Excessive write killing hard drives #5

In some configurations of the code, the data-write to disk can be 360GB/hour (e.g. when streaming DC-25MHz raw IQ). Given typical SSD terabyte write (TBW) limits of around 100 - 3000 TBW, we might expect disk failure within a few weeks to a year.

I think the short term fix is a health warning and the long-term fix is an implementation that performs all processing on IQ stored in memory. This will likely require ~64 GB RAM or so (just for the IQ buffer), given the longest chirp is ~200 s and we probably need some buffer around it.
