3 TB SATA desktop drive

The WD Blue WD30EZRZ is a 3.5 inch internal hard drive with a 3 TB capacity. It spins at 5400 RPM and provides a 64 MB cache over a SATA 6.0Gb/s interface. The drive is designed for daily computing tasks in desktop systems.

Suits storage expansion not speed

This drive suits users adding bulk storage for documents, media or backups where sequential throughput is secondary. Builders who need low latency for operating systems, databases or heavy random workloads should look at solid state alternatives.

5400 RPM spindle speed

The 5400 RPM rotation rate defines the drive's sustained transfer rate and access latency. If your workload requires faster random performance, a higher spindle speed or flash-based device will be necessary.

Questions about this item

How does the 5400 RPM speed affect everyday file access?

The 5400 RPM spindle provides quiet, low-power operation suited for bulk storage and daily computing tasks rather than high-speed application drives.

What does the SATA 6.0Gb/s interface mean for transfer speeds?

The SATA 6.0Gb/s connection supports the drive's 64MB cache for burst transfers, while sustained rates follow the 5400 RPM mechanical limits.

Will this 3.5-inch drive fit my standard desktop bay?

The drive measures 147.00mm long, 101.60mm wide and 26.10mm high, matching the standard 3.5-inch desktop form factor.
