Re: HDD will lose speed when L2 Cache is full

@Cheung, welcome to the forum! For your question, even when cache space is full, source disk will not directly write data to the target disk. It will wait until cache space has room available. The workflow is just as neatchee said. It is not easy to get a very good acceleration if your incoming writ...

Re: 1Tb SSD Level 2 cache for gaming?

When populating L2 cache, PrimoCache will fetch the whole block data from the target volume. This design is to maximum utilize L2 cache space. So, Question: Will each cache block contain 16 target volume clusters? And will a request for all 16 clusters be returned from the cache as a single read ope...

Re: 1Tb SSD Level 2 cache for gaming?

@Verdin, regarding the block size, when it matches the target volume's file system cluster size, caching will have the best read performance. However, if the block size is too small, it may cause lots of memory overhead which is used for maintaining the cache task. PrimoCache will show the estimated...

Re: Optane caching setup

Generally, larger cache size, better performance. Because large cache space will reduce the occurrence of caching replacement. In your case, for HDD caching, if you have multiple spare SSDs, you may group them as a large dynamic disk and use it as level-2 cache for HDD. And regarding the block size,...

Re: [Feature request] Hybrid Write

cichy45, thank you for your suggestion!
This is still a kind of defer-write. And please note that Windows default write behavior is also a kind of defer-write, with 2 second latency.
I think the key point here is to support data restore after power loss. We are working on it.

Re: Event 129 secnvme

I suspect this issue is caused by multiple factors together: Windows, motherboard chipset, and hard drive. They are all involved in the power management. However, as far as I know, this issue mostly happened in Samsung SSDs. Maybe their firmware cannot handle it in good manner. Anyway, neatchee, tha...

Re: Optane caching setup

I think there is no need to use 400GB (intel 750) ssd to speed up 905P. If I remember correctly, 905P also uses m.2 pcie nvme and it shall be a little faster than intel 750. Same as using intel 750 and 900p. No need to use a SSD to speed up another SSD, unless the latter is very slow. You may use RA...
