WD Red HDD Spec and Price in the United States
The base WD Red line is the entry NAS drive, and the reason the Red Plus exists: from 2TB up these SKUs are SMR (shingled magnetic recording), which WD discloses on the product brief as unsuitable for RAID-heavy write workloads. They spin at 5400rpm with a 256MB cache, carry NASware, and are fine for single-drive or lightly-written home NAS use — the three-year warranty and the price gap versus Red Plus are the honest signals that this is the capacity-over-durability pick.
Prices exclude sales tax.
