Summary
Both the Lexar NM790 and Samsung 990 Pro 2TB SSDs offer substantial storage of 2TB with a PCIe 4.0 interface, tailored for high performance. However, the Samsung 990 Pro has slightly higher sequential read and write speeds, and also boasts impressive random read and write IOPS, making it superior for tasks requiring high random access performance.
The Samsung 990 Pro benefits from DRAM caching, enhancing its performance further compared to the Lexar NM790's HMB. It also has AES 256-bit encryption for enhanced security, which is lacking in the Lexar model. Another distinguishing feature is Samsung's higher number of controller channels, suggesting potentially better management and distribution of data for enhanced performance and durability.
While both drives offer a five-year warranty, the Lexar NM790 has a higher TBW rating, indicating potentially longer endurance under heavy write loads. On the other hand, Samsung's product consumes slightly more power, which is a consideration for energy-conscious users.
Recommendations
For Gamers and Content Creators: The Samsung 990 Pro 2TB is recommended due to its superior sequential and random performance, which are critical for gaming and content creation tasks.
For General Users Seeking Longevity: The Lexar NM790 might be more appealing due to its higher TBW rating, suggesting better durability for long-term use.
For Users Needing Secure Data Storage: The Samsung 990 Pro with its AES 256-bit encryption is the preferred choice for those needing additional data security.
