Seagate ST20000NM007H Exos X24 20TB 3.5 SAS 7200 internal hard drive

SKU CH-4EP2-7Q8WD MPN ST20000NM007H

A 20TB helium-sealed enterprise drive with SAS 12Gb/s interface, 7200 RPM speed, 285MB/s transfer rate, 550TB/year workload rating and 2.5M-hour MTBF

  • 20 TB capacity for massive data storage
  • SAS 12 Gb/s interface enables fast data transfer
  • 7200 RPM spindle speed delivers responsive performance
  • 5 million-hour MTBF ensures enterprise reliability
  • 550 TB/year workload rating supports heavy usage

Exos X24 20TB capacity

The Seagate Exos X24 is a 20TB 3.5 inch internal hard drive built for enterprise storage arrays and cloud infrastructure. It uses a helium-sealed design and a SAS 12Gb/s interface to deliver sustained performance in multi-drive environments. The drive targets operators who need maximum rack-space efficiency.

550TB annual workload and 2.5M-hour MTBF

The drive carries a 550TB per year workload rating and a 2.5 million hour MTBF, supporting heavy write cycles typical of data-centre operations. Advanced write caching helps maintain throughput up to 285MB/s. PowerChoice and PowerBalance features let administrators tune power draw during active and idle periods.

SAS 12Gb/s interface limits

The SAS 12Gb/s link caps burst transfer speed at the interface ceiling, so sustained rates sit at the drive's 285MB/s maximum. The 7200 RPM spindle speed and helium platform reduce latency but cannot exceed the physical media transfer limit. Systems without a 12Gb/s SAS controller will not reach the rated throughput.

أسئلة حول هذا المنتج

Will the 12Gb/s SAS interface on this 20TB Exos X24 work with my existing 6Gb/s SAS backplane?

Yes, the SAS 12Gb/s interface is backward compatible with 6Gb/s and 3Gb/s SAS controllers and backplanes, so the drive will operate at the speed of the slower link.

How can I verify the 7200 RPM helium-sealed drive is healthy after installation?

Check SMART data for reallocated sectors and run a full surface scan; the 2.5M-hour MTBF and 550TB/year workload rating reflect design targets, not a pass/fail threshold.

Does the bare ST20000NM007H include a mounting bracket or cables?

No, this is a bare drive only; you must supply your own 3.5-inch mounting hardware and SAS data and power cables.
