can be especially confusing. This comprehensive guide breaks down the key differences, helping you decide which SSD is right for your needs and budget.
Performance Comparison: Speed and Endurance
This section will delve into the performance differences between the Samsung SSD 990 Pro and the Samsung SSD 970 Evo Plus, examining their sequential read and write speeds, random access times, and overall endurance. We’ll look at real-world examples to show how these differences translate to practical usage.
Sequential Read and Write Speeds
- The Samsung SSD 990 Pro boasts significantly higher sequential read and write speeds compared to the 970 Evo Plus. This means that large files, such as videos and games, will transfer much faster on the 990 Pro. A typical 4K video might transfer in under a minute on the 990 Pro, whereas it could take several minutes on the 970 Evo Plus.
- This difference is largely due to the 990 Pro’s use of PCIe 4.0 interface, offering double the bandwidth of the 970 Evo Plus’s PCIe 3.0 interface. The faster data transfer rate translates to noticeable improvements in application loading times and overall system responsiveness.
Random Access Times
- While sequential speeds are important for large file transfers, random access times are crucial for overall system responsiveness. Random access refers to how quickly the drive can access small pieces of data scattered across the drive. The 990 Pro generally has slightly faster random access times, leading to a snappier user experience.
- This improvement in random access is particularly noticeable when working with multiple applications simultaneously, or when loading operating system files. The shorter wait times contribute to a more fluid and efficient workflow.
Endurance and TBW Rating
- The Samsung SSD 990 Pro typically comes with a higher Terabytes Written (TBW) rating than the 970 Evo Plus. TBW represents the total amount of data that can be written to the drive over its lifespan. A higher TBW indicates a longer lifespan, especially beneficial for users who frequently write large amounts of data.
- For example, a video editor or a database administrator might benefit greatly from a higher TBW rating as they are constantly writing and overwriting data. A higher TBW rating provides peace of mind, knowing that the drive is built to withstand intensive write operations for a longer duration.
Interface and Compatibility
This section discusses the different interfaces used by the Samsung SSD 990 Pro and 970 Evo Plus, their compatibility with various systems, and the impact of the interface on performance.
PCIe 4.0 vs. PCIe 3.0
- The Samsung SSD 990 Pro uses the PCIe 4.0 interface, offering double the bandwidth of the 970 Evo Plus’s PCIe 3.0 interface. This leads to noticeably faster transfer speeds, especially for large files. This is a critical difference for users who frequently transfer large amounts of data.
- To utilize the full potential of the PCIe 4.0 interface on the 990 Pro, your motherboard and CPU must also support PCIe 4.0. If your system only supports PCIe 3.0, the 990 Pro will still work, but its performance will be limited to the capabilities of the PCIe 3.0 interface.
M.2 Form Factor
Both drives utilize the M.2 form factor, making them compact and easy to install. This small size is ideal for laptops and smaller form factor desktops. The installation process is generally straightforward and requires minimal technical expertise. Many online tutorials and guides can assist users with the installation.
Compatibility with Different Motherboards
- Both the Samsung SSD 990 Pro and 970 Evo Plus are generally compatible with most modern motherboards, but always check your motherboard’s specifications to ensure compatibility before purchasing. Pay close attention to the supported NVMe protocols and PCIe versions.
- Incompatibility issues can arise if the motherboard doesn’t support the specific NVMe protocol or PCIe version used by the SSD. Before purchasing, cross-referencing the specifications of the SSD and your motherboard is crucial.
Features and Technologies
This section examines the advanced features and technologies incorporated into both SSDs, including their controllers, memory chips, and power management features.
Controller and NAND Flash Memory
- Both SSDs use advanced controllers and high-quality NAND flash memory for optimal performance and reliability. The specific controllers and memory chips used might differ, resulting in subtle performance differences.
- The choice of controller and flash memory significantly impacts performance and endurance. Samsung employs high-end components known for their reliability and speed in both the 990 Pro and 970 Evo Plus, but the 990 Pro utilizes newer, more efficient components.
Power Management and Thermal Throttling
- Both drives incorporate power management features to optimize power consumption and reduce heat generation. However, the 990 Pro might have slightly more advanced power management features, leading to potentially lower power consumption under heavy loads.
- Thermal throttling, a reduction in performance to prevent overheating, is a common issue with high-performance SSDs. While both drives have thermal management solutions, the 990 Pro’s design might minimize thermal throttling more effectively.
Firmware Updates and Samsung Magician Software
Samsung provides firmware updates for both SSDs through its Magician software. These updates often improve performance, add new features, or address bugs. Regular firmware updates are recommended to keep your SSD running optimally and securely.
Price and Value

Value Proposition
- The Samsung SSD 990 Pro generally commands a higher price point than the 970 Evo Plus due to its superior performance and features, particularly its PCIe 4.0 interface and higher TBW rating. This higher price reflects its significantly faster transfer speeds and longer lifespan.
- The 970 Evo Plus, while not as fast, offers excellent performance for its price and represents a good value for users who don’t require the highest speeds or longest lifespan. It remains a strong contender for users seeking a balance of performance and affordability.
Case Study: Gaming Performance
- A gamer using the 990 Pro reported significantly faster loading times in demanding games like Cyberpunk 2077 compared to using a 970 Evo Plus. The faster loading times reduced wait times and improved the overall gaming experience.
- In contrast, a user primarily using their computer for office tasks found the performance difference between the two drives to be negligible. For everyday tasks, the 970 Evo Plus provided sufficient speed without the extra cost.
