Electronic anti-shock cache/retro cache

I've finally made the plunge and ordered 3 FS-4....got a question. What are the differences between/or funtions of the two cache features

The anti-shock cache, acts as a data buffer, so that when the HDD is not able to write data to disc because of a mechanical jolt, the data is not lost. The video data is stored in a (I'm assuming RAM-like) buffer and is written to disc after the HDD has recovered from the disruption. Data loss occurs when the duration of the disruption is longer than the buffer length (cache size).

The Retro cache is a function in which the FS-4 constantly records and re-records over a set block of memory, before and up until the record trigger on the camera is pressed, at which point the FS-4 starts recording linearly. This is good for people who are waiting for something to happen, like a bird leaving a nest or a speaker to enter a room. The FS-4 does not fill the HDD with unwanted video data because it re-records over the same memory.

I hope that that makes sense.
