  • 2TB capacity for large-scale storage
  • 7200 RPM spindle speed for quick data access
  • 128MB cache buffer to accelerate read and write operations
  • 6Gb/s SAS interface for reliable enterprise connectivity
  • 5-inch form factor fits standard server bays

Enterprise 2 TB SAS drive

This Seagate Constellation ES.3 unit delivers 2000 GB of storage on a 3.5-inch SAS 6Gb/s interface with 7200 RPM spindle speed and 128 MB cache. It arrives as a lot of 10 drives, each reporting zero hours of operation. The hardware targets server and storage-array installations that require dual-port SAS connectivity.

RAID arrays and nearline storage

The drives suit administrators expanding RAID sets, populating JBOD enclosures or refreshing nearline tiers in enterprise arrays. They are not for desktops or workstations that lack a SAS controller and backplane, nor for systems requiring single-port consumer interfaces.

12-port SAS HBA or RAID controller required

A compatible 6 Gb/s SAS host-bus adapter or RAID controller with enough free ports is the single specification that decides fit; without it the drives cannot communicate with the host.

商品問答

Will the 3.5" SAS 6Gb/s interface on the ST2000NM0023 work with my older 3Gb/s SAS controller?

The drive uses a 6Gb/s SAS interface that negotiates down to 3Gb/s on older controllers, so it will function at the lower link speed.

How can I verify the 7200RPM drive is running correctly after installation?

Check the SMART attribute for spin-up time and confirm the reported rotational speed shows 7200RPM in your RAID or OS utility.

The listing mentions a lot of 10 drives — does each unit include a SAS cable or mounting screws?

The drives are supplied as bare units only; SAS data cables, power cables and 3.5" mounting screws must be purchased separately.
