Chrome OS netbooks do not have HDDs but instead they use flash based memory solutions or solid state drives (SSD) for that.

ChromeOS上网本并没有硬盘驱动器（HDD），而是采用了基于闪存的内存解决方案或是固态硬盘（SSD）。

And while the capacity of HDDs has grown exponentially, the speed of these devices has not significantly increased.

而当HDD的容量指数级增加时，这些驱动器的速度并没有实现显著增长。

One of the databases had its data stored on EFDs; the other had its data stored on similarly configured FC HDDs.

其中一个数据库将数据存储在EFD中；另一个将数据存储在有相似配置的FCHDD上。

And this type situation has only worsened as the density and capacity of HDDs have increased.

而且这种状况只会随着HDD密度和容量的增加而变得更坏。

Therefore, seek time continues to be the largest source of latency in HDDs.

因此，寻道时间一直是HDD的延迟时间的最主要来源。

As shown in Figure 3, monitoring showed 100% utilization on the FC HDDs and DA processors.

如图3所示，监控显示FCHDD和DA处理器的使用率为100%。

Because EFDs have no moving parts, they are not constrained by seek time or rotational latency in the way that FC and SATA HDDs are.

因为EFD没有移动的部件，所以它们不会像FC和SATAHDD那样受到寻道时间或旋转延迟时间的约束。

But although SSD costs are declining every quarter, SSDs are still more expensive than HDDs.

但是，虽然SSD的成本每个季度都在递减，但是SSD仍然比HDD昂贵。

SSDs can perform operations concurrently; HDDs cannot.

SSD可以并发执行操作；而HDD不可以。
