benchmarkinghard drivemacosreal time
I am looking for a program/app that will show me the current data rate that is being written and/or read from the hard drive in real time, for the Mac.
I want to see the rate at which the hard drive is reading/writing when I'm rendering video files in After Effects and Final Cut.
Is there a program to do such a task??
What you are looking for is Process Explorer. Go to "View" -> "Select Columns" then select the tab "Process Performance" and select what you want to know:
It looks something like that:
You might want to have a look at badblocks(8), a command-line tool from GNU/Linux. There is a port for Darwin, which you can get from MacPorts:
sudo port -v install e2fsprogs
Having a look at the manual, you can read the -n and -w options' paragraphs:
-n Use non-destructive read-write mode. By default only a non-destructive read-only test is done. This option must not be combined with the -w option, as they are mutually exclusive.
-w Use write-mode test. With this option, badblocks scans for bad blocks by writing some patterns (0xaa, 0x55, 0xff, 0x00) on every block of the device, reading every block and comparing the contents. This option may not be combined with the -n option, as they are mutually exclusive.
Hopefully this is what you are looking for.

Have you tried iStats Menu? No longer free but it has a disk activity module.
