cpqDaLogDrvPerfWrites reports the count of write requests processed against a logical volume, expressed in writes per second. This lets an admin see write-side demand on a specific RAID volume separately from its read activity, which matters because writes typically cost more in a parity-based RAID level. For example, a volume built on RAID 5 that shows heavy and sustained writes-per-second would prompt an admin to consider whether that RAID level is the right fit for the workload given its write-penalty overhead.
