Seagate Exos X22 20TB 7.2K SAS 12G LFF Hard Drive

The Seagate Exos X22 20TB 7.2K SAS 12G LFF Hard Drive (ST20000NM000E) is the base 20TB SAS model of the X22 line. It is listed without an encryption option, so it is the version to pick when encrypted media is not part of the requirement.

The interface is SAS at 12 Gbps, the spindle runs at 7200 rpm, and the drive is a 3.5in LFF unit with a 512 MB cache and 512e sectors.

People who buy 20TB SAS drives often maintain storage arrays that were populated at this capacity, and they need spares that behave identically. Others are building new capacity tiers where 20TB is the right match for their cost and rebuild-time targets.

The drive requires a SAS-capable backplane or controller.

There are no alternative part numbers on file for the ST20000NM000E.

This model is available new and refurbished, each with a warranty of 1 year or 3 years.
