在计算机界,我们总是会听到各种各样神奇而又独特的专有名词,如 USB 、 SSD 等等,ssd硬盘作为最近电脑市场的新秀正在逐渐地渗透到我们的生活之中,但是不少都不了解ssd硬盘是什么?为什么这么贵?以及它有哪些优点。下面,小编就来跟大家讲解ssd固态硬盘。
当前固态硬盘越来越便宜,人们选购电脑也越来越喜欢加入固态硬盘,对于很多电脑新手用户来说,可能对固态硬盘有什么用或者固态硬盘是什么都缺乏认识,有的用户问ssd固态硬盘是什么?下面,小编就来跟大家聊聊ssd固态硬盘。
ssd固态硬盘是什么
SSD 的含义
所谓 SSD ,英文全称是 Solid State Drives ,即为固态硬盘。说到硬盘我想很多人都知道是什么意思,硬盘是计算机内部非常重要的硬件设备,它的主要功能就是存放计算机内部的数据和文件,是计算机内部的一个主要仓库。硬盘一般分为两个类型,一种是机械硬盘,另外一种就是固态硬盘。固态硬盘是使用固态电子芯片阵列制成的硬盘,一般由存储单元和控制单元组成,固态硬盘是目前最主流的一种硬盘,而且在可预见的未来当中,短时间内很难会被其他硬盘替代。

固态硬盘的优点:
1、读写速度快:
SSD不用探头读取数据,而是逻辑电路读取数据,寻道时间接近于0。SSD的持续读写速度非常快,一般在售产品都超过500MB/s,而机械硬盘一般只有200MB/s。机械硬盘的随机读写速度一直被人诟病,而SSD的随机读写速度很快,这使日常操作都非常流畅了。使用SSD的电脑开机时间能达到10s以内。

2、防震抗摔性好:
传统机械硬盘顾名思义,是机械化的结构,由磁片,转动马达,机械探头等组成,摔后探头容易错位,马达也容易坏,磁片容易划伤,总之不耐摔。而SSD是由闪存颗粒焊接在电路板上组成,不存在任何机械部分,抗震性好。

3、功耗低:
一个机械结构一个逻辑电路,机械需要更高的能量。

4、噪音为零:
机械硬盘工作中,马达会带动磁片转动,探头触碰磁盘,这些都会发出噪音。SDD纯逻辑电路,没有噪音。

5、环境适用性强:
传统的机械硬盘对温度敏感,温度过高或过低都会损害磁片,对马达的转动也有影响。而SSD对温度要包容的多,可以在-40~85度的环境中使用。

SSD目前售价来说,128G固态硬盘和500G机械硬盘接近,目前又是云计算云存储的趋势,本地磁盘容量的需求越来越少,按大多数人使用来看,128GB其实够用。如果您有大容量的本地存储需求,编辑推荐在SSD的基础上加一块机械硬盘,这样速度和容量都保证。
以上就是关于ssd固态硬盘的介绍了。
