write-once storage

Medium Limitation

Storage drives designed for immutable writing cannot be repurposed once their capacity is exhausted, requiring physical replacement. Using write-once storage demands that organizations carefully plan their capacity based on expected data ingestion rates. The upfront cost of these physical drives is higher than standard read-write media, but they provide absolute data durability.

Retention Policy

Corporate policy must dictate which specific logs are routed to this permanent medium to manage storage costs. By sending only the essential audit trails and transaction summaries to write-once storage, the company optimizes its infrastructure budget. This focused approach ensures that the most critical evidence is preserved without overwhelming the available system capacity.

Dispute Resolution

Having an unalterable history of transaction events provides definitive proof during legal and contractual conflicts. When a dispute arises, the records retrieved from write-once storage are accepted as authentic because they could not have been manipulated after the fact. This evidentiary value can save a company millions of dollars in legal fees and settlement costs by quickly resolving claims of unauthorized modifications.

It represents the ultimate technical defense against internal fraud or external record tampering.
