L2 Cache and Encrypted Data

[ethercore]

Hello!

I'm trying to get some clarity on the L2 Cache and supported encryption methods. I intend to use a couple of SSDs in RAID0 as my L2 Cache, but I want to make sure that any encrypted data from my cached volumes doesn't end up getting written to my L2 Cache unencrypted.

Based on my research, it seems like PrimoCache supports volumes with Bitlocker enabled - in other words, only encrypted data would be written to L2 Cache. Is this correct? Are there any Bitlocker setups where it would not be written to L2 Cache encrypted?

Veracrypt is another very popular solution, but I could find less information about how it works with the L2 Cache. It seems like PrimoCache would see any mounted Veracrypt volume as unencrypted and write it to L2 unencrypted. Is this correct? Is there any setup where PrimoCache L2 can be used with VeraCrypt safely?

Thanks!

Yes. In Windows 10/11, no additional setup needed. Please see viewtopic.php?p=11990#p11990

Mounted Veracrypt volumes are not supported by PrimoCache.

Thank you.

1. Does the Bitlocker support work for whole drives, partitions, as well as mounted VHD?

2. Will you ever implement an encrypted L2 Cache as an optional feature? I think even the old ReadyBoost was encrypted. This seems like a valuable feature for some people.

Sorry, but no, it's not the program's goal. L2 cache stores encrypted data if data have already been encrypted.
