It has nothing to do with cache block size. PrimoCache doesn't do the read-ahead or pre-fill the whole cache block. It caches data based on access, that is, if VLC or md5sum (in your case) read 1mb data, then PrimoCache will cache 1mb data. Even the block size is 10mb, PrimoCache still caches 1mb da...

Yes, as Nick7 said, cache block size doesn't help your problem.

Thank you for the confirmation. We will also do further study on this issue.

We find that to work with Stablebit DrivePool you need to add source disks of the pool to the cache task, not the drive pool.

Sorry, but I want to make sure if you restarted your computer after uninstalling and these filters are now not listed in the registry.

EPMVolFit is the driver for EaseUS partition manager, while EUBKMON/EUBAKUP is for EaseUS Todo Backup.
I suspect the problem may be related to these drivers.

Seems quite weird... So if you copy files to the drive E you don't see any value changes in the "Total Write (Req)", right? Can you open the registry editor and then locate to the branch "HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Class\{71a27cdd-812a-11d0-bec7-08002be2092f}&...

Thanks for the suggestion. We will consider it. I think it's easy to be implemented.

"Total Write (Req)" is 0, so PrimoCache didn't see any write IOs. It seems that all writes were bypassed and directly to the drive. Is the drive used for VMs? Or any other software installed might intercepts writes?

I see "Total Write (Req)" is 0 which means there was no any write IO requests to the disk pool. Does the disk serve for writing? Can you upload the screenshot of the full main dialog?
