Answer: D

Explanation:

data size for flash mode exceeds 25% of the SSD capacity could cause the performance issues. Flash mode is a feature that allows vDisks to be pinned to SSDs for faster access, but it has a limit of 25% of the SSD capacity per node. If this limit is exceeded, some vDisks may be evicted from flash mode and cause disk latency2.
