随着SSD固态硬盘的价格下降,以后组装电脑使用SSD固态硬盘将会成为主流,目前来说,SSD固态硬盘的容量偏小,并且价格比起机械硬盘来没有优势,比起普通机械硬盘来,价格之间的差距比较大。固态硬盘和普通硬盘的区别都有哪些呢?下面,小编就来跟大家讲解固态硬盘和普通硬盘的区别。
固态硬盘铺货已经有很长一段时间了,不过目前主流装机依然都是选购传统的机械硬盘,而对于固态硬盘则多数出现在高端配置装机中,由于目前固态硬盘容量较小,价格高,有用户就问了固态硬盘和普通硬盘有什么区别,下面,小编就和大伙聊聊固态硬盘和普通硬盘的区别。
固态硬盘和普通硬盘的区别
固态硬盘和普通硬盘的区别
1. 固态硬盘启动快,没有电机加速旋转的过程。
2. 固态硬盘不用磁头,快速随机读取,读延迟极小。根据相关测试:两台电脑在同样配置的电脑下,搭载固态硬盘的笔记本从开机到出现桌面一共只用了18秒,而搭载传统硬盘的笔记本总共用了31秒,两者几乎有将近一半的差距。

3. 相对固定的读取时间。由于寻址时间与数据存储位置无关,因此磁盘碎片不会影响读取时间。
4. 基于DRAM的固态硬盘写入速度极快。

5. 固态硬盘无噪音。因为不像普通硬盘那样有机械马达和风扇,工作时噪音值为0分贝。某些高端或大容量产品装有风扇,因此仍会产生噪音。
6. 低容量的基于闪存的固态硬盘在工作状态下能耗和发热量较低,但高端或大容量产品能耗会较高。

7. 固态硬盘内部不存在任何机械活动部件,不会发生机械故障,也不怕碰撞、冲击、振动。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,而且在笔记本电脑发生意外掉落或与硬物碰撞时能够将数据丢失的可能性降到最小。
8. 固态硬盘工作温度范围更大。典型的硬盘驱动器只能在5到55摄氏度范围内工作。而大多数固态硬盘可在-10~70摄氏度工作,一些工业级的固态硬盘还可在-40~85摄氏度,甚至更大的温度范围下工作。

9. 低容量的固态硬盘比同容量硬盘体积小、重量轻。但这一优势随容量增大而逐渐减弱。直至256GB,固态硬盘仍比相同容量的普通硬盘轻。
10.固态磁盘的价格较贵,是普通磁盘的2-3倍。
