I recall that enabling battery write-back caching can significantly improve write performance, but I wonder if it’s the optimal choice compared to the others listed.

I practiced a question similar to this, and I feel like Hugh queue depth might help with handling more I/O operations, but I'm not entirely confident.

I think RAID 0 could provide good performance, but it lacks redundancy, right? I need to double-check that.

I'm just gonna choose D and hope for the best. RAID 0 is like the storage version of nitro boost - it's gotta be fast, right? What could possibly go wrong?

I'm going to have to go with the option that sounds the most like a cheat code: battery write-back caching (C). It's gotta be the answer, right?

I'm going with C. Battery write-back caching is the secret sauce for a vSAN cluster. It's like adding turbo boosters to your storage system.
