测试不同硬盘不同raid情况下的服务器

Showfom

命令都采用

1. dd if=/dev/zero of=test bs=64k count=16k conv=fdatasync

复制代码

一律测试三次

结论，SSD很快但是不稳定，SAS性能比SATA2好多了，SATA2不能按照硬盘大小来比较，Raid1和Raid10的差距还是很大⋯⋯

建议：有实力的还是上SAS吧。。。。

SATA3如何

SATA3和SATA2没啥大的差别，买了台yesup的毒妇，说是SATA3，但是情况比SATA2还糟糕，所以就不放出了。

Kvm

dd if=/dev/zero of=test.bin bs=64k count=4k oflag=dsync

master

有趣

自己的MacBook Air，无法运行conv=fdatasync

1. dd: unknown conversion fdatasync

复制代码

1. Showfoms-MacBook-Air:~ Showfom$ dd if=/dev/zero of=test bs=64k count=16k
   
2. 16384+0 records in
   
3. 16384+0 records out
   
4. 1073741824 bytes transferred in 4.574604 secs (234717981 bytes/sec
