Page 8 : IOPS Random Scaling Performance

IOPS Scaling (Random)

In these tests, we tested the drive’s ability to tackle multiple input/output operations. 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.

The LSI 7101B hard disk drive controller used in the 8TB WD Gold is definitely faster than the LSI TT07143 controller use in the 6TB WD Black. However, you can see that Western Digital optimised it for random write performance. Together with the HGST Media Caching Technology, it trades some random read performance, for a big boost in random write performance, particularly in small, random writes.
