How to Assess Disk Performance Using mongoperf

MongoDB comes with a free disk performance assessment tool named mongoperf that can be run independently without MongoDB.

1) Copy the contents of MongoDB’s /bin folder onto to the disk whose performance you want to assess

2) Then run it with the following command (the config file mongoperf.conf.js is available here)

mongoperf < D:\temp\mongoperf.conf.js

40 MB/sec or better can be considered good.
