具有RAID1 0的HP P410上的磁盘性能非常低

我有HP Microserver N54L,直到最近我使用集成软件raid没有问题.
我的raid阵列有2x WD Black和2x WD Red(非专业)磁盘.我也直接在主板上安装了SSD(并不重要,只是为了得到所有事实).

我购买了带有256MB内存的HP P410,带有Battery Back Write Cache模块.

我正在使用esxi 5.1,我有一个Windows虚拟机.在这台Windows机器中,我的读取速度非常快(仅高达40-60 MB / s)写入速度有点好(大约100MB / s),但仍比我使用集成raid时慢.

例如,这是将一个大文件从raid复制到ssd http://img.hihi.si/Upload/vYbD.png 🙁

这是我的raid控制器和数组信息

有什么想法怎么办?我需要提供更多信息吗?

>您将4k扇区( Advanced Format)磁盘和512字节驱动器混合在同一阵列中.这是一个考虑因素.
> WD红色和黑色磁盘驱动器 have different characteristics. >您期待什么类型的表现? ESXi与软件RAID不兼容,您正在比较正确的东西吗?如果您将另一个操作系统与ESXi进行比较,则这不是有效的比较. >调整RAID控制器缓存比率以偏向写入,而不是50:50. > MicroServer是一个缓慢的系统.
