Performance Chart
The Performance chart provides two different real time performance metrics:
transfer speed MB/s (megabytes per second) and transfer IOPS (I/O operation
count per second).
The chart scrolls from right to left and shows moving, 5-minute time line increments
on the horizontal axis. The vertical axis of the chart will show either Transfer Speed
MB/s or Transfer IOPS.
Transfer Speed MB/s
The SSD MB/s write and read speeds are shown in the chart with blue and green
indicators, respectively.
Transfer IOPS
The SSD I/O write and read speeds are shown in the chart with purple and red
indicators, respectively.
