Chinese researchers are investigating the potential of organic materials to develop a new type of hard drive that can potentially store six times the amount of data compared to current mechanical models.
Traditional hard drives store data in binary form that depend on magnetized regions to represent them and zeros, which limits storage capacity. Molecular hard drives overcome this by using self -mounted monol layer of organometallic complex molecules such as ruXLPH, to increase data density significantly, while maintaining ultra-low power consumption, measured at only 2.94 picowatts per day. Bit.
A key component in the operation of molecular HDDs is the leading nuclear microscope tip (C-AFM) that acts as the mechanical programming and reading head. TipXLPH molecules. The tip’s nano -scale solution allows precise control over molecular wiring states, allowing the storage of multiple bites in an unusually small footprint.
Encryption at molecularly level
Another advantage of molecular hard drives is the improved safety they offer. Unlike traditional drives that require separate encryption mechanisms, molecular HDDs have in-situ Xor encryption at molecular level. This capacity allows secure data coding and fetching without additional hardware, reducing vulnerability to cyber threats.
The researchers demonstrated this by code and encrypt a 128×128 pixel image, proving the system’s ability to safely store and retrieve data.
The research was published in Nature Communication. The authors say that future work will focus on improving miniaturization, increasing wiring states and tackling environmental sensitivity.
Blocks and files However, make an interesting point. “Working life for a nuclear power microscope tip is currently measured in 50-200 hours in intermittent touch (TAPE) mode against 5-50 hours in continuous touch mode. Unless and up to a long-lasting C-AFM peak can be created, it seems to be a deadly error in their molecular hard drive concept. Another point is that the device has “Ultralow power consumption in PW/BIT range”, but this is for reading and writing, not spinning the disk, which would take more power. “
