Enterprise bulk-data drive

The Seagate Constellation ES.3 ST2000NM0033 is a 2000 GB 3.5-inch internal hard drive built for 24x7 operation in storage arrays and servers. Its SATA 6.0Gb/s interface and 7200 RPM spindle speed serve workloads that need sustained throughput rather than burst performance.

Bare-drive delivery

The unit ships as a bare drive without cables, brackets or mounting screws. Integrators must supply their own SATA data and power cables plus any carrier required by the target chassis or backplane.

128 MB cache buffer

A 128 MB cache helps smooth mixed read and write streams in multi-user environments. Buyers who need a larger buffer or a different interface such as SAS should evaluate other models in the same series.

Questions about this item

Will the 128 MB cache need replacement or firmware updates over time?

The 128 MB cache is built into the drive and requires no user maintenance or replacement during the product life.

What limit appears first when the 7200 RPM drive runs sustained workloads?

The 4.16 ms average latency and SATA 6.0 Gb/s interface set the practical throughput ceiling under continuous use.

How much noise, heat or power does the 3.5 inch drive produce running all day?

Designed for 24x7 operation with best-in-class energy efficiency, the 1.40 lb unit fits standard 3.5 inch bays and meets enterprise thermal limits.
