Can we use our ramdrive as L2 cache? I have a spare empty RAMDrive.
Cheers!

No. This is not suggested.

L2 cache is designed to use physical persistent storage devices.
If your RAMDrive is a physical device, you need to tick the option "Volatile Cache Contents" in the Advanced Level-2 Cache Options". Theoretically, using this kind of drives shall have no problems. However I'm sorry that we didn't test such cases.
If your RAMDrive is a virtual device, why not just use its memory as level-1 cache?

You mean virtual ramdrives? Directly using memory as level-1 cache is much faster than ramdrives.

So just use memory as level-1 cache instead of level-2 cache. This will be much faster.

I may point you to my most recent finding:

IMHO you can replace ANY RAM Disk using PrimoCache... and its twice as fast!
