High-capacity 26TB enterprise drive

This refurbished Seagate Exos X drive delivers 26TB of storage in a standard 3.5-inch form factor. It uses CMR recording technology and a SATA 6.0Gb/s interface for broad compatibility. The 7200 RPM spindle speed and 512MB cache support sustained throughput for heavy workloads. A 2.5 million hour MTBF rating underlines its design for continuous operation.

Recertified condition and bare-drive delivery

The unit is factory recertified by Seagate, meaning it has been data-sanitised, tested and loaded with current firmware. It arrives as a bare drive without cables, mounting hardware or retail packaging. The supplier notes a three-month replacement warranty applies to these recertified devices. Buyers should plan for their own SATA data and power cables.

Verify bay space and workload fit

Confirm your chassis can accept a 3.5-inch drive measuring up to 147.00mm long, 101.85mm wide and 26.10mm high. The SATA interface requires a free SATA port and matching power connector on your host system. This model targets enterprise NAS, cloud and high-density RAID environments rather than typical desktop or laptop upgrades.

Questions about this item

Does the 512MB cache require any periodic maintenance or replacement?

No, the 512MB cache is solid-state memory soldered to the drive controller and has no user-serviceable parts or replacement schedule.

What limit appears first when the 7200 RPM platters run continuously at full throughput?

The SATA 6.0Gb/s interface caps sustained transfer rates, so the host bus becomes the bottleneck before the mechanical platters reach their maximum sequential speed.

How much heat and power does the helium-sealed 26TB mechanism produce during all-day operation?

The PowerBalance feature optimises watts-per-terabyte, and the helium fill reduces internal friction, keeping both heat output and power draw lower than air-filled drives of equivalent capacity.
