Hi,
I use a trusty old 250GB Samsung 840 Evo as my L2-Cache for two HDDs.

According to CrystalDiskInfo that SSD's health is now at 69% (nice).
Is there any way to benchmark this disk to know, if it still performs well, without removing it from PrimoCache and formatting it (--> losing the cached data)?

I also have a few GBs of RAM assigned to those drives as L1 cache, if that's relevant.

Best regards
Colin

If your L2 cache has set up write cache space (https://kb.romexsoftware.com/en-us/2-pr ... ache-space), you can estimate L2 cache performance without loosing most cached data by testing a target volume. Remove L1, and enable defer-write, then you can run CrystalDiskMark etc to see the performance. Otherwise, I'm afraid there is no way to do it without loosing cached data. Re-configuring cache space will also cause the reset of cached data.

Thanks a lot, I'll try it the way you suggested.

UPDATE (just FYI): your recommendation worked perfectly and I got very SSD-like benchmark results. All still looks well (except for 4K 64 Thread values for some reason).
