About the WUH721414AL5204
The Western Digital Ultrastar DC HC530 (WUH721414AL5204) is a 14TB hard drive built for enterprise and data center use, with a SAS 12Gb/s interface for connection to SAS controllers and backplanes common in servers and storage arrays. This capacity and interface combination suits bulk storage, backup targets, and capacity-oriented storage pools where sequential throughput and large usable space matter more than low latency.
Each unit in our inventory of this part number has gone through the same verification process before listing. Of the 18 units tested, all 18 passed, and recorded power-on hours range from 22,235 to 44,137 with a median of 25,170. Sequential benchmark results came back at a median of 260 MB/s read and 263 MB/s write across the tested units, consistent with expectations for this drive class.
Most of the tested drives (17 of 18) fall into the Standard Use tier based on recorded power-on hours, with one unit in the Value tier. Data was fully sanitized on every drive using either NIST 800-88 overwrite or SCSI format unit methods with read-back verification before resale.

WUH721414AL5204 questions
What workloads is this drive suited for?+
As a 14TB SAS hard drive, it is suited to capacity-oriented workloads such as bulk storage, backup targets, and storage pools in servers or storage arrays, where sequential throughput and usable space are the priority.
What interface and systems is it compatible with?+
This drive uses a SAS 12Gb/s interface and connects to SAS controllers, HBAs, or backplanes found in servers and storage enclosures that support SAS drives.
What does this store test on each unit?+
Every unit undergoes a sequential and random read/write benchmark, a full extended (long) self-test across the whole surface, a power-on hours cross-check against an independent on-drive log, a NIST 800-88 sanitize with read-back verification, and a SMART health read covering reallocated, pending, and uncorrectable sectors plus power-on hours.
What do the usage tiers mean for this model?+
Units are grouped by recorded power-on hours: Standard Use covers 20,000 to 40,000 hours, which applies to 17 of the 18 tested units, and Value covers over 40,000 hours, which applies to 1 unit.
How was data removed from these drives before resale?+
Each drive was sanitized using either a NIST 800-88 overwrite process or a SCSI format unit operation, both followed by read-back verification to confirm the sanitize completed successfully.
