Read speed:
sequential read speed 14700 MB/s 14900 MB/s
random read speed 1850000 IOPS 1600000 IOPS

The Samsung 9100 Pro 1TB and the Western Digital WD Black SN8100 1TB both offer impressive read speeds, but with slight differences in their specifications. For sequential read speeds, the Samsung 9100 Pro delivers 14,700 MB/s, while the WD Black SN8100 slightly outpaces it with 14,900 MB/s. The difference is minimal but notable for users who prioritize raw sequential speed.

When it comes to random read speeds, the Samsung 9100 Pro has a significantly higher value, offering 1,850,000 IOPS. In comparison, the Western Digital WD Black SN8100 offers 1,600,000 IOPS, which is still very fast but slightly lower than the Samsung model in this aspect.

In summary, while both drives offer high performance, the Samsung 9100 Pro stands out in random read speed, while the WD Black SN8100 has a small edge in sequential read speed.

Write speed:
sequential write speed 13300 MB/s 11000 MB/s
random write speed 2600000 IOPS 2400000 IOPS

The Samsung 9100 Pro 1TB and the Western Digital WD Black SN8100 1TB exhibit strong write speeds, with notable differences in both sequential and random write performance. In terms of sequential write speeds, the Samsung 9100 Pro offers 13,300 MB/s, which is faster than the WD Black SN8100's sequential write speed of 11,000 MB/s. This indicates a higher throughput for the Samsung drive during large, continuous data transfers.

Looking at random write speeds, the Samsung 9100 Pro also leads with 2,600,000 IOPS, while the WD Black SN8100 provides 2,400,000 IOPS. The Samsung drive again outperforms the WD model, providing slightly higher performance for random write tasks that involve accessing smaller chunks of data in quick succession.

In summary, the Samsung 9100 Pro 1TB offers faster sequential and random write speeds than the Western Digital WD Black SN8100 1TB, making it the stronger performer in both areas.

Benchmarks:
PassMark result 81351 79571

The Samsung 9100 Pro 1TB and the Western Digital WD Black SN8100 1TB show slightly different results in the PassMark benchmark. The Samsung 9100 Pro achieves a PassMark result of 81,351, while the WD Black SN8100 scores 79,571. This indicates that the Samsung model has a marginally higher benchmark score compared to the Western Digital drive.

The difference between the two products in PassMark results is not substantial, but the Samsung 9100 Pro holds a small lead in overall performance according to this benchmark.

Overall, while both drives perform strongly in the PassMark test, the Samsung 9100 Pro 1TB outperforms the Western Digital WD Black SN8100 1TB by a slight margin.
