Standard 3.5 inch hard drive with silver metal casing and green circuit board visible

Seagate

Seagate Exos X 28TB 3.5in SATA 7200 RPM 512MB Cache 2.5M MTBF internal hard drive

SKU CH-9EQD-KQK93

A 28 TB 3.5-inch SATA hard drive spinning at 7200 RPM with 512 MB cache and a 2.5 M MTBF rating for high-capacity desktop storage

  • 28 TB capacity stores massive datasets in a single 3.5 in drive
  • 7200 RPM spindle speed delivers high sustained throughput for large transfers
  • 512 MB cache buffers bursts to reduce latency during heavy workloads
  • 5 M hours MTBF rating supports continuous operation in data-centre environments
  • CMR technology ensures consistent write performance without shingled slowdowns

Capacity & Interface

The Seagate Exos X is a 28TB 3.5-inch internal hard drive that uses a SATA 6Gb/s interface. It spins at 7200 RPM and includes a 512MB cache to handle heavy write workloads. The CMR recording technology supports sustained performance in multi-drive arrays. Condition is new and the unit carries a 2.5M hour MTBF rating.

Who This Suits & Who Should Look Elsewhere

This drive suits operators building high-density storage pods, backup targets or surveillance archives where maximum capacity per bay matters. Buyers who need the low latency of solid-state storage or a smaller 2.5-inch form factor should look at a different product class. Systems limited to lower SATA speeds will not gain the full throughput benefit.

Deciding Specification

The 28TB capacity is the single figure that determines whether this drive fits the storage plan; it sets the raw terabytes per rack and drives the cost-per-terabyte calculation. Verify that the host controller and backplane support drives of this size before ordering.

Questions about this item

Does the 28TB Exos X drive ship with any cables, brackets or mounting screws?

The drive is supplied as a bare 3.5in unit; SATA data and power cables plus any mounting hardware must be sourced separately.

How do I decide between the 28TB CMR model and a lower-capacity alternative?

Choose the 28TB CMR version when you need the maximum areal density for hyperscale workloads; smaller capacities suit less dense deployments.

What does the 2.5M MTBF rating mean for a drive running 7200 RPM in a live server?

It represents a statistical mean-time-between-failures figure of 2.5 million hours under the manufacturer's specified operating conditions.
