Enterprise-class storage drive

The DELL Constellation ES.3 PCH77 is a 2000GB 3.5in SATA hard drive built for continuous operation in servers and workstations. Its 7200RPM spindle speed and 128MB cache suit IT professionals who need dependable bulk storage for archives, backups or secondary data volumes.

2TB capacity with 7200RPM throughput

The drive delivers 2000GB of space for large file sets, media libraries or database files. Sequential transfers benefit from the 6Gb/s SATA link and 128MB buffer, while random I/O remains limited by mechanical latency, so sustained heavy database workloads or virtualisation clusters will hit performance ceilings.

Bare 3.5in SATA drive for standard bays

Installation requires a free 3.5in bay, a SATA data cable and a SATA power connector from the host system. No mounting brackets, cables or controller cards are included, so builders must supply those parts. The bare-drive format keeps the package minimal for integrators who already have cabling and trays on hand.

Questions about this item

Will the 3.5-inch SATA 6Gb/s interface work with an older motherboard that only has SATA 3Gb/s ports?

Yes, the drive runs at 7200RPM on a SATA 6Gb/s interface and is backward compatible with SATA 3Gb/s ports, so it will work with older motherboards at the lower speed.

How can I verify the 128MB cache and 7200RPM speed are active after installation?

Use a tool like CrystalDiskInfo or the BIOS drive information page; it will report the model ST2000NM0033 with 128MB buffer and 7200RPM rotational speed.

Does the bare drive include mounting screws or a SATA data cable, or must I buy them separately?

The bare drive ships without mounting screws or a SATA data cable; both must be purchased separately if your chassis or motherboard does not already provide them.
