SSD驱动器： OCZ Vertex EX 60 GB SATA II 2.5 Inch SSD

从各方面来看,它是“企业”应用程序中最受欢迎/评价最佳的单级单元SSD驱动器.他们的文献声称60GB型号：

>读取：最多260 MB
>写：高达200MB
>持续写入高达100MB
>寻求时间：小于.1ms

有一个非常好的基准和评论here.

硬盘驱动器：Western Digital Blue Caviar 80GB SATA II 7200 RPM Drive

这是我们在系统中找到的典型驱动器.文献声称：

>持续阅读&写入速度高达70MB / s
>平均寻道时间：4.2ms

该测试机是戴尔SC1425,2×3.6GHz Xeons,16GB内存.

因此创建了文件测试数据(HDD和SSD驱动器上的数据)：

sysbench –test = fileio –max-time = 60 –max-requests = 1000000 –file-num = 10 –file-extra-flags = direct –file-fsync-freq = 0 –file-total -size = 50G准备

因此创建了MysqL测试数据(HDD和SSD驱动器上的数据)：

sysbench –test = oltp –db-driver = MysqL –MysqL-socket = / tmp / MysqL.sock –MysqL-db = test –MysqL-table-engine = innodb prepare

注意：2.5英寸适配器机箱(2.5英寸驱动器适合3.5英寸插槽)不适用于Dell 3.5英寸驱动器底座,因为连接器对齐已关闭.假设使用这些SSD时需要2.5英寸背板,我们可能会使用R610.

注意：我也测试了zfs,xfs和ext4,以及软件RAID0中的两个SSD ……但是没有空间在这里发布它们,并且大多数情况下单个ext3 SSD表现最佳.我会做更多测试,但它似乎不喜欢软件raid.
