Writing from USB to Disk continuously....

Hello,

Our device streams data over USB at about 27MB/sec to a mac computer. Our software on the mac then displays the data, and if the user presses the record button, records it to disk.

I was wondering if anybody had any insight as to how to correctly do this, or streamline the process from what we are doing right now:

We are initially sending 4 async USB read calls, each one with its own buffer. The call back function for each read calls another function which displays the data, and if the record variable is set, writes it to disk using fwrite(). It basically works as a circular buffer.

Should we be using fwrite() at all? Is this the correct overall approach to doing this?

Since we are writing a large amount of data, it seems like it would be great to have an async version of disk writing functions for this purpose.

Cheers,
Juan
