机器已经不在了。但配置不高，C1.0   815PE主板，8M高速硬盘，512内存。不过主板当时很贵的有1200多。

这是Raid 10

还是pc机，IDE硬盘


你的RAID10怎么测的这么高，我的DELL2950的SAS硬盘RAID10结果如下：
[root@db root]# hdparm -tT /dev/sda

/dev/sda:
Timing buffer-cache reads:   2952 MB in  2.00 seconds = 1476.00 MB/sec
Timing buffered disk reads:  462 MB in  3.00 seconds = 154.00 MB/sec

下面这个是dell2850，SCSI的硬盘RAID5结果如下：
[root@db2 root]# hdparm -tT /dev/sda

/dev/sda:
Timing buffer-cache reads:   3352 MB in  2.00 seconds = 1676.00 MB/sec
Timing buffered disk reads:  244 MB in  3.01 seconds =  81.06 MB/sec
[root@db2 root]# hdparm -tT /dev/sda

/dev/sda:
Timing buffer-cache reads:   3108 MB in  2.00 seconds = 1554.00 MB/sec
Timing buffered disk reads:  398 MB in  3.07 seconds = 129.64 MB/sec
[root@db2 root]# hdparm -tT /dev/sda

/dev/sda:
Timing buffer-cache reads:   3492 MB in  2.00 seconds = 1746.00 MB/sec
Timing buffered disk reads:  194 MB in  3.01 seconds =  64.45 MB/sec


这个测的到底准不准啊，怎么几次结果都不一样，并且SAS，RAID10的性能应该要比RAID5，SCSI的要好啊？ 另外这两个参数是什么意思，以那个为准，Timing buffer-cache reads:  / Timing buffered disk reads:
