data storage

Researchers report a technique for reshaping light to control magnetic memory and adjust a material's magnetic properties. The advance could point toward faster, more efficient data storage, since it suggests magnetism in certain materials can be manipulated optically rather than only with electric currents or magnetic fields. Details of the method and its practical applications have not been widely reported yet.

A new report argues the next wave of American battery demand will come not from electric vehicles but from grid-scale storage, as utilities add batteries to balance growing amounts of wind and solar power and to stabilize an aging electricity network under rising demand from data centers. Industry watchers see this as a structural shift in where battery manufacturing and investment will flow next.

A cross-tenant data exposure flaw in Cloudflare's Containers and Sandboxes has been disclosed and fixed. The issue stemmed from dm-thin storage pools running with skip_block_zeroing enabled, meaning newly written 4 KiB pages into unmapped 64 KiB blocks could leave residual data on raw devices. A Workers Paid tenant could reportedly read up to 60 KiB of data left behind by a previous tenant from /dev/vdc. Cloudflare has patched the issue, and security communities are discussing the implications of shared-storage isolation failures in multi-tenant cloud platforms.

Seagate Technology Holdings is drawing investor attention as demand for data storage rises on the back of artificial intelligence workloads. A market commentary asks whether the hard drive maker's stock, which has benefited from this AI-driven storage demand, remains undervalued at current prices. Analysts and investors are weighing Seagate's growth prospects against its valuation as AI infrastructure spending accelerates across the technology sector.

Romanian engineering company Dai-Tech expects solar power, energy storage and data centre projects to account for more than 65% of its turnover by 2027, the company said in an interview with SeeNews. The outlook points to a strategic shift toward energy infrastructure serving growing power demand, including from data hubs.

A researcher is analysing how battery storage capacity in Germany is developing, using raw data from the Bundesnetzagentur's Marktstammdatenregister. The work, shared with the Steady Klimacrew community, applies the same data-driven approach previously used to track the growth of balcony solar installations, aiming to show concrete trends in the rollout of stationary electricity storage.

Claims are circulating that deleted photos on Windows leave recoverable previews in the thumbnail cache, and the rumor has drawn attention to how the operating system stores image previews even after files are removed. Guides are being shared explaining how to clear the cache using Disk Cleanup or Storage settings. Privacy-focused users are debating whether Microsoft should make this clearer.

Backblaze has published its quarterly drive reliability report covering the second quarter of 2026, detailing annualized failure rates across the hard drives in its cloud storage fleet. The report is a regular fixture for anyone tracking which drive models hold up best over time, and the latest edition drew a large, engaged audience on Hacker News as readers compared model reliability and annualized failure figures.

A question circulating among developers asks whether AI agents should be granted access to cloud-hosted files under a least-privilege security model, meaning each agent gets only the minimum permissions needed for its task. The discussion touches on how to sandbox autonomous software, audit its actions, and prevent data leaks as more teams let agents read and write to production storage.

Orbital data centers, the idea of placing computing and data storage infrastructure in space, are drawing attention as a possible next step beyond terrestrial cloud facilities. The concept promises abundant solar power and natural cooling, but raises questions about launch costs, latency, radiation and space debris. Space policy watchers are debating whether orbit could realistically host large-scale compute.

Officials in Winnebago County, Iowa, are drafting a new ordinance to regulate solar energy installations, cryptocurrency mining operations, battery storage facilities and data centers. The measure would set local standards as demand grows for large-scale energy and digital infrastructure projects in rural Iowa. Local radio reports say county leaders are moving to get rules in place before such developments arrive.

Open Source For You examines infrastructure processing units (IPUs), describing them as the unsung heroes of the modern data centre. The technology article explains how these dedicated processors offload networking, storage and security tasks from main CPUs, freeing them for application workloads as data centres scale and traffic grows.

NetApp has agreed to discover and resell Diskover, a data management product aimed at helping organisations find and deal with ROT data — redundant, obsolete or trivial files that clog storage and raise costs. The deal, reported by storage industry outlet Blocks & Files, adds file analytics and cleanup capabilities to NetApp's portfolio, letting customers identify stale data across their environments and delete or tier it rather than keep paying to store it.

Researchers suggest that the key to improving magnetic memory may lie in how light is used rather than in the magnetic material itself. The finding could point to new ways of designing faster, more efficient data storage by tuning light-based control of magnetism, drawing attention across the physics and materials science communities.

A technology educator has shared a walkthrough of the main components found inside a data center rack, explaining what each part does. The breakdown covers standard hardware such as servers, switches, storage and power distribution, and is aimed at readers wanting a plain-language primer on data center infrastructure. It is being shared alongside free downloadable infographics and ebooks on computing topics, drawing attention from people interested in hardware and IT basics.

A cybersecurity writer is promoting a layered privacy setup for 2026 that combines encrypted email, a no-logs VPN, DNS filtering and encrypted cloud storage. The idea is that each layer covers for the others, so no single leak exposes a user's data. The guide is circulating among privacy and infosec audiences.

Microsoft is positioning Fabric as a single, unified data and AI platform, marking a strategic shift in how enterprises manage analytics and artificial intelligence workloads. The pivot brings data storage, integration, analytics and AI tools together in one product, as businesses increasingly seek end-to-end platforms for building AI applications on their own corporate data.
