I think I noticed one benefit, when writing a large file - 8 Gb, if it starts flushing during the copy, it rewrites to those freed blocks as they free and evicts a lot less of already cached data. I wrote an 8 Gb file to a full L1 cache and I found that the free cache after copy complete was 2.5 Gb....

Ok, thanks. 2 more questions. 1. Is there an overall benefit to this setting? 2. Why would the free cache value increase after the blocks are written? Is it just that the equation for free cache excludes the standby blocks?

I notice that if I have the option to "free cache on written selected", after data is written, whether cache is full or not, the free cache value increases. Are the blocks still cached (as standby blocks) but just not accounted for in the number? The change in the number has confused me wh...

FYI, I did install Windows 10 and the problem no longer exists even with the drive as fragmented as it is. Win 10 writes it all very smoothly.

I did further testing on this. The problem is not PrimoCache. The problem is Windows. With PrimoCache not running, Windows Modified Memory gets badly bottlenecked because it seems it does not handle large files well if they are being copied to an external hard drive if there is quite a bit of fragme...

Hi, ever since I started using PrimoCache many years ago I have always experienced problems when writing to external hard drives when the L1 and L2 flush to disk slows right down to only a few blocks per second and the entire system does not respond well caused by this very slow flushing of cache on...

Just compress the files/folders on your spinner. That is what I do. Since PrimoCache works at the block level, the data in L1 and L2 will be compressed. This way you can get on average an extra 50% out of L1 and L2. An important item to consider is that compression is subject to significant fragment...

Thanks. I should have been more clear on question 2. I meant file read performance. Does Instant Gather slow down read performance at all from the hard drive if data is not in L2 since it will instantaneously read HDD and write to L2.

1. Does L2 Gather gather the data in an optimized way e.g. gathers data in sequential order according to cluster number? 2. Does Instant gather setting in any way interfere with file access if the drive is accessing data from the hard drive or is the data just written to L2 immediately as it is acce...

Can I ask a variation on this question? Let us say I have L1 50% R/W. If there is L1 Write data that gets read a few times and becomes hot. Does that now become counted so that it changes Free L1 read cache does it remain in L1 write? In other words, assume it is 1 Gb, when it is read and becomes ho...
