Writing to MicroBooNE disk rate¶
The NU stream rate is reduced by the PMT triggering by a factor of 70. In addition, it is Hoffman compressed , which reduced the data by a factor of 5.
Thus, at MicroBooNE’s maximum 15 Hz beam spill rate. MicroBooNE expects a total triggered write rate of around 12 MB/s.
The SN stream circular buffers, which are aggressively (non-losslessly) compressed beyond what the NU stream experiences, fill each one of the SEBs 14 TB in on the order of one day, which is ample time to respond to a SNEWS alert.
