Re: L2 Cache Cleared on Reboot

I wonder if this is an order-of-operations issue.

I could see a world where Storage Spaces are initialized after the PrimoCache driver and therefore the driver can't see the partition it's expecting at startup and marks the cache dirty or something similar.

Re: minimum frequency at which blocks are allowed to be cached into level-2 storage

for exampe HDD speed is around 100 MBps, HDD IOps is around 100. that means no need to cache read operations greater than 1 MB. or 2 MB depending of certain disk
This doesn't really make sense to me. Even if the file is only 1MB it will be faster to read off of an SSD or NVMe.

Re: License policy question

I can independently confirm that Romex Support has been very helpful and accommodating with license refresh requests. I believe that as long as you are not taking advantage of their good-will they will be happy to help you via email.

Re: License policy question

I have requested a license refresh in the past without issue. In practice I do not believe you will have any problem - I'm like you, gamer, frequent hardware upgrades - and the worst you'll experience is needing to email their support folks :)

Re: L1 Cash does not work

Hello fsdejkncv

Please post screenshots of your Cache configuration; both the main window, and the cache task settings.

Have you tried deleting and recreating the cache task?
What are you system details?

Re: RAM + Optane as cache for SSD

Not sure what you mean by "can PrimoCache handle it" but I'm gonna say yes. There is nothing you described that PrimoCache wouldn't be able to handle. I'm skeptical of the practical performance increase you'll see running a good NVMe SSD w/ Optane cache, but there's nothing stopping you from doing i...

Re: 1Tb SSD Level 2 cache for gaming?

Very cool! Thank you for the answer. I have close to 1TB of data that is mostly large files, and usually requests are large sequential reads. I should have set a larger cluster size when creating the partition but it is 4kb (windows default). I'm procrastinating on backing up the data, changing the ...

Re: HDD will lose speed when L2 Cache is full

Very interesting test results! Thank you for sharing. I think @support will have a better answer than me :) A guess: when cache is full, there is latency added because instead of doing this... (Read Source -> Write Cache) -> (Read Cache -> Write Target) ...It has to do this... Read Source -> Wait fo...

Re: 1Tb SSD Level 2 cache for gaming?

Side question for @support: If the L2 Cache block size is larger than the target volume's cluster size, will files above the volume's cluster size be aggregated into the larger block size in the cache? e.g.: Target Volume Cluster Size: 4KB Cache Block Size: 64KB File size: 2,048KB Question: Will eac...

Re: HDD will lose speed when L2 Cache is full

It sounds like what you're asking for is: - Deferred Write while the cache has free space remaining - Effectively, writethrough once the cache is full (such that the data hitting the HDD is always FIFO through the cache) I believe this is how it already works. How did you confirm that "the reason th...
