USRP's cfile utility cannot write my data without overruns, so I use
my own app which I have attached to this email in case anyone is

FWIW (maybe you've fixed the problem already), I would think that if
this is the case then you're using the cfile script wrong. Are you using
the '-s' switch (to halve the required disk bandwidth)?
Hi Dan,
Yes, I record the data as 16 bit shorts vs. 32 bit floats. At 4Msps
complex data, this provides 16 megabytes per second which is within the
capabilities of my 4 disk RAID0 array. Here are the results of the
bonnie++ benchmark which reports my drive can write at 58 megabytes per
second:
