The setting seems no problem. If your RAM is sufficient for other applications, you can increase L1 cache size.

Yes, this issue will be addressed.

The new version was supposed to be released this month, but there was a delay in the development progress and it was postponed to this quarter. Sorry.

I think the root-cause is that at the moment the file was written, it's already in the memory cache of windows. Reading the file immediately after it's written touches only the memory cache and thus no request to the storage space is sent. Yes, this is correct. This is indeed a problem for which th...

So far PrimoCache cannot support to cache random or small files only. It caches all files. So I think it's not good to use one SSD to cache another SSD. You can use RAM as cache for these SSDs if your RAM is sufficient.

I'm really sorry I forgot to update the progress here. We have confirmed this issue. It will be fixed in the next version along with other fixes. Thank you.

In fact, I think this is reflecting that L1 prefetching only works for L1 "read" cache, am I correct? If it is true, can we add this notice to the Configuration Terms page of the PrimoCache help documents? Correct. We have updated the help document. You may refresh the page to see the lat...

I just noticed that this thread has no replies. Sorry I forgot to reply. RAM cache still can help as RAM is much faster than the nvme SSD and it has no write wear. However you may not see noticeable difference if your drives are not heavily used in your scenario. If your drives have lots of access, ...

I set a Read/Write L1 and L2 for both the external SSDs and HDDs and now everythings speedy. I'm glad to hear PrimoCache helps. :) I assume a file first being downloaded to the SSDs will store in the cache and then when its moved later to the HDDs utilize that cache for the transfer? Yes, as long a...

Because defer-write is enabled, write-data will be first stored in the cache (here the L1 cache, according to your configuration) and then flushed to the target drive (D:) at a certain interval (here 10s), that's why you saw intermittent writes on the D: drive. PS. Your L2 cache is too small (only 6...
