WD Blue 2TB SATA desktop drive

The Western Digital WD20EARZ is a 3.5 inch internal hard drive with a 2TB capacity. It connects through a SATA 6.0Gb/s interface and spins at 5400 RPM with a 64MB cache. The drive is built for everyday desktop computing tasks.

Suits general storage needs not high speed workloads

This drive fits users who need affordable bulk storage for documents, media files and backups in a standard desktop PC. It is not suited for applications that demand sustained high throughput or low latency such as video editing scratch disks or database servers.

5400 RPM spindle speed defines responsiveness

The single specification that determines suitability is the 5400 RPM rotational speed. It governs the drive's random access performance and sustained transfer rates making it appropriate for capacity focused roles rather than performance critical ones.

商品問答

How can I confirm the WD20EARZ is running at 5400 RPM after installation?

Check the rotational speed reported in your BIOS or UEFI, or use a tool such as CrystalDiskInfo to verify the 5400 RPM figure matches the drive specifications.

Does the WD20EARZ retail box include a SATA data cable and mounting screws, or must I buy them separately?

The drive itself is supplied in the box; cables and screws are not included and must be sourced from your case or motherboard accessories.

Which cache size should I choose for everyday desktop use with the WD Blue 2TB drive?

This model provides a 64MB cache, which is the only cache option available for the 2TB capacity in the WD Blue series.
