Unfortunately, I don't know the record size of the writes. Is it as simple as looking @ the size of a file, before and after a client request, and noting the difference in size? This is binary data, so I don't know if that makes a difference, but the average write size is a lot smaller than the file size.
Should the recordsize be in place BEFORE data is written to the file system, or can it be changed after the fact? I might try a bunch of different settings for trial and error. The I/O is actually done by RRD4J, which is a round-robin database library. It is a Java version of 'rrdtool' which saves data into a binary format, but also "cleans up" the data according to its age, saving less of the older data as time goes on.
