For sequential write speeds, the 1TB version reaches 6700 MB/s, whereas the 500GB version is slightly lower at 5600 MB/s. In terms of random write speeds, the 1TB model achieves 1,300,000 IOPS, significantly surpassing the 500GB model's 1,100,000 IOPS.

Both models show a clear difference in performance, with the 1TB version excelling in both sequential and random write speeds. These variations indicate that the larger capacity model is more capable in write-intensive scenarios, making it more suitable for tasks that involve large data transfers or frequent write operations.

In conclusion, the WD Blue SN5100 1TB provides faster write speeds in both sequential and random categories compared to the 500GB model, reinforcing its edge in performance for demanding applications.

The Western Digital WD Blue SN5100 1TB outperforms the 500GB version in the PassMark benchmark results. The 1TB model achieves a score of 47478, while the 500GB model scores 31151. This indicates a significant difference in overall performance based on these benchmark tests.

The higher PassMark result for the 1TB version suggests it handles more demanding workloads with better efficiency, which is consistent with its faster read and write speeds in previous comparisons.

Overall, the WD Blue SN5100 1TB shows a stronger performance in benchmark tests, making it the more capable choice for users focused on raw performance metrics.

Both the Western Digital WD Blue SN5100 1TB and the 500GB model share many key specifications. Both use the M.2 form factor, feature HMB (Host Memory Buffer) for the SSD cache, and are NVMe SSDs with NVMe version 2 support. They also both rely on the WD Polaris 3 A101-000103-A1 controller, have a PCIe version 4 interface, and operate with 4 controller channels. Additionally, both models support QLC (Quad-Level Cell) NAND flash storage, have a 1.3 million hour MTBF (Mean Time Between Failures), and come with a 5-year warranty. Neither model has an integrated heatsink, supports encryption, or features RGB lighting.

The primary differences between the two models lie in their storage capacities and endurance. The 1TB version offers 1000GB of internal storage, while the 500GB version provides 500GB. Furthermore, the Terabytes Written (TBW) rating for the 1TB model is 600, double that of the 500GB version, which has a TBW of 300. These differences highlight the increased endurance of the 1TB version, making it better suited for more intensive use over time.

In conclusion, while both models are very similar in design and features, the 1TB version offers more storage and greater endurance, which could make it a better fit for users with heavier usage demands or those needing more capacity.
