What are the egress costs for retrieving large academic datasets from other cloud providers?

Retrieving data from certain academic cloud services can cost $20 per TB or more. This high fee contrasts sharply with the efficient distribution of the 130 TB Pi dataset hosted on Backblaze B2 Cloud Storage.

How much monthly WAN data was consumed during the initial migration to the cloud?

Transferring the full archive consumed 90.9 TB of monthly WAN data during the upload window. This massive volume saturated the uplink while moving the 628 files comprising the complete Pi computation artifact.

What specific file size creates bottlenecks for traditional NAS during concurrent user retrievals?

Metadata contention occurs when handling thousands of concurrent 206 GB retrievals on traditional systems. Object storage avoids this by decoupling data from file hierarchies to store immutable blobs efficiently for global access.

What is the exact confirmed bucket size that exposes physical limits of local storage?

The confirmed 132,210.5 GB bucket size exposes the physical limits of locally mounted storage arrays. Keeping such volumes permanently attached to on-premises hardware proves impractical due to rigid capacity ceilings.

How long did it take to transfer the dataset maintaining a steady 2 Gbps rate?

Moving more than 130 TB of results was completed in under two weeks. The transfer maintained a steady 2 Gbps throughput for much of the process despite bandwidth being the limiting factor.
