U盘,或许我们人人身上都有,因为它很便宜,携带方便,还可以一键u盘装系统。但质疑u盘价格为什么相差那么大也大有人在,影响u盘价格因素是多方面的,U盘内存有32G到100多,价格几十到几百。看似空间是够的,除了U盘容量影响着u盘价格,还有什么因素呢?接下来,就让小编为你分析。
因为U盘用料的质量和技术的不同,价格相差很大。
一个U盘主要部件是主控和闪存,下面一一分析。
闪存:
闪存就是存储芯片,所有数据都在上面,闪存容量通常就是U盘容量,越大越贵。
闪存有多种技术,常见的有slc、mlc、tlc,三者速度依次降低,寿命依次缩短,价格依次减少。
闪存也有单通道和双通道之分。有时4g*2的双通道8gU盘比单通道8g*1的成本高,但双通道速度快。
闪存的切割工艺也有许多,越精细的功耗越小速度越快成本越高。
最后是供货商,不同牌子的闪存进价不一样,名牌的质量可靠稳定成本高。
主控:
主控是让闪存和电脑能互相识别的芯片。
主控决定了最大传输速度,优质主控快、稳定、不掉速,成本高。
主控决定了接口。支持usb3.0的主控比支持usb2.0的主控成本高很多。
有时为了速度使用ssd固态硬盘的主控,成本更高。
总结而论,上述简单分析影响u盘价格因素的全部内容介绍到此就结束了,u盘价格不仅仅是因为内存的大小决定着,影响u盘价格因素的还有U盘的质量,技术及主控等,在我们用U盘的同时,也可以多了解影响u盘价格因素,在购买U盘的时候,也就比较在行了!
