The 1TB WD Blue SSD (WDS100T1B0A) Review

Page 7 : IOPS Scaling (Random) Results

IOPS Scaling (Random)

In these tests, we tested the drive’s ability to tackle multiple input/output operations. We compared the 1TB WD Blue SSD to the 240 GB HyperX Savage SSD. For more performance comparisons, please take a look at the Solid State Drive Performance Comparison Guide.

Even though the 1TB WD Blue SSD is rated for enterprise-class endurance, its Marvell 88SS1074 controller is just not capable of handling too many simultaneous operations. It appears to handle up to 8 simultaneous transactions. Its limited NAND channels also held back its performance in large reads and writes.
