WD Blue 4TB (HDD)
A beginner-tier 4TB mechanical HDD, the WD Blue is framed as the Seagate alternative for cheap bulk storage. It's a straightforward pick for archives, backups, and capacity where speed doesn't matter. It is not performance storage, so games and active workloads belong on an SSD; the WD Blue earns its place purely as low-cost spinning capacity.
