由于内存卡无法进行2次维修，镭威视承诺为您半年保换服务（内存卡表面存在刮伤，压痕，出现缺口，印刷字符缺失，金手指断裂等情况，不在本保换范围内）

在购买存储卡之后，细心的人会发现，在操作系统当中存储卡的容量与官方标称的容量不符，都要少于标称容量，容量越大则这个差异越大。

标称512MB的存储卡，在操作系统中显示只有490MB左右；

1GB的存储卡只有980MB左右；

而4GB的存储卡则只有3.7GB左右。

这并不是厂商或经销商以次充好欺骗消费者，而是存储卡厂商对容量的计算方法和操作系统的计算方法不同和单位转换关系的不同造成的。

众所周知，在计算机中是采用二进制，这样造成在操作系统中对容量的计算是以每1024为一进制的，每1024字节为1KB，每1024KB为1MB，每1024MB为1GB；

而存储卡厂商在计算容量方面是以每1000为一进制的，每1000字节为1KB，每1000KB为1MB，每1000MB为1GB，这二者进制上的差异造成了存储卡容量“缩水”。

以4GB的存储卡为例：
厂商容量计算方法：4GB＝4,000MB＝4,000,000KB＝4,000,000,000字节
换算成操作系统计算方法：4,000,000,000字节/1024＝3,906,250KB/1024＝3,814.697265625MB＝3.8GB

同时在操作系统中，存储卡经过格式化，这样系统还会在存储卡上占用一些空间，提供给系统文件使用，所以在操作系统中显示的存储卡容量和标称容量会存在差异。

我们平时使用的硬盘等存储类型设备都是以这种计算方式得出的容量，容量越大偏差就会越大，比如40GB的硬盘只有37GB左右，这都是正常的容量。。
