OK, thanks for the info. This must be considered.
It turns out that there is no point in using "Free Written" - why clean up the blocks if their contents may soon be needed, and the block update algorithm is able to get rid of old data without clearing them. It's right?

It is indicated by "Deferred Blocks". "Deferred Blocks" means that how many blocks are holding deferred write-data which haven't been written to target volumes. These blocks cannot be replaced and discarded till their deferred write-data are flushed to disks. Other blocks, here almost all blocks (1...
Thank you, sinus. Please note that PrimoCache is a block-level caching program, instead of file-level caching. This means that it caches volumes based on disk sectors, and don't have any information about files. It will cost much CPU time and process to retrieve/trace file information. However, we ...
"if new data need to be cache, PrimoCache will replace some used blocks which store old cache data". - Unfortunately, saving "Urgent" data slows down disk. It would be better to see trends and warn them, for example, by changing the "Latensy" value or playing with other settings of our favorite prog...
"PrimoCache can show basic information about the current use of the cache space by "Free Cache (L1/L2)" - This information is too scarce. She does not give a detailed quantitative representation. To avoid increasing the load for data processing, it would be possible to include an algorithm for analy...
It would be very nice if PrimoCache could display information about the current use of the space allocated for the cache - how much the read data and write data actually occupies, how much irrelevant data is in the cache, which blocks can be replaced at any time by new write data, etc. This would he...

I understood, thank You.Jaga wrote:Yes, TRIM operates on a drive level between Windows and the hardware. PrimoCache operates on a volume level. There is no problem with TRIM commands reaching the drive, it works as expected.

Jaga, You right. But more than 32 Gbytes of RAM can address not all systems. And, forgive for banality, however there will always be non enough memory. Instead of accumulation of memory size it is better to optimize available. Here some compromise is necessary. We like PrimoCache because it helps to...
