php 测试硬盘读写-php 测试硬盘写速率

使用php写入一个1GB大小的文件，检查硬盘的写速率，可能有一定误差，

建议还是使用专业的硬盘测试工具来检测

一般电脑读写在20M/s，这个测试要执行大概40-50s

仅供参考：

<?php





set_time_limit(0);





$str = str_pad($str, 512, "0");





$file = fopen("./temp","a+");





$i = 0;





$bytes = 1000000000;





$mygabyte = $bytes/1000000;





echo "test start. waiting ...";





$starttime = time();





while($i < $bytes){





    $i += fwrite($file, $str);





}








$endtime = time();





$usetime = $endtime - $starttime;





$write_xiaolv = $bytes/$usetime;





$myga_xiaolv = $mygabyte/$usetime;





echo "create 1GB file use time ".$usetime." seconds\n";





echo "speed :".$write_xiaolv." byte/s\n";





echo "speed :".$myga_xiaolv." m/s\n";
