- Reading the Results
NOTE: The goal is to have the Target values be as close as possible to the Actual Values.
1. Target Values are slightly higher than Actual Values -
- The hard drive(s) could possibly be having issues handling the amount of data being written.
2. Target Values are roughly 50% higher than Actual Values -
- The issue could reside in network storage issues or bottlenecking on the network.
3. Target Values are roughly 75% higher than Actual Values -
- The storage drive(s) are possibly failing or could fail soon. Files or folders could be corrupt or no longer readable.
