SATA 6Gbps固态硬盘AHCI、IDE模式对比

Phoronix近日对Linux系统下固态硬盘运行于AHCI、IDE两种模式的不同性能进行了简单对比，不过鉴于后者是更先进的SATA模式，还支持NCQ、热插拔等功能，结果也在意料之中。

测试系统是Ubuntu 12.10。Linux内核自从2.6.19版开始就支持AHCI，最新的3.5版当然更没问题。所用固态硬盘是OCZ Vertex 3 240GB，SATA 6Gbps接口。

SATA 6Gbps固态硬盘AHCI、IDE模式对比

测试成绩如下：

除了BlogBench意外落后三分之一，AHCI在其它12个项目中均如期取得胜利，有时候甚至是好几倍的压倒性优势。既然现在Linux系统对AHCI已经支持得这么好，SATA 6Gbps硬盘自然就没必要考虑IDE模式了。

另外感兴趣的还可以看看机械硬盘在两种模式下的性能对比，这里和这里。
