说起电脑硬盘的时候,我们会发现电脑硬盘主要分为固态硬盘和机械硬盘两类。有网友不知道该如何选择,二者有什么区别。下面就给大家详细讲下固态硬盘和机械硬盘有什么区别:
工具/原料:
系统版本:windows10系统
品牌型号:华硕a豆14
一、固态硬盘和机械硬盘简介
1、固态硬盘
固态硬盘又名固态驱动器,简称SSD,固态硬盘是由控制单元和存储单元(FLASH芯片、DRAM芯片)组成。固态硬盘在接口的规范和定义、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。
2、机械硬盘
机械硬盘简称HHD,是传统普通硬盘,其里面的零部件包括:磁盘盘片,磁头,盘片转轴及控制电机,磁头控制器,数据转换器,接口,缓存等组成。磁头可沿盘片的半径方向运动,加上盘片每分钟几千转的高速旋转,磁头就可以定位在盘片的指定位置上进行数据的读写操作。信息通过离磁性表面很近的磁头,由电磁流来改变极性方式被电磁流写到磁盘上,信息可以通过相反的方式读取。
二、固态硬盘和机械硬盘区别
1、本质不同:机械硬盘本质是电磁存储,固态则是半导体存储。
2、防震抗摔性不同:机械硬盘很怕率,固态抗震。
3、数据存储速度不同:固态读写速度比机械快。
4、功耗不同:固态硬盘的功耗比机械硬盘低。
5、重量不同:固态硬盘的重量比机械硬盘轻。
6、噪音不同:机械硬盘有噪音,固态硬盘没有噪音。
7、价格不同:固态硬盘比机械硬盘价格较为昂贵,性价比较低。
总结:
以上便是固态硬盘和机械硬盘的区别介绍,在选购电脑硬盘的时候,大家可以根据自己的需要选择合适的硬盘即可。
