I’ll also show how to install and usehdparmutility for measuring read speed of a disk on Linux Mint, Ubuntu, Debian, CentOS, RHEL. To get the accurate read/write speed, you should repeat the below tests several times (usually 3-5) and take the average result. Cool Tip:How to choose...

Seq:Sequential Read/Write Test ,就是连续读写的测试,数据块的大小是1M(在学习SSD时经常看到“连续读写速度”指的就是这个了); 512K:是512K大小数据块的随机读写性能测试; 4K:是4K大小数据块的随机读写性能测试; 4K QD32:是4K大小数据块队列深度为32的随机读写性能测试,QD为Queue Depth的简写。
Test for tampered media that pretend to have more storage area than they physically actually have. Sometimes such media are sold by fraudulent sellers for cheap prices. Measure read and write speed. ... probably lots of other tasks. The random number stream is generated by the following algorit...
Parkdale 3.06 freeware View Image Get the read and write speed from your harddisks, cdrom devices and network servers. You can start a speed test on disks, cdroms and network shares. You get the transfer rate in KB or MB per second. Further you can adjust the blocksize used to access...
Hard drives, though, are typically used for large sequential reads and writes, so a random IO test doesn't match the use case here. If you want to change the test type, you can pass in a different argument for--readwrite.fiosupports a lot of different tests: ...
