High-capacity desktop storage

The Western Digital WD180EDGZ is an 18 TB internal hard drive built for desktop systems. It uses a 3.5 inch form factor and a SATA III interface to deliver 7200 RPM performance with a 512 MB cache. The drive is compatible with both Mac and PC platforms for broad system integration.

Suited for bulk data workloads

This drive fits users who need large-capacity storage for media libraries, backups or archival data on a standard desktop SATA port. It is not intended for laptops or small-form-factor systems that require 2.5 inch drives. Builders without a free 3.5 inch bay or a SATA connection should consider other form factors.

7200 RPM spindle speed

The 7200 RPM rotation speed determines the sustained transfer rate and access latency for sequential workloads. Verify that your system can accommodate a 3.5 inch SATA drive and that the 18 TB capacity matches your storage planning before purchase.

Questions about this item

How does the 7200 RPM speed affect everyday desktop performance?

The 7200 RPM spindle delivers lower latency and higher sustained transfer rates than slower drives, making it well suited for operating system boots, application loading and large file moves in a desktop PC.

What does the SATA III interface mean for maximum throughput?

The SATA III connection provides a 6.0 Gb/s link that sets the upper bound for data transfer between the drive and the motherboard.

Will this 3.5 inch drive fit in a standard desktop drive bay?

Yes, the 3.5 inch form factor matches the standard internal drive bay found in most desktop chassis and mounts with four side screws.
