2em">在2012年IDF大展上，消费级SSD固态硬盘首次展现在用户面前，随着时间的推移SSD固态硬盘经历了两个年头，而现在大家对它的了解依然停在速度快、价格高的认知上。那么SSD硬盘在应用中比机械硬盘到底快多少？近10倍的价格到底值不值？笔者在本次测试中就告诉您。<P style="TEXT-INDENT: 2em"><P><P style="TEXT-INDENT: 2em">固态硬盘（SSD ：Solid State Disk）是在传统条硬盘上衍生出来的概念，简单的说就是用固态电子存储芯片阵列（NAND FLASH）而制成的硬盘。固态硬盘的接口规范和定义、功能及使用方法上与普通硬盘的完全相同，在产品外形和尺寸上也完全与普通硬盘一致，包括3.5英寸、2.5英寸、1.8英寸等多种类型。<P><IMG border=0

2em">相对于机械硬盘，SSD的结构更为简单，一个PCB基板，数颗FLASH芯片+一颗主控芯片就构成了一个存储结构。正因为SSD硬盘的特殊结构，才使得它具有机械硬盘不可比拟的优势。<P style="TEXT-INDENT: 2em"><B>SSD硬盘相比传统机械硬盘优势在哪？<P style="TEXT-INDENT: 2em">首先，固态硬盘是内部使用闪存颗粒（flash，即目前存储卡、U盘等存储介质）制作而成，所以SSD固态硬盘内部不存在任何机械部件，这样即使在高速移动甚至伴随翻转倾斜的情况下也不会影响到正常使用，即便笔记本电脑发生意外掉落也能够将数据丢失的可能性降到最小。<P><IMG border=0 src="http://cimg2.163.com/catchimg/20140310/11478691_1.jpg"><P><P style="TEXT-INDENT: 2em">传统机械硬盘内部构造<P style="TEXT-INDENT: 2em">其次，依然是SSD硬盘不具备任何机械部件，所以硬盘中的寻道参数就不会再SSD硬盘中出现，那么高速的寻道时间使得SSD硬盘在加载软件，开机等操作中变得非常快。<P style="TEXT-INDENT: 2em">最后，就是SSD硬盘的其他特性如更低的功耗、更小的噪音、更轻的重量，也都是硬盘本身结构变革的有力证明。说了这么多好处，那么在真实应用中，SSD固态硬盘到底能超出机械硬盘多少呢？下面就通过测试给出答案。<BR/><BR/>'</span></font></div> <div class="moreaction"> <SCRIPT LANGUAGE="JavaScript"
