Jeff,

Thanks for your recommendation.  I can indeed pipe the output of my 
"data gathering app" to the input of my GPS processor and see if the 
problem goes away.  However, I suspect the problem is not HDD related 
for these reasons:

1. I'm using a 4 disk RAID0 (external eSATA) drive that supposedly can 
handle the throughput

2. When I was disk bound in the past, I would receive USRP overrun 
errors.  I do not receive these errors when I am presently losing a few 
thousand samples out of every 480e6
