Dell Constellation ES 1TB SATA drive

This Dell Constellation ES drive provides 1TB of storage in a 3.5 inch form factor. It spins at 7200 RPM with a 64MB buffer and connects through a SATA 6Gb/s interface. The unit is new and includes a caddy for installation.

Suitable for bulk storage in servers

This drive suits administrators who need reliable capacity for backups, archives or secondary data volumes. It is not for systems that require the throughput of solid-state storage or the density of 2.5 inch bays. Buyers needing higher rotational speeds or larger caches should consider other models.

SATA 6Gb/s interface determines compatibility

The drive uses a SATA 6Gb/s interface, so the host must provide a matching SATA port and 3.5 inch mounting space. Verify that the controller and backplane support this connection before purchase.

Questions about this item

Should I pick the 1TB 7200RPM model or a lower-capacity version?

This drive is offered as a single 1TB capacity with a 7200RPM spindle speed and 64MB cache.

What does the 7200RPM rating deliver in a desktop system?

The 7200RPM rotation provides faster sequential throughput and lower access latency than slower-spinning drives.

How does the SATA 6Gb/s interface affect real-world transfer speeds?

The SATA 6Gb/s link caps the maximum burst transfer rate at 6Gb/s, while sustained rates depend on the 7200RPM platters and 64MB buffer.
