内存条和固态硬盘是电脑主机中必备的两大存储元件,内存条负责读写数据,如同手机上的RAM一般;而固态硬盘负责存储数据,如同手机上的ROM一般。两种元件从原理、构造到功能、性能上都是有着很大差别的,属于两种不同的元件。那么内存条和固态硬盘有什么不同呢?下面就让小编给大家分析一下内存条和固态硬盘区别是什么。感兴趣的小伙伴们快来看看吧!
1.原理。内存条其实就是一种随机存取存储器,CPU能够通过总线寻址,并能够不分存储位置的读写,因此无论是读入还是写出,其速度都相当之快;而固态硬盘SSD是由NAND闪存颗粒、主控芯片组成,相比传统机械硬盘有着更为迅速的传输速率,虽然不及内存条,但好在能够长期的保存数据;
2.特性。内存条的存储容量,即内存条可以容纳的二进制信息量,通常DDR 3的容量在1GB~8GB之间,而DDR 4的容量则可以达到16GB。目前装机最常见的内存容量基本为16GB,当然也有更大的选择。在存取速度上,作为随机存取存储器的DDR,其存储周期(两个独立存取操作之间所需最短时间)仅需60纳秒~100纳秒,速度相当之敏捷。
固态硬盘目前的主流容量是128GB起步,1TB/2TB的也渐成主流;在读写速度上,因为固态硬盘移除了机械硬盘中的一系列机械结构,主要采用闪存颗粒作为介质,同时也不再需要磁头,因此其寻道时间几乎为零,能够提供惊人的连续书写速度。目前主流的固硬盘,其读写速度能够达到500MB/s,和传统的机械硬盘已经完全不是一个水准的了。除此之外,固态硬盘还具有更好的防震性、更低的功耗。
3.功能。内存条主要充当系统和程序临时数据的存储介质,能够实现和CPU高速的数据互换;而固态硬盘则是计算机的主要存储器,能够长久的存放大量数据信息。
以上就是小编为大家整理的内存条和固态硬盘区别的分析,希望对大家有所帮助!
