6Gbps:SATA新时速今年可能会露面

可能由于固态硬盘的快速发展,而加速SATA III接口标准的提早露面,预计首个展示平台可能会在今年晚些时候公开,比较当前的SATA II,新推出的SATA III接口标准带宽将从275MB/s提升到550MB/s。

    目前包括希捷和AMD都已经部分展示SATA III,也就是SATA 6Gbps接口硬盘相关技术,虽然希捷先前在美国新奥尔良展示的样品原型速度仍然没有固态硬盘快,不过据称持续数据传输率已经突破550MB/s,快过当前最快硬盘的5倍以上。

   

但是即便如此,用户也不能指望硬盘速度立刻能够达到550MB/s,因为希捷表示到2010年硬盘的数据传输性能可望超过200MB/s,但这只是当前最快固态硬盘的速度能力。

    而启用SATA 6Gbps的固态硬盘预计数据传输性能则能够达到500MB/s。

    目前最新一代的SATA技术还不能够做好预备出炉的准备,但是其相关技术细节,以及产品原型已经基本就绪,具体的产品预计今年晚些时候就可能进入商用化阶段。
