Data transfer speeds
With a typical network bandwidth of 100 Mbps, one petabyte of data takes about 3 years to upload. However, with Transfer Appliance, you can receive the appliance and capture a petabyte of data in under 25 days. Your data can be accessed in Cloud Storage within another 25 days, all without consuming any outbound network bandwidth.
Refer to the following table to see the approximate upload time for your dataset, based on size and network speed.
Data handling for the European Union
Appliances are shipped from the Netherlands. When data capture is complete, you ship the appliance to Belgium for data upload. Your data is then uploaded to a Cloud Storage staging location in the region you chose as the final destination for your data when you signed up for the appliance. If you choose a destination region within the EU, your data never leaves the boundaries of the European Union during any part of the data transfer process.
