Real-World Drive Speed with 8TB HGST Ultrastar He8 Hard Drive (DiskTester fill-volume)

Get HGST 8TB Ultrastar He8 Hard Drive or OWC Thunderbay 4 RAID-5 edition at OWC.

As explained in Reader Question: Drive Speed of 6TB vs 8TB Hard Drives, real world hard drive speed is primarly a function of capacity utilization.

In fact, capacity utilization dominates the performance equation and is thus the only realistic metric for transfer speed when real-world peformance considerations come into play. Other benchmarks are largely context-dropping irrelevancies.

Moreover, if a drive is partitioned to use a volume on the fast part of the hard drive, seek time across that volume also drops (because the physical distance is tighter, the drive heads have less distance to travel).
