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";
