Testing Linux Disk Read Speed over SSH

Server performance depends on the processor, RAM, operating system and storage. The original article highlights disk performance as an important factor.

To test disk read speed on Linux, the source connects over SSH and runs:

hdparm -t /dev/sda1

/dev/sda1:
Timing buffered disk reads: 500 MB in 0.75 seconds = 669.63 MB/sec

The example reports a buffered read speed of approximately 669 MB per second. This is the original sample output, not a benchmark of your server.
