Information type
Amount of data
(MB/day)
Status information from SAM/MEG: 1.31 (including GCF header)
Seismic data:
3 channels x 2 systems x (100 + 20 sps) x 2 bytes (typical) x 3600 s x 24 hr + header 121
Slow seismic data:
4 channels (mass, position, and temperature) x 2 systems x 4 sps x 1 byte x 3600 s x 24 hr 2.68
Total:
186 days to fill 22.8-GB (5712 MB x 3 + 6176 MB x 1) hard disk storage in the SAM-195 125

Notes: SAM = storage acquisition module, MEG = multiple-access expandable gateway. GCF = guralp compressed format. sps = samples per second.
