Build NAS storage that can keep pace with growing file sets, backup targets, and shared workloads. Western Digital Red Pro 22 TB delivers high-capacity SATA storage in a 3.5-inch form factor suited to multi-bay NAS platforms and rack-mounted arrays. The larger capacity helps reduce the number of drives required for a given storage target, which can simplify planning, cabling, and expansion. Red Pro is a strong fit when the storage system must serve multiple users, hold large datasets, and remain online through long duty cycles. In practical terms, that means fewer trays consumed by capacity growth and more room to design around performance, redundancy, and future expansion. For procurement teams, it is a straightforward way to justify premium drive pricing: more usable capacity per bay, less hardware sprawl, and a drive family aligned to NAS deployment expectations. Choose this model when consumer-grade disks are no longer enough and the storage stack needs a drive built for shared, always-available infrastructure.
