Not getting any Read hits on RAW photos

[flowerdealer]

I have a 12gb L1 ram cache and a 60gb L2 cache, which I want to accelerate Reads on raw images on a regular HD. Current cluster size is at 4kb. When using DXO photolab to read the images, I'm not seeing increased performance, and pretty much getting a 0% hit rate on the drive. I've tested with games before and it seems to work, but not sure why it's not working in this case.

Do you see "Total Read" in the statistics increases when you read the images?
To avoid the influence from Windows's internal file caching, you may check this on the first time of reading images since Windows boot.

Yes, Total Read increases, but not cached read.

Please upload a screenshot of the PrimoCache main dialog which shows the cache configuration and statistics.
Thanks.

Will do, is there any way to browse the cache to see actually is on it?
