Seagate Exos X20 20TB 7.2K SAS 12G LFF SED-FIPS Hard Drive

The cache figure tells the generation of the Seagate Exos X20 20TB 7.2K SAS 12G LFF SED-FIPS Hard Drive (ST20000NM005D): 256 MB, half of what the later Exos families list. It is an Exos X20 model, an earlier family.

Otherwise it is a high-capacity SAS enterprise drive, with 20TB, a 7200 rpm spindle and a 12 Gbps interface, in a 3.5in LFF body with 512e sectors. The encryption label is SED-FIPS.

People order this model to extend or repair systems that were built with X20 drives. A newer-family drive of the same capacity would work in many cases, but a pool that is meant to stay uniform is easier to support with the identical model.

If you are specifying new equipment instead, compare the cache and family against the later 20TB SAS drives before deciding.

No alternative part numbers are listed.
