12TB Server Hard Drives

Key takeaways

• 477 listings match this collection right now.
• Mainstream nearline drives at 12TB are helium-sealed; the lower internal drag lets manufacturers add platters without the extra power draw and vibration an air-filled drive of the same count would have.
• This capacity is built as a 7,200 RPM nearline-class drive, not a 10K or 15K performance part, since 12TB is well beyond the limits those performance classes work within.
• A sealed drive cannot be opened for service, so a failed 12TB unit is replaced rather than repaired, and the array has to carry enough redundancy for a rebuild at this capacity.
