The 8TB WD Gold Datacenter Drive (WD8002FRYZ) Review

Page 9 : IOPS Sequential Scaling Performance

IOPS Scaling (Sequential)

In these tests, we tested the drive’s ability to tackle multiple input/output operations. Again, we compared the 8 TB Western Digital Gold to the 6 TB Western Digital Black – the fastest desktop-grade hard disk drive in Western Digital’s arsenal. For more performance comparisons, please take a look at The Hard Disk Drive Performance Comparison Guide.

It is obvious that the “price” for almost doubling the small random write performance is poorer sequential read and write performance.
