Blu-ray storage

Optical storage, challenging data storage for a hundred years

Traditional storage media adopt the principles of magnetic storage and electrical storage. As there are no “permanent magnets” and “permanent electret”, data cannot be securely and stably stored for long-term. Storage server devices need to be replaced every 5 years or so.

Optical storage merits

Long life, high reliability, low cost, green and environmental protection

01

Long service life

The principle of optical storage technology is physical recording. Due to the long-term stability of inorganic alloys, it is not easy to decompose.

Therefore, the data can be stored safely and stably for more than 50 years to 100 years

02

Safe and reliable

It has the characteristics of one-time write and cannot be tampered with, which can fundamentally solve the problem of data storage security.

03

Low cost

Mass data is prone to data loss during the migration process of new and old equipment, and repeated purchases increase costs

The optical storage data does not need to be migrated, and it is stored for a long time for 50 years.

04

Low power consumption

After 50 years of long-term storage of data, the overall power consumption is only 1/10 of that of disk storage, which significantly reduces IDC energy consumption.
