The following chart is an approximation of OTA recording storage usage for onboard storage on a 4th Generation Tablo vs. a 1TB external hard drive.

  Average Bandwidth Average Gigabytes/Hour (OTA)
Onboard Storage 3 Mbps 1.35 GB/hr
External Storage (1TB) 9 Mbps 4.05 GB/hr

 

This next chart is an approximation of free streaming recordings storage usage. This is identical for onboard and external storage on the 4th Generation Tablo models. Bandwidth varies as free streaming channels are delivered at a bit rate that adapts to your external internet speed to avoid buffering. 

  Average Bandwidth Average Gigabytes/Hour
Onboard OR External Storage .5 Mbps – 5 Mbps 2.0GB/hr
