测试时，不要在磁盘上放重要数据，有数据的话先做快照备份，最好是全新盘测试

磁盘压测工具理论上都有损坏文件系统的可能，如果盘里有数据，压测前一定先做快照，压测完毕后回滚快照还原回去，确保不因压测磁盘丢数据。

1、微软推荐diskspd，参考https://cloud.tencent.com/developer/article/1835975

2、开源跨平台工具fio，参考https://cloud.tencent.com/developer/article/1836176 （Windows上优先推荐diskspd，其次fio）

特定场景磁盘压测示例：https://cloud.tencent.com/developer/article/2498227

fio.exe、diskspd.exe如何获取？

常规命令示例：

#指定128k
diskspd.exe -o32 -b128k -w0 -d120 -Sh -D -L -c10G E:\targetfile\IO10.dat
diskspd.exe -o32 -b128k -w0 -d120 -Sh -D -L -c10G F:\targetfile\IO10.dat
diskspd.exe -o32 -b128k -w0 -d120 -Sh -D -L -c10G G:\targetfile\IO10.dat
