What tape technology is being used for comparison?
For calculation of the tape solution, an LTO-2 configuration is used. The average throughput rate used in this model is 25 MB/s. This reflects an industry observed average and not the best-case or worst-case rates possible. The capacity of LTO-2 is 250 GB/tape. This represents a combination of 200 GB base capacity (no compression) with 1.6x data compression and 80% utilization rate approximations. The exact number of tape drives and media can vary based on several other infrastructure and data type considerations.
