Will the Level 2 cache for the disk prevent it from spinning down?

I am setting up level 2 cache for the first time. I have the HDD in my system set to spin down after 5 minutes of inactivity since I don't use them that often.

@geneo, L2 won't. But do you enable the defer-write for that HDD?

Sorry, I didn't mean to post in someone else's thread.
Yes, I do enable deferred write.

When Defer-Write is enabled, PrimoCache may prevent HDD from spining down too often, otherwise its C1 value will increase very quickly.
(BTW, I separate this topic from your original post which was in an irrelevant thread, making a new thread here.)
