Living in the digital age, cloud technology has brought great influence to our daily life and work. However, cloud technology still needs to be linked to physical reality and limited by physical storage solutions. That is to say, the cloud storage services you use to collaborate and store will eventually be stored in an old but mature technology like hard disk. Microsoft researchers are working on an old and innovative idea of using holograms to store data in a smaller physical space. < p > < p > holographic storage is not a new concept, but it is about to become a reality. The ubiquitous cloud storage has created a special demand for hot storage, which allows people to access data quickly, and a large amount of data is too expensive for flash memory. That’s why hard disks and disks of mechanical components are inherently slow, but they are still the preferred storage for cloud storage and services. < p > < p > and holographic storage has the potential to solve all these problems and may bring additional benefits to this particular use case. Holographic storage can simply change the angle of light irradiation on the crystal, and a large amount of data can be crammed into a small area of crystal. Unlike Microsoft Research’s project silicon, which is based on light, holographic storage data (HSD) can be erased by ultraviolet light, so it can be rewritten like a mechanical or solid-state drive. < / P > < p > although the crystal of holographic storage can be very small, the equipment needed to read and write them is not small. However, although this is a stumbling block for consumer devices, cloud storage already uses large racks to store hard disks, so this is not a big problem. In fact, HSD devices may become more compact, allowing data storage manufacturers to cram more capacity into the same space as a normal rack. < / P > < p > of course, these are almost all in the research phase, so it is unlikely to completely change cloud storage in a short period of time. Microsoft research has a lot of work to do, such as improving data access without mechanical movement, but it believes that Microsoft’s expertise in artificial intelligence can help push this process forward. It is said that “gta5” will be launched on Google cloud game platform stadia
