The FlashArray Purity GUI provides detailed performance analytics under the Analysis > Performance tab. To view the external (host-side) write latency for a specific volume, an administrator navigates to this section, selects the "Volumes" view, and then chooses the specific volume from the list. The performance graph displays several metrics simultaneously. By deselecting other metrics like "Read" and "Mirrored Write" (internal replication latency), the administrator can isolate and clearly view the "Write" latency trend, which represents the average time taken for write I/O as experienced by the connected host.

A. The Health > Network path shows port-level statistics like bandwidth and errors, not volume-specific I/O latency.

B. The Storage > Volumes > Details path shows configuration and capacity information for a volume, not detailed, time-series performance graphs.
