Quantum Holographic Storage System HoloStore Launches: Single Disk Capacity Hits 100PB With 10,000-Year Data Lifespan

On July 25, 2028, Microsoft Research and the Huazhong University of Science and Technology's Wuhan National Laboratory for Optoelectronics jointly released the HoloStore quantum holographic storage system. The device, roughly the size of a small refrigerator, can store 100PB of data in quantum holographic form within a lithium niobate crystal, with a theoretical preservation lifespan exceeding 10,000 years.

HoloStore's technical principle is based on a quantum-enhanced version of three-dimensional holographic storage. Traditional holographic storage records interference patterns on two-dimensional planes inside crystals, while HoloStore uses quantum entangled photon pairs to encode information in quantum states throughout the crystal's three-dimensional volume. Each storage unit shrinks to approximately 50 nanometers— one-thousandth the size of conventional optical storage.

Douglas Burger, head of storage technology at Microsoft Research, said at the launch: "Global data volume doubles every two years, but storage technology density growth can't keep pace. HoloStore isn't an incremental improvement—it's an entirely new storage paradigm."

The system's main bottleneck is read/write speed. HoloStore writes at approximately 2GB/s and reads at about 5GB/s—far below SSD levels but above tape storage. Microsoft says the initial application scenario is cold data archiving—data that is written once but rarely accessed yet needs long-term preservation, such as genomic data, satellite remote sensing data, and cultural heritage digitization archives.

A single HoloStore unit costs approximately $2.8 million, expected to drop below $800,000 by end of 2029. Microsoft has signed initial procurement agreements with the US National Archives and CERN. The Huazhong University team is responsible for core crystal material fabrication and has filed 23 international patents.
