Seagate Exos X24 20TB 7.2K SAS 12G LFF SED Hard Drive

Twenty terabytes on a SAS interface: that is the pairing in the Seagate Exos X24 20TB 7.2K SAS 12G LFF SED Hard Drive (ST20000NM005H). The link speed is 12 Gbps, the spindle speed is 7200 rpm, and the drive is a 3.5in LFF model with a 512 MB cache and 512e sectors.

Encryption is listed as SED, so this is the self-encrypting variant. A drive in this position often goes into a storage shelf or server where SAS cabling is already in place and where encrypted media is a requirement.

Compared with the 24TB SAS drive, this one gives up some capacity per bay, which can be the right trade if rebuild times or the cost per drive are a concern. Over a large array, the difference in drive count adds up either way.

No alternative part numbers are listed, so ST20000NM005H is the number to use in orders and asset records.

We can supply it new, refurbished or used. New and refurbished drives have a warranty of 1 year or 3 years, and used drives have 90 days.
