What is LD-Writethru?

Answer 1

LD-Writethru is a caching strategy used in computer systems where data is written to both the cache and the backing store (main memory) simultaneously. This approach ensures data consistency and durability, as any changes are immediately reflected in both locations. While it can improve reliability, it may introduce latency due to the need to update multiple storage layers. LD-Writethru is often contrasted with LD-Writeback, where data is first written to the cache and only later to the backing store, potentially enhancing performance.
