Memory crystals: glass storage poised to cut data-centre emissions

Scientists have created memory crystals by laser writing nanostructures inside fused silica glass, enabling five-dimensional data storage that could pack hundreds of terabytes on a 5-inch platter and last essentially forever. The read-out uses an optical microscope, with current write/read speeds around 30 MB/s (targeting 500 MB/s in 3–5 years). If scalable, this could dramatically cut data-centre energy use since data centres consume about 1.5% of global electricity and rising, replacing energy-hungry disks and tapes. DNA storage and borosilicate glass are other long-term contenders, but widespread adoption faces compatibility and cost hurdles; in the near term, improving hardware efficiency and smarter data management remain essential.

Microsoft’s Glass Data Breakthrough Leaves MSFT Shares Largely Unmoved

Microsoft’s Project Silica stores data in borosilicate glass, potentially enabling 10,000-year durability; early tests show 4.8 terabytes on a small glass sample at about 3.13 MB/s write speed. Investors reacted modestly with MSFT stock slipping, though analysts remain bullish with a Strong Buy consensus and a roughly $593 target, suggesting substantial upside despite the current move.

Microsoft's Glass Storage Aims for a 10,000-Year Data Archive

Microsoft's Project Silica demonstrates storing data in laser-etched borosilicate glass via phase-voxel encoding across multiple layers, yielding up to 4.8 terabytes on a 0.08-inch-thick chip. The four-dimensional approach (voxel plus light phase) promises a durable archival medium with a claimed 10,000-year lifespan, addressing the digital dark age by offering a cost-effective, long-term alternative to magnetic media for libraries and archives.

Microsoft's Glass Archive Promises 10,000-Year Data Durability

Microsoft Research has demonstrated a glass-based data-storage system that uses laser-induced nano-explosions to encode information in a borosilicate glass block, storing 4.8 TB in a 12 cm square—roughly 2 million books—with data readable via a microscope. The approach promises near-permanent archival storage, potentially lasting 10,000 years at 290°C and longer at room temperature, offering a more durable alternative to magnetic tapes and hard drives, albeit requiring specialized hardware to write and read.

Glass memory: femtosecond-laser archival storage achieves ultra-dense, millennia-durable data

Microsoft Research’s Silica demonstrates an end-to-end optical archival storage system that writes data into glass using two voxel regimes. Birefringent voxels in fused silica (pseudo-single-pulse) yield 1.59 Gbit/mm^3 density, about 4.84 TB per platter, at 25.6 Mbit/s per beam with 10.1 nJ/bit; phase voxels in borosilicate glass (single-pulse) reach 0.678 Gbit/mm^3, about 2.02 TB per platter, at 18.4 Mbit/s and 8.85 nJ/bit. A multibeam setup attains 65.9 Mbit/s. Data are read with wide-field microscopy and decoded by a CNN-based symbol-inference pipeline plus LDPC error correction, enabling error-free recovery across billions of voxels. Accelerated ageing tests project data lifetimes exceeding 10,000 years at room temperature. The fully automated write/read/decode chain, plus scaling directions (higher NA, more beams, different glasses), position Silica as a durable, high-density archival technology for the digital age.

Microsoft Demonstrates Glass Storage for 10,000-Year Data Durability

Microsoft Research’s Project Silica shows data can be written to borosilicate glass with femtosecond lasers, achieving up to 4.84 TB per 12×12 cm slab and potentially 10,000-year stability at room temperature. Data is encoded and read using voxel-based methods (birefringence or refractive-index changes) plus phase-contrast microscopy interpreted by AI, with LDPC error correction. Current writes run at 66 Mbps with four lasers, expandable to more lasers, but large-scale deployment would require many machines. The approach offers durable, energy-free storage and rapid retrieval, though commercialization remains distant and practical scale remains a challenge.

Laser-etched glass aims to store data for millennia

Microsoft Cambridge researchers refined long-term data storage by encoding data as voxel patterns inside glass with a femtosecond laser. A 12 cm² piece of fused silica (~2 mm thick) can hold about 4.84 TB, read by automated microscopy and ML decoding, with write speed up to 65.9 million bits per second using four synchronized beams. The deformations are predicted to last over 10,000 years at room temperature, though the approach targets cloud-scale use rather than consumer devices due to cost and questions about future access to reading technology.

Discord's age-verification rollout may temporarily store UK selfies for up to 7 days

Discord's global 'teen-by-default' age-verification rollout will require facial age estimation or ID to access certain features; UK users now see FAQ language indicating selfies and identity data may be processed by the Persona age-assurance vendor and stored temporarily for up to seven days before deletion, a shift from the promise that data would never leave the device. Discord says data is blurred and only what's needed is used, but concerns persist about vendor ties and past data breaches as the rollout begins in March.

Revolutionary Magnetic State Promises Next-Gen Data Storage and AI Power

Researchers in Japan have demonstrated that thin films of ruthenium dioxide can exhibit altermagnetism, a new magnetic state that combines the advantages of ferromagnetism and antiferromagnetism, potentially leading to faster, denser, and more reliable data storage technologies. This discovery was achieved by controlling the crystallographic orientation of the material, confirming its intrinsic magnetic properties, and opening new avenues for spintronics and memory device development.
