The time it takes to upload or download your storage to or from Wasabi depends on several factors, including:
Volume of your storage
Internet speed from your location
Internet speed that Wasabi supports (multiple 10 GB/s connections per data center)
Given the variability of these factors, there is no set answer to the question of upload/download time. Fortunately, many online calculators are available, such as the Omni Calculator or the Expedient File Transfer Time Calculator.
