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...

PrimoCache will log an event when it is unable to obtain the required amount of RAM. Could you follow the guidance in the link below to check if there are any events with source "FancyCcV"? If there are, please export these events and send them to support@romexsoftware.com. Also please fol...

Is there any benefit to using a L2 external NVME for both read and writing? I don't see how writing would benefit speed as the files already go from one of my SSDs to a HDD and the HDDs don't really swap files between themselves. The HDD drive speed being the rate limited step. Do you mean using an...

Do you use the "Average" write-mode? Can you upload a screenshot of the PrimoCache main dialog as described in the link below?
