The ETW buffer size is smaller than the total event size. Once it has reached the limit, the log file automatically overwrites the oldest entries. All versions limit this array to 0x0100 bytes. The ETW buffer size is smaller than the total event size. An example is very fast logging of ETW events in corefx: it has to be as fast as possible and needs very little of memory (so the size limitation is not a problem).
