Simulink to workspace conversion

In simulink, a random signal is applied to a plant model. I wish to have the input data and output data in workspace. I used 'To workspace' block. when I used save format as 'time series' both gave me just one data. When I used 'array', the input is 1000 data and output is 6001. How I can get Input and Output array of same size sampled at the same instant?

In the "to workspace" bloc set the sample time to the same value
