I tried making store benchmark based on caching settings on Windows which look like this: http://www.windows7library.com/blog/wp-content/uploads/2011/07/Write-Caching-Policy.jpg
both options checked: desktop 690 per sec, laptop 490 per sec caching checked (enabled), second one not checked (which is default setting): desktop 18 per sec, laptop 480 per sec neither checked: desktop 17 per sec, laptop 9 per sec All is still very far from more than 20 000 on linux in virtual box on the same PC. Also pretty curious how it has different influence on them. I should note that desktop HDD is much older - laptop is 3 years old, but desktop HDD is WD Blue WD6400AAKS made almost 8 years ago. However, disc monitoring utilities report that it is in perfect health (but still old, technologies improved since then I believe).
