I don’t ever recall anyone saying they get overwritten after 28 days 
But It can be upto to a year’s worth on them.
It’s all down to the working pattern you have. If you go out and do a night trunk each night, then you will fit more data onto the card than a 7.5t multi-dropper. Thats because your work will create ten or so entries each way, while the MultiMan could be putting in hundreds of entries a day.
The card will store a MINIMUM of 28 days data.
