1TB 7200RPM Enterprise SATA HDD

The Seagate Constellation ES.3 ST1000NM0033 is a 1TB 3.5-inch internal hard drive spinning at 7200RPM with a SATA 6Gb/s interface and 128MB cache. It is built for desktop workstations and entry-level servers that need reliable bulk storage. The drive is supplied new and includes technologies such as Native Command Queueing and on-the-fly error correction.

Suited for capacity-focused builds.

This drive suits system builders who want large, affordable capacity for backups, media libraries or general-purpose data volumes. It is not for users who require the low access latency or high random IOPS of solid-state storage. Buyers needing 2.5-inch form factors or interfaces other than SATA should consider different products.

The 128MB cache size determines sustained throughput

A 128MB buffer helps smooth burst transfers and improves performance on sequential workloads such as video recording or large file copies. If your workload depends on very small random writes, the cache alone cannot overcome mechanical latency. Verify that your motherboard or controller provides a SATA 6Gb/s port to use the full interface speed.

Perguntas sobre este artigo

Will the 128MB cache need any maintenance or replacement over the life of the drive?

The 128MB cache is a permanent part of the drive controller and requires no separate maintenance or replacement.

What limit appears first when the 7200RPM platters run continuously under heavy write loads?

Sustained throughput is capped by the SATA 6Gb/s interface and the mechanical speed of the 7200RPM platters.
