移动硬盘盒

移动硬盘盒 目前市面上的移硬盒主要分两:一是支持笔本硬的动动动动动动动动动动动动动动动动动动动动动动2.5英寸的硬盒动动，分薄和厚,,另一是支持普通动动动动动动动动动动动动动动动动动动3.5英寸硬的硬盒。本文将首动动动动动动动动动动先以可支持笔本硬的动动动动动2.5英寸移硬盒例,来大家介移硬动动动动动动动动动动动动动动动动动盒在之前您所知道的事情。动动动动动动动动动动动动动动 ?移硬盒的接口动动动动动动动 目前主流2.5英寸移硬盒的接口主要有两:动动动动动动动动动动动动动USB、IEEE1394。 USB接口的移硬盒是目前的主流品,其最大点是使用动动动动动动动动动动动动动动动动动动动动动 方便,支持插拔和即插即用,动动动动动动动动动 在Windows Me/2000/XP下无安装程序即动动动动动动动动可正常工作。根据准的不同,动动动动动动USB接口分动1.1和2.0动动动动动动动动动准,它之最大的区就是速度的不同,动动动动动动动动USB1.1接口的速度只有动动动动动动12Mbps,而USB2.0接口的速度动动动动高达480Mbps。因动USB动准的向下兼容,所以目前所有主板上的USB接口都可以支持1.1动准,但2.0动准只在最新的主板上才提供。尽管USB2.0动动动动动动准的硬盒价格比1.1动动准的要100元左右,但其速度性能的提高是的，当大的数据,动动动动动动动动动动动动动动动1.1动动动准接口那漫动动动动动动动动动动动动动动动动的等待在人心,。因此尽量USB2.0接口的移硬盒,就算你的动动动动动动动动动主板不支持,也可以今后的升留下余地或者再配一动动动动动动动动动动动动动动动动USB2.0接口卡。 IEEE1394俗称火,接口的数据率理上可达到“动”动动动动动动动动动动动动动动动动400Mbps。但由于IEEE1394接口在如今的主板上并不普及,因此往往需要配一价格不菲的用动动动动动动动动动动IEEE1394接口卡才能工作。因此,致付出的成本高,且不同的算机之动动动动动动动动动动动动动动动动动动动动动动动不易通用,不适合于大部分普通用。但在某些从事制、画、美动动动动动动动动动动动动动动动工工作的消者来,在动动动动动动MAC机和PC机上移数据,是非常需要动动“动”火接口的帮助的。 动动TIPS:熟知您的使用境,然后决定什接口的硬盒,是您需要做的第一动动动动动动动动动动动动动动动动动动动动动动。步 ?移硬盒的源动动动动动动动 动动动动动动动动动动动动动动动动动于硬盒的源,一点主要是USB接口的移硬盒的朋友的。由于动动动动动动动动动动动USB口的最大供动动动流500毫安,在某些候,不能足一些动动动动动动动动动2.5英寸硬工作的要求。如果动动动动动动动动动硬期在低于定流下工作,那就很容易出甚至坏。动动动动动动动动动动动动动动动动动动动动动动动动动动 其表硬常失数据、格式化无法完成示出、以及动动动动动动动动动动动动动动动动动动动动动动动动动动 在某些算机，尤其是笔本,上无法使用。动动动动动动动动动动动动动动动动动动动 如果,你只能可以使用外接源的硬盒或一条动动动动动动动动动动动动动动动动动动动动动动动动动USB-PS2接口取来解动动动动决,不有的硬盒采用低温内置源的,可以免去动动动动动动动动动动动动动动动动动动动动动动动动 外携外置器的麻。如果你是使用旧式笔本硬,动动动动动动动动动动动动动动动动动动动动动动动动 也要留意此,早期型号的笔本硬耗量往往偏高,使用流动动动动动动动动动动动动动动动动动动动动动动动动动动700毫安~1200毫安的均有。 动动TIPS:朋友在硬盒的候,一定要事先注意察看一动动动动动动动动动动动动动动动动动动动动动 下配套笔本硬流的需求。动动动动动动动动动动动 ?移硬盒所用的芯片动动动动动动动动动 动动动动动“动”“动动”竟建移硬的目的,是要其中的数据起来的。因此那些用来控制数据吐吐的 “USB2IDE”动动动动动动动动动动动动动动动动动动接主芯片就得更加重要了。不可否,好的芯片 在速度上就是要快不少。目前市面上能到的用于移硬的芯片,主要有动动动动动动动动动动动动动动动动动动动动动动动动动动动动动动动动动动动动GL811芯片、CS8813系列芯片、ALi M5621芯片、ALiM5642芯片、NEC芯片、Oxford芯片、ISD300芯片，In-System,等。 据硬盒市里深人士分析,移硬盒的价格高低,和动动动动动动动动动动动动动动动动动动动动动动动动 其所用芯片有非常直接的系。我大致可把些芯片分高、中、动动动动动动动动动动动动动动动动动动低三大。高档方面,上述芯片中就有动动动动动动动动动动动动动动NEC、Oxford芯片,它芯片的动动动动动动动动平均成本价大在动动70,110元左右。中档方面,有ALi的芯片,成本价在20,50元之。而动动动低档方面,有动动GL811、CS8813等芯片,成本价也就10元,20元之。动动 目前公动动动动最好的USB/IEEE139
