内存条对于电脑来说是至关重要的。随着电脑技术的飞速发展,SSD固态硬盘也越来越普遍,那么内存条和固态硬盘区别有什么?下面就为大家详细介绍一下两者之间的区别。大家快来看看吧。
一、性质不同
1、固态硬盘:用固态电子存储芯片阵列而制成的硬盘。
2、内存条:CPU可通过总线寻址,并进行读写操作的电脑部件。
二、性能不同
1、固态硬盘:
(1)读写速度快:采用闪存作为存储介质,读写速度比机械硬盘快。固态硬盘不需要磁头,寻道时间几乎为零。连续的书写速度是惊人的。大多数固态硬盘制造商都会宣称自己的固态硬盘读写速度超过500MB/s。
(2)防震抗摔性:传统硬盘为磁盘型,数据存储在磁盘扇区。
(3)低功耗:固态硬盘的功耗低于传统硬盘。
2、内存条:
(1)存储容量:即存储条可以容纳的二进制信息量。例如,168个常用存储条的存储容量通常为32兆、64兆和128兆。而DDRII3普遍为1GB到8GB。
(2)存取速度(存储周期):即两个独立存取操作之间所需的最短时间,也称为存储周期,半导体存储器的存取周期一般为60纳秒到100纳秒。
(3)存储器的可靠性:存储器的可靠性是以平均故障间隔时间来衡量的,可以理解为两个故障之间的平均时间间隔。
(4)性能价格比:性能主要包括存储容量、存储周期和可靠性。性能价格比是一个综合性指标,对不同的存储器有不同的要求。
以上就是固态硬盘和内存条的区别介绍啦,希望能帮助到大家。
