5d storage technology can fit 500tb on a small disc

While most consumers today are perfectly satisfied with the capacity and reliability of modern solid-state drives (SSDs), various organizations that are required to archive massive quantities of data are deeply aware of the limitations of not just SSDs but other currently available storage technologies as well.

Soon, they might be able to store up to 500TB of data on a CD-sized disc thanks to a new energy-efficient laser-writing method for producing high-density nanostructures in silica glass. Called five-dimensional (5D) optical data storage, this method could theoretically be used to archive data for as long as 13.8 billion years, and the optical discs produced by it can survive temperatures as high as 1,000 degrees Celsius.

“With the current system, we have the ability to preserve terabytes of data, which could be used, for example, to preserve information from a person’s DNA,” said Peter G. Kazansky, leader of the research team behind the new data storage technology.

5D optical data storage isn’t actually an entirely new invention, but its practical applications were greatly limited in the past because of its slow write speed. To improve it, the research team from the University of Southampton in the UK used a femtosecond laser to produce an optical phenomenon known as near-field enhancement, minimizing the thermal damage that prevented earlier researchers from making 5D optical data storage truly usable.

“This new approach improves the data writing speed to a practical level, so we can write tens of gigabytes of data in a reasonable time,” said doctoral researcher Yuhao Lei. By a reasonable time, Lei means about 100 pages of text (roughly 230 kilobytes of data) per second.

When you compare that figure to the writing speeds of modern SSDs (anywhere from 200 megabytes per second to 4,000 megabytes per second), it becomes apparent that regular consumers won’t be replacing their storage drives with it anytime soon.

lebanon ministers meet visa over national digital payment platform

Lebanon’s finance and technology ministers met representatives from Visa last week to discuss a proposed unified national digital payment platform for government services, according to a readout from the Ministry of Finance.

The meeting brought together Finance Minister Yassin Jaber, Minister of State for Technology and Artificial Intelligence Kamal Shehadeh, a Visa delegation, and experts from both ministries. Discussion focused on whether Lebanon could establish a single platform through which citizens and institutions would pay taxes, fees, fines and other official transactions electronically, using mobile phones and other digital channels.

The Visa delegation presented examples from countries that have adopted unified government payment platforms, including the United Arab Emirates, Singapore, Estonia and Jordan. According to the readout, the examples were presented as having increased collection rates and expanded financial inclusion.

Talks covered settlement mechanisms, direct transfer to the treasury account, financial reconciliation, risk management, cybersecurity, fees, and an operational model that would involve the private sector. The parties agreed to continue technical and institutional consultations, prepare a comparative study, and develop an implementation roadmap before any decision on adopting a model for Lebanon.

Jaber said the Ministry of Finance had already enabled citizens to pay using credit cards and e-wallets through transfer companies, but described the proposed platform as a further step. He framed the development of electronic payment and collection systems as a priority within the ministry’s modernization plan.

Shehadeh outlined the citizen-facing concept as a single mobile application through which users could settle obligations to ministries, government institutions and other bodies.

“The idea, in short, is that any citizen downloads an application on their mobile phone, through which they can pay all service obligations for all ministries, government institutions, or those owned by the Lebanese state, and others as well, as the platform is not limited only to state institutions,” he said.

Shehadeh added that the platform would not displace banks and money transfer companies that currently provide collection services to the state, calling it complementary to their work.
