1 TB desktop SATA hard drive

This Western Digital Caviar Green WD10EARS is a 3.5 inch internal hard drive with a 1 TB capacity. It spins at 5400 RPM and connects via a SATA 3 Gb/s interface with a 64 MB cache. The drive is supplied new as a bare unit.

Suitable for bulk storage.

The 5400 RPM spindle speed makes this drive appropriate for mass data storage, backups or media libraries where access latency is not critical. Systems that rely on a single mechanical drive for the operating system and applications will see slower boot and load times compared with faster-spinning or solid-state alternatives.

5400 RPM spindle speed is the deciding factor

The rotational speed determines sustained transfer rates and random-access responsiveness. If the workload demands the higher throughput of a faster spindle, this model will not meet that requirement.

Questions about this item

Will the 5400RPM spindle motor need replacement during the drive's lifespan?

The 5400RPM motor is sealed inside the helium-free enclosure; no user-serviceable parts exist, so the whole drive is replaced if the motor fails.

What limit appears first when writing continuously to the 64MB buffer?

Sustained writes fill the 64MB cache quickly, after which the 5400RPM platter speed becomes the throughput bottleneck.

How much heat and noise does the 3.5" SATA drive produce when running all day?

The 5400RPM Green-series design keeps heat and acoustic output low during continuous operation, drawing modest power from the SATA connector.
