How to retain cached data as long as possible

[sanderz]

I have a 1TB NVMe SSD used as cache to accelerate my 8TB HDD, when the data is in the cache driver everything read write is quick and fast, but I noticed PrimoCache peroidically clean or flush the cache (I see it when the unused space got increased), how can I tell PrimoCache hold on to the cached data for as long as possible until my 1TB SSD fills up and overwrite it with more recent cache data? Attached screenshot are my cache configuration:

By default, PrimoCache will not discard cached data until the cache space is full. If the cache space is not full, then only when the source file is deleted will the corresponding cache data be deleted. If you sometimes see L2 cache is empty, you may check the following link.
