Seagate Constellation ES.3 4TB drive
The Seagate ST4000NM0023 is a 4TB 3.5-inch internal hard drive spinning at 7200RPM with a 128MB cache and a SAS 6Gb/s interface. It is built for server and storage-array environments where sustained throughput and vibration tolerance matter. The unit ships as a zero-hours drive from the Constellation ES.3 line.
Server and array deployments
This drive suits administrators expanding SAS-based RAID arrays, backup targets or nearline storage tiers that demand 7200RPM performance and dual-port SAS connectivity. It is not appropriate for desktop PCs, laptops or external enclosures that lack a SAS controller or backplane. Buyers who need a single-drive upgrade for a consumer motherboard should look elsewhere.
SAS 6Gb/s interface
The single specification that decides fit is the SAS 6Gb/s interface; the drive requires a compatible SAS HBA, RAID controller or backplane to operate and will not function on ports that support only other protocols.

Bu ürünle ilgili sorular
What controller and port does the ST4000NM0023 need to operate?
It requires a SAS host-bus adapter or RAID controller with a 6Gb/s SAS port and a compatible cable or backplane.
Can the 7200RPM SAS drive share a backplane with 6Gb/s SAS SSDs?
Yes, the drive uses the same 6Gb/s SAS interface, so it can populate the same backplane as SAS SSDs running at that speed.
How can I confirm the 128MB cache is active after installation?
Run the built-in Drive Self Test and check the controller BIOS or management utility; both will report the 128MB buffer size.
