ATTO Technology Inc. FastStream SC Installation and Operation Manual
 6.2  Drive Diagnostics
You may determine the performance of drives attached to the FastStream using various displays and tests in 
ExpressNAV Storage Manager. 
The following instructions assume you have already 
set up at least one RAID group. 
The ATTO FastStream collects various metrics to 
measure performance for physical drives attached to 
the FastStream during normal system operation and 
drive initialization and verification.
New performance data is updated every 60 seconds 
which impacts performance slightly, even if you 
minimize the browser window. Exit the ExpressNAV 
Storage Manager completely whenever you need 
maximum performance.
