U盘测试の量产过程及量产前后性能比较

桃扇骨 2021-11-09 23:18 353阅读 0赞

测试优盘：亿捷速豹CM981  
优盘大小：4G  
优盘芯片：ITE（联阳）IT1167  
Flash ID：EC D7 98 CA 54  
Flash型号：K9ABG08U0A\_MCB001  
量产软件：DtMPTool\_V1.67B.6.12D

在此仅测试实际应用中的速率。用量产前的数据和量产后的数据相比较。毕竟我们更加关注的是实际应用中的速度体验。一下是量产信息：

量产的时候涉及到修改的部分有：  
1.厂商信息（未改VID和PID）  
2.QC项目

3.参数输入：强行指定了Flash型号

4.分区设定：启动了两个公共分区，公共分区1的文件系统为FAT32，公共分区2则设置为CD-ROM，这次使用的ISO包是《深山红叶PE工具箱*V32*正式版》大小容量为495MB。文件系统为RAW。

量产完成之后，U盘能够正常使用USB-CDROM模式引导电脑。此时插入电脑会识别出一块可移动磁盘和一个光驱。接下来开始进行量产后的实际应用测试。测试软件Fastcopy v2.03。测试的数据标准请查看我之前写的测评《[U盘测试の亿捷EAGET速豹优盘系列对决\[U5\]比拼\[CM981\]][U_EAGET_U5_CM981]》

经过如此的测试之后，终于意识到量产之后速度下降的恐怖，看来这款芯片是不适合做量产了。所以对与自己剩下的那款盘，打死我也不会去量产了！
