Near the end of the legacy Mac Pro lifecycle (2010–2012), Apple offered massive 2TB and 3TB multi-terabyte arrays directly from the factory.
- Exact Model: HDS722020ALA330 (2TB, 7200 RPM, 32MB Cache)
- The Breakdown: Generally considered the most stable mechanical drive choice ever offered natively by Apple. They ran hot, but they survived brutal environments.
- Common Failures:
- Overheating-Induced Lifespan Drops: Because these drives use up to five internal platters, they run significantly hotter than low-capacity drives. If the Mac Pro's internal intake fans become blocked with dust, these drives suffer premature mechanical failure.
- Stiction: The slider mechanism physically sticks to the highly polished platter surface when parked, preventing the platter from spinning after a long system shutdown.
