The total size of raw data files stored on disk during operation depends on several user selections. From these selections you may estimate approximately the total amount of raw data stored in a given time period for each installed
channel. Use the following equations:
X = ([#SB*4] +[#B*2]*[Range] * [SampleDistance]
X = Total amount of stored raw data in bytes for a single ping
#SB = number of split-beams in selected beam mode
#B = number of single beams in selected beam mode
Range = Depth range in meters
X = Sample distance, can be obtained in the Numerical information field or in Extra menu
Note that additional datagrams will add to the total, but these are significantly smaller than the size of the raw data.
If you wish to calculate the amount of data stored for a given period of time, you must add this equation:
T=X*PRF*60*24
Where:
T = Total amount of stored raw data from 24 hours of recording
X = Total amount of stored raw data in bytes for a single ping
PRF = Pulse repetition frequency (number of pulses per minute)
