The 1TB SanDisk Ultra 3D SSD IOPS Scaling Results
Contents
IOPS Scaling (Random)
In these tests, we tested the drive’s ability to tackle multiple input/output operations. We compared the 1TB SanDisk Ultra 3D SSD (Price Check) against the 1TB WD Blue SSD. For more performance comparisons, please take a look at the Solid State Drive Performance Comparison Guide.
Even though the 1TB SanDisk Ultra 3D SSD (Price Check) 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 nCache 2.0 technology appears to have compensated for its limited NAND channels, allowing it greatly supersede the performance of the 1TB WD Blue SSD, even though they both use the same SDD controller.
