That's hard to predict :-) |

You could try different stripe sizes and use a benchmark tool like |
11 |
bonnie to check the throughput. |

In general I'd assume that a mail server has to handle many small files, |
13 |
so a smaller stripe size should be better - 64k or 128k I guess. I |
14 |
haven't had any disk-related performance problems yet, I think the |
15 |
difference between 64/128/256k stripe size is negligible - but if in |
16 |
doubt test it yourself! |

Hope that helps, |
