[参测选手介绍：西部数据VelociRaptor 300GB]

西部数据VelociRaptor 绰号“猛禽”，是西部数据桌面级产品中的最强系列硬盘，转速达到10000 RPM，根据官方数据，VelociRaptor采用2.5寸双碟设计，单碟容量150GB。这种高密度存储有利于提高寻道速度，其读取寻道时间为4.2ms，写入则为4.7ms。虽然小尺寸碟片对提高持续传输率不利，但西部数据仍然将其持续传输率从84MB/s提高到了120MB/s。2.5寸盘的好处还在于节能，VelociRaptor的正常运行功耗仅有6W。

机械硬盘之王

我们测试使用的VelociRaptor 300GB 单碟容量为150GB双碟封装，缓存16MB，在以往的传统硬盘测试中表现出了超群绝伦的性能，尤其是在两块西部数据VelociRaptor 300GB 组建RAID 0之后，性能更是达到了机械硬盘的顶峰，毫无争议的成为传统硬盘之王，详细测试可以参考加速！加速！西数万转硬盘猛禽RAID测试一文。
