How Much X-ray and Gamma-ray Data Are Coming In and Going Out of the HEASARC Archive Every Day?
Last Update: 2017 February 14
As of this date, the HEASARC's high-energy archive is growing about 24 Gigabytes (GB) every day, equivalent to 10 Terabytes (TB) every year.
HEASARC users are downloading about 420 GB/day of X-ray and gamma-ray data, equivalent to about 155 TB/year. This can be compared with the current 85 TB size of the entire HEASARC High-Energy Archive. Thus, in one year the HEASARC user community downloads a data volume 1.8 times the size of the archive.
