Best 28TB internal hard drives
Researched by Deal.ai's shopping agent across stores on November 2, 2026. Prices below are today's.
Top pick: Seagate Exos X28 28TB (ST28000NM000C) — the enterprise-grade 7200 rpm CMR drive that's the sweet spot for 28TB: fast sequential reads, built for 24/7 duty, and the lowest price of the 28TB drives here. Best for bulk storage in a desktop, NAS or server where you want maximum capacity per bay.
Who the others suit:
- IronWolf Pro 28TB — pick this if you want Seagate's NAS-specific firmware, vibration tolerance and recovery service; it's the safer choice for a multi-bay NAS.
- Exos M ST28000NM003K — the newer Exos M platform; worth it if you want the latest generation and don't mind paying more.
- Exos ST28000NM001C — same family, but priced well above the X28; only worth it if you need that exact part number for a warranty-matched array.
- IronWolf Pro 4-pack — for building out a whole NAS at once.
All are 3.5-inch SATA 7200 rpm; check your enclosure's drive-height and power limits before ordering.
