Western Digital (WD) Gold 12TB Hard Drive Review

We tested the drive with a few workload scenarios to see how it might perform in a real life setting compared to the latest 12TB Seagate IronWolf Pro.

File Server:
File Size: 512MB,  Block Size: 16KB,  I/O Queue Length: 128,  Read/Write: 80% / 20%,  Seq/Random: 0% / 100%
Web Server:
File Size: 1GB, Block Size: 16KB,  I/O Queue Length: 64, Read/Write: 100% / 0%, Seq/Random: 0% / 100%
Workstation:
File Size: 1GB, Block Size: 16KB,  I/O Queue Length: 64, Read/Write: 70% / 30%, Seq/Random: 50% / 50%
Database:
File Size: 2GB, Block Size: 4KB,  I/O Queue Length: 128, Read/Write: 90% / 10%, Seq/Random: 10% / 90%

With both drives having a 7,200rpm spindle speed and the same amount of cache at 256MB, the greater areal density of the Seagate platters (923 Gbit/inch²) over the WD ones (864 Gbit/inch²) give it the edge in these scenario tests.
