Meaning
Data storage technology prevents the modification or erasure of information once it has been recorded to the medium. This write once read many setup is for archives where permanence is the priority. It creates an immutable history that can be audited but never corrected.
Compliance Standard
Financial regulations often require that transaction logs are stored on media that cannot be altered. This ensures that an auditor can see the original state of the books without fear that records were hidden after the fact. Storing data in this way fulfills the requirements for electronic recordkeeping in highly regulated sectors.
Hardware Lock
Physical mechanisms in the drive or the optical disk prevent the laser or magnetic head from overwriting existing data. Unlike a software setting that can be bypassed by an administrator, this hardware constraint is permanent. The only way to remove the data is to physically destroy the storage device.
Cost Efficiency
Maintaining a permanent archive requires detailed planning for the volume of data generated. Once a block is written, it cannot be reclaimed, leading to a steady increase in the need for new media. The cost of this storage is a predictable expense for organizations that prioritize the integrity of their history.
A long-term commitment to this technology ensures that the evidence of every founder action is preserved exactly as it occurred.
