Resolve the model mismatch
The linked retail identifier is WDBC9V0080HH1-WRSN, with 8TB, 5,640rpm and 128MB cache in the title. The catalogue instead names WD80EFPX. Western Digital specifies 256MB for that revision and 128MB for WD80EFZZ. The retailer’s cache figure does not prove which mechanism will arrive; confirm the drive label before matching a NAS compatibility list.
Match the enclosure and workload
Red Plus targets compatible NAS systems with up to eight bays and workloads up to 180TB per year. That workload counts reads and writes together. Check the enclosure maker’s supported models, capacity limits and installation instructions. This is a bare SATA drive, so it needs the host’s power, mounting and data connection rather than a USB cable.
Plan where the NAS will sit
A mechanical disk brings vibration and operating sound into the enclosure, even when a product family is marketed for quieter use. Place the NAS on a stable, ventilated surface away from a microphone or sleeping area. The checked listing does not establish a single drive revision, so this guide does not promise a particular noise or power figure.
Separate redundancy from backup
A mirror can help keep data available after one disk fails, but it also repeats deletion and many unwanted changes. Keep an independent backup with a recovery process you have checked. Two 8TB disks in a mirror do not provide 16TB of usable mirrored capacity; formatting and the NAS layout also reduce the space shown to users.
Buy the confirmed revision
The manufacturer’s WD80EFPX and WD80EFZZ sheets both describe CMR 8TB drives, but cache and transfer ceilings differ. Treat the table’s revision-specific numbers as conditional, not as a promise about this retail box. Choose only after the seller or supplied label establishes the model your NAS supports, and retain the purchase details for warranty eligibility.

The final check
A good fit if…
You have a compatible NAS and can confirm the actual drive label before relying on revision-specific specifications.
Keep in mind
The retailer and catalogue disagree. Do not assume WD80EFPX, its cache, speed or acoustic figures from this ASIN alone.
