Below you'll find the benchmark scores for the Atlas 10K as well as the Atlas 10K II. By looking at the synthetic numbers, one can clearly see that the 10K II indeed offers a substantial increase in harddisk performance. Click on the image to get a full screen version.



Fig 4. ATTO Disk Bench, Atlas 10K, notice that average write speed levels out to 23 MB/s after the block size has increased to 32KB.



Fig 5. ATTO Disk Bench, Atlas 10K II, notice that average write speed levels out to 40 MB/s after the block size has increased to 32KB.



Fig 6. TCDLabs HDtach, Atlas 10K, notice that average access time is 8.3 ms and CPU utilization is 2.4%. Furthermore disk throughput is very constant, whether in the center or at the edge of the disk platter



Fig 7. TCDLabs HDtach, Atlas 10K II, notice that average access time is 7.1 ms and CPU utilization is 3.7%. Furthermore disk throughput is faster at the center of the disk than at the edge of the disk platter



Fig 8. SiSoft Sandra 2000, Atlas 10K, notice that buffered read and write speeds aren't much lower than those of the Atlas 10K II, even with the 8 MB buffer.



Fig 9. SiSoft Sandra 2000, Atlas 10K II, notice that buffered read and write speeds aren't much higher than those of the Atlas 10K, even with the 8 MB buffer.
