I uninstalled Primocache and was still able to reproduce the issue of USB-3 devices dissappearing.

Obviously it isn't a Primocache issue. If anyone has more general troubleshooting advice, I'd love to hear it.

My first effort is to directly connect my drives to the MB, instead of via a PCIe ...

Nothing in the eventlogs

My Cache is once again empty (a surprise since it went over a month the last time). Not sure when it happened, I wasn't using the system much the last couple days.

I have 2 files in the C:\Windows\minidump folder. I don't know if they are related. Aug 28 and Aug 30 dates ...

To my surprise, the python script Robf posted does the job. It must use a different API than the process I use from cygwin.

I would have expected that all reads go automatically into L2 unless L2 is filled. And if L2 is filled, a "last used first out" approach should decide which block of L2 is discarded to make space for what you are just reading. Thats the expectation.

I have to think about if I can verify for ...

No, it isn't the pause.

I've setup a 64GB L1 cache in RAM and 2TB of L2 cache.

If I rapidly read 500 GB of data from a rotating media, most of it doesn't make it to L2.

I've found that if I read in ~60GB of data, then kill the reading app, the L2 cache gets a burst of data. Since my L2 cache is ...

As I continue to work with PrimoCache, I am less and less confident I know how to force data into the cache.

I recently emptied my L2 cache (all 2TB was emptied), now I have a 400GB of data I want to work with in the next 48 hours. I'm attempting to get it into the L2 cache, but it doesn't seem to ...

I know the L2 cache is limited to 2TB.

But I'm trying to add a 5TB drive as a volume to be cached, not to hold the cache. PrimoCache is refusing it. But it let me add a 1TB drive after it refused the 5TB drive, so it seems like 5TB may be beyond some limit?

Too bad the AsRock x99 Deluxe has not M.2 slot at all.

But it does. I have my current 2TB Samsung 960 Pro in it. Working fine.

I also have e a 1-port PCIe card, so I could go to 2 of the 2TB drives if it was warranted. For now, a single 2TB drive seems sufficient, but not excessive.

As per ...

They got 5900 MByte/s using four 951 M.2 cards. Those are specc'ed at 2150 MByte/s each.
So four 960 Pro (specc'ed 3500 MByte/s each) will presumeably result around 9600 MByte/s in total. And on the HP they got near 12000 MByte/s as I have heard.
