The Seagate IronWolf 12TB delivers substantial storage capacity with fast sustained transfer rates of 250MBps, making it well-suited for NAS environments. PCWorld noted its vibration detection and compensation capabilities, which help prevent tracking issues in multi-drive setups. While it offers solid performance for high-capacity storage, it comes with a shorter warranty and lower MTBF rating compared to its Pro counterparts, and lacks the two free years of Seagate's recovery service included with higher-tier models. This drive is ideal for users seeking reliable, high-capacity NAS storage without the premium price tag of the Pro line.

Strengths
  • — Tons of capacity at 12TB
  • — 250MBps sustained transfer rates
  • — Vibration detection and compensation feature
Watch-outs
  • — Shorter warranty and lower MTBF rating than the Pro version

WD Red Plus 14TB
5 sourcesall derived$841.45as of Sep 28

TechRadar reviewed the WD Red Plus 14TB and noted its reliability in NAS environments, though it found the pricing not competitive. The drive features a helium-filled design, 550TB/year workload rating, and delivers read speeds near 265MB/s.

  • — Helium-filled design for reduced resistance
  • — Capable of reading speeds close to 265MB/s and writing 250MB/s
