1 TB Constellation ES drive

The Seagate Constellation ES ST1000NM0011 is a 1 TB internal hard disk drive built for 3.5 inch bays. It spins at 7200 RPM with a 64 MB cache and connects through a Sata 6.0 Gb/s interface. The unit is new and sold without cables or manuals.

Sata 6.0 Gb/s throughput limit

The Sata 6.0 Gb/s link caps sustained transfer rates at the interface maximum, so sequential reads and writes cannot exceed that ceiling. Random I/O performance is further bounded by the 7200 RPM rotational latency and the 64 MB cache size. Workloads demanding higher bandwidth or lower latency will hit this bottleneck.

3.5 inch form factor and mounting

The 3.5 inch form factor requires a standard drive bay and four mounting screws in a desktop or server chassis. No rails, brackets or adapters are included, so installers must supply their own hardware. The bare drive design means handling care is needed to avoid PCB damage during installation.

Questions about this item

Which capacity of the Constellation ES ST1000NM0011 should I choose for a desktop storage upgrade?

The drive provides 1TB of storage on a single 3.5" platter, matching the capacity listed for this model.

What does the 7200RPM speed mean for everyday desktop use?

The 7200RPM spindle delivers faster sequential throughput and lower access latency than slower desktop drives.

How does the SATA 6.0Gb/s interface limit real-world transfer rates?

The SATA 6.0Gb/s link caps sustained transfers at the interface maximum, while the 64MB cache absorbs burst I/O.
