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.

Otázky k tomuto produktu
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.
