[Feature request] Separation of L1 and L2 write policies

Hey all, I'm loving the program but one suggestion I want to make is that L1 and L2 be allowed to have separate write policies. The use case that I'm considering is that I have an 8GB L1 write cache in addition to having a 480GB SSD set to cache both reads/writes. I normally want the L1 cache to han...

Re: Somthing toward a "sticky:" Suggestiion for a configuration discussion for various PC usage patterns

I see it the same way. I use a small 384MB write-only L1 cache because Windows' memory manager already functions as a read cache. Using L1 as a both read/write cache typically causes write data to be flushed too often in my experience. If Windows' caching was as effective as you think, we wouldn't ...

Re: Somthing toward a "sticky:" Suggestiion for a configuration discussion for various PC usage patterns

Doesn't using L1 RAM cache for reads seem wasteful? Windows uses free memory for file system buffer so anything you reread will be fetched from RAM anyway. Since PrimoCache v3 I set L1 RAM cache to 100%-write so it is used for deferred writes only, and L2 SSD cache to shared read/write. I see it th...

Re: Feature proposal: allocating level1 cache in VRAM

VRAM wouldn't be very practical as a disk cache. While VRAM itself is very fast then it's still always connected to the rest of the system via a slow PCIe connection. This interconnect is much slower than system RAM at just 16GB/sec for PCIe v3.0. Conversely, modern DDR4-2666 has a bandwidth of 43GB...

Re: Can PrimoCache rival the Intel Optane System Acceleration ?

It's the reason that I used 'unsupported' rather than 'incompatible'. Not supporting Win7 on Z370 was a poor move on Intel's part but I still wanted to mention that Optane has not been validated for Win7 even though it's unlikely to cause issues. Now, that is a better argument, but do you mean Primo...

Re: Can PrimoCache rival the Intel Optane System Acceleration ?

I've never used Optane but have plenty of experience with SRT on a SATA SSD. In my experience, there's isn't that much difference between PrimoCache and the Intel solutions and you should get more or less the same performance. The major advantage of SRT is that it works at a BIOS level and will try ...
