Product overview

WD Blue 3TB (WD30EZAZ) is a 3.5-inch SATA desktop HDD in Western Digital’s WD Blue 3.5-inch PC HDD family; it first appeared at retail in February 2021. WD’s own documentation lists this SKU as 5400‑RPM class with a 256 MB cache, and the WD portfolio materials identify WD30EZAZ as an SMR (shingled) model.Sourcenewegg.com Sourcewesterndigital.com

Positioned as a budget HDD, it exists to deliver inexpensive bulk capacity for everyday PCs. With SATA 6 Gb/s and 3 TB in a 3.5-inch form factor, it’s a good fit for mass storage and a cold game library or budget upgrade; prefer SSDs for boot/apps and avoid heavy parity‑array writes due to SMR behavior. Not marked discontinued—WD still lists the SKU on its product page as of July 2026.Sourcewesterndigital.com
