TDMS Asynch Writes is "max write size" per channel or is example wrong?

[D*]

In this NI example, it shows how to use asynch writes.

In #4, the buffers are preallocated at 64 samples. However, each write actually uses 128 samples (see the array size from the For Loop).  Shouldn't the buffers be preallocated to 128 samples?  Or should the documentation say that the "max writes" are per channel? (Doesn't seem to throw an error if you have this preallocation number off, but I would expect performance to suffer?)

Yes, you are right, there is something wrong with the example:

1. The file size to reserve should be 128*8 

2. The buffers of Configure Asynchronous Write should be preallocated to 128 samples.

Thanks for pointing this out and I have reported this issue to NI.

It appears as though this has not been fixed in LabVIEW 2013 and also occurs in other examples:
