Re: A theory about a problem that has always existed
Primocache can try to alleviate write bottlenecking when it uses write coalescing, but on a fragmented drive that feature is going to be reduced in effectiveness quite a bit. Best practice on external spinners may be to set an automated defrag routine a few times a week to try and help writes later ...

Re: New here. Here's setup, what more do you suggest.
How much data are you caching between your C and D drives? Even if you only have 1TB populated between the two, your data coverage rate is around 3.1% (32/1024), which means depending on how much data you access regularly your hitrate may suffer and the cache performance along with it. Typically jus...

Re: SD Card transfer rate
Welcome to the forums Sheldon. It should work well with an external drive, provided that drive uses a standard volume type recognizable by Windows. i.e. FAT32, NTFS, etc. If it has a proprietary software suite & driver that changes things a little, but if you're copying from your local NVMe to t...

Re: Need Advice on Very Low Hit Rate
Hit Rate simply relies on the same data (blocks) being read multiple times, and there being enough cache space to hold most used blocks. Are you using prefetch at Windows boot? It can help quite a bit to keep hit rate higher. Hard to say on the database volume, since it also has L2 caching. But the ...

Re: Level 2 cache not increasing speed
You're testing two layers at the same time - local drive access and network speed. Never do this, since it mucks up results and never tells you what's going on. On the machine you have Primocache installed: use CrystalDiskMark to test drive speed when Primocache is disabled, then when it is enabled....

Re: GpuRamDrive: GPU VRAM as RAMdisk: Game changer!?
It *may* be a good idea, but I think InquiringMind mentioned it should be for a separate product which I would agree with, or at best an add-on product. And the market segment for it would be much smaller than what Primocache currently has, so the idea of developing it as a paid product (for a demog...

Re: [2021-01-30] PrimoCache 4.1.0 released!
I use windows fastboot but don't wanna disable it because it is really usefull to reduce windows 10 starting times. That right there is going to cause ongoing issues for you for as long as you leave it enabled, no matter where your bluescreens are coming from. So in fact, you have two issues: a mis...

Re: Best Setup for new high end PC.
Hit Rate takes a while to build, and unless you are running a benchmark never gets over 95%. Typically I see between 20% and 80% depending on the application, it's read patterns, and how often I use it.

Re: Best Setup for new high end PC.
What InquiringMind said, though I'd keep block size between 32K and 64K. It's difficult to keep a drive defragmented enough for 128K blocks to really matter that much, and when you hit 64K blocks in Primocache the overhead is already minimal. As a side note: I wouldn't use an Inland SSD for any data...
