One of the most often asked questions is how much storage do I need for N minutes of capture @ X Gbps? Or the inverse of how many Minutes of X Gbps capture does can the capture system hold? We have condensed this into some easy to read charts.
Lets start off with full line rate capture. While very few customers need sustained full line rate of extended periods of time it provides a good reference benchmark to go by.

NOTE: The numbers are slightly inflated, as we`ve assumed every month has 31 days to keep the simplify the calcuation
Conclusion
Even at sustained 100Gbps running 24/7 our high end storage option for the 1U 100Gbps capture system has the SSD endurance for almost 2 full years ( ~800PB ). While the absolute numbers are some what crazy sounding, Enterprise SSD endurnace has come a long way over the past few years!
