Page 8 : IOPS Scaling (Random) Performance

IOPS Scaling (Random)

We tested the drive’s ability to tackle multiple input/output operations, comparing the 10 TB WD Red (WD100EFAX) to the 6 TB WD Red. For more performance comparisons, please take a look at The Hard Disk Drive Performance Comparison Guide.

Although we don’t know what hard disk drive controller used in the 10 TB WD Red (WD100EFAX), we can see that it is significantly faster than the Marvell 88i1047-NDB2 controller used in the 6 TB WD Red. Its performance was particularly impressive in the 4 KB random write test.
