Is there a risk of data loss without Defer-Write enabled?

PrimoCache can accelerate disk reading and writing. For read caching, the data in the cache is just a copy of the disk data. Therefore, in the case of sudden power failure, system crash, etc., the loss of cache data will not cause the loss of disk data.

For write caching, if Defer-Write is not enabled, data sent to disk by Windows systems and applications will be directly written to disk. In this case, PrimoCache introduces no additional risk of data loss. Of course, correspondingly, the write performance will not be improved.

Only when Defer-Write is turned on, there is a risk of data loss on ungraceful shutdowns due to sudden power failure, system freeze or crash, etc.
