Globus traces 25-year evolution of GridFTP data transfer protocol

In a retrospective blog post, GridFTP co-creator John Bresnahan describes how the protocol was built in the late 1990s to move massive scientific datasets between geographically distributed instruments, data centers, and visualization facilities. He cites examples like CERN's Large Hadron Collider and Argonne's Advanced Photon Source, which generated multiple petabytes of data monthly, as key drivers behind GridFTP's design, which now underpins the Globus data transfer service.

iOS 27.2 lets developers auto-transfer app data when retiring an old app

Apple's upcoming iOS 27.2 update will introduce a system-managed migration flow that lets developers move a user's data and settings from a discontinued app to its official replacement before deleting the old one. Code found in the first beta shows users will be prompted with an alert offering to 'Move App Data and Settings' or 'Don't Move Anything,' with a follow-up warning if they decline.

External SSDs vs HDDs: speed and durability come at a higher cost per gigabyte

External SSDs use flash storage that speeds up file transfers and editing directly from the drive, while offering greater durability, quieter operation, and lower power draw thanks to having no moving parts. External hard drives remain the cheaper option per gigabyte, with examples like a 2TB Seagate HDD costing less than a 1TB Samsung T9 SSD.
