[7.参测硬盘之西部数据RE4 2TB]

西部数据RE4: WD2003FYYS-01T8B0 2 TB

通常情况下，厂商发布桌面产品的同时会随后推出企业级版本。而这款RE4 WD2003FYYS正是Caviar Black WD2001FASS的同门兄弟。两款硬盘拥有几乎完全一样的物理参数。唯一不同是，由于前者定位于企业级应用，还额外加入了主动电源管理、TLER（Time Limited Error Recovery，限时错误校正）和RAFF（Rotary Acceleration Feed Forward，震动补偿）技术。TLER可以避免由于时间过长的硬盘错误恢复过程造成硬盘出错。RAFF则能够实时纠正线性和旋转震动，让硬盘在震动环境下提供更好的性能。（需要提到是，我们在实测过程中发现不管是Caviar Black 还是RE4在停止工作时都会发出一种奇怪的声音，这在其它硬盘中都没有出现过，应该是硬盘监视器停止盘片发出的声音，不过无关大碍）
