Re: HDD Power management.

Normally you'd only see a HDD "click" when it is parking the heads, or when the heads are resetting (i.e. in the event of a SMART failure of some type). Have you fully diagnosed the clicking drives to see if they report SMART errors, or have an unusual sleep period set on them (like ~5 seconds of in...

Re: Looking to Boost USB Drive Write Performance

Need to post screens of your Level-1 Cache options (the disk icon to the right), and your defer-write options (disk icon to it's right) so we can get a complete view of your settings. Additionally, if your backups are significant in size they may easily overwhelm your 5GB cache size, which will then...

Re: Caching HDD with SSD, settings wrong ?

Going to agree with Support - dropping the L1 cache size a bit will help boot times if that's one of your interests. It will force more of the Windows boot files into the L2 instead of the L1, and those don't need to prefetch at boot. You'll have to see if 16KB or 32KB is a better block size - the p...

Re: Caching HDD with SSD, settings wrong ?

The larger a cache is, and the smaller the block size, the more memory the cache task will consume tracking it all. By either reducing cache size or raising block size you reduce overall memory overhead required. That in turn increases memory available for either the OS, or apps, or to put back into...

Re: Caching HDD with SSD, settings wrong ?

Suggestions: 1) Remove all volumes from the cache task -except- the "C:" volume. 2) Turn on the "Start at Windows Boot" so it will prefetch when Windows starts up. 3) Change your Block Size from 4k to 16k (your memory overhead right now is huge at 5.25GB) You said you assigned the entire SSD to L2 a...

Re: Best way to set up Primo on my system?

To add to what Support indicated: I'd bump up the L1 size to 12GB, or 16GB if you don't run really memory-hungry apps/games. You can adjust the L1 size on the fly, but it will dump L1 cache contents each time you do it, so try one size for a while and see how it goes, then adjust and try again for a...

Re: Estimated capacity loss from miss-matched block size?

it means that when told to fetch something even as small as 1 4k cluster, Primocache will go and fetch the entire 32kb "block" that the cluster is within from the drive. PrimoCache just assign a 32KB cache block for this 4KB cluster (and its adjacent 32KB address range). It doesn't mean that PrimoC...

Re: prefetch and l1 cache question

Prefetch simply grabs what was in the cache at last shutdown and loads it back into the cache. You will never have a prefetch larger than the cache size. Done means it's done fetching the last cache contents after boot.

Re: Level 2 Caching on a PCIe 4.0 SSD

Rapid does something similar, though I don't think it's as good as Primocache (since it's a dedicated paid product). If you're asking if using deferred write when caching a target SSD with a L2 SSD is helpful, I still wouldn't do it. That's just my personal preference of course, and typically Suppor...
