全新行货正品支持任何官方验证假一罚十,享受官方3年质保。 今年六月份,西部数据发布了全球第一块容量高达1TB的7毫米超薄2.5寸[url=]硬盘[/url],实际表现也相当出色。如今,西数旗下的日立也发布了类似的产品,并且号称同类产品世界最快。——值得一提的是,日立是当年第一家推出7毫米硬盘的。
日立新盘隶属于Travelstar Z5K1000系列,容量1TB、750GB两种版本,均为双碟装,缓存32MB,转速5400RPM,接口SATA 6Gbps,内部数据传输率1061Mbps(133MB/s),平均寻道时间13ms,重量仅为95克,还支持SED自加密技术并符合TCG Opal加密规范。 这款硬盘的待机时噪音为21dB、寻道时噪音为22dB;功耗表现也不错——休眠0.1W、待机0.2W、低功耗待机0.5W、主动待机0.8W、性能待机1.5W、读写1.6W、寻道1.8W。 日立没有说明“世界最快”的名号从何而来。对比西数的,双方规格上几乎完全相同,但是西数140MB/s的内部数据传输率其实更高。
