OCZ Vertex 4 512GB SSD Initial Review - Vertex Returns to its Indilinx Roots (Firmware Progression Testing)
HDTune tests a similar level of features that HDTach does, but with a slightly different access pattern and thus can provide us with an additional set of benchmark numbers to compare between storage configurations. Here we can get the minimum, maximum and average transfer rates as well as the burst rates and access times. CPU utilization has proven negligible with modern processing horsepower, and is no longer included.
This test normally shows just how inconsistent burst testing an SSD can be, but since burst tests are sequential in nature, the Vertex 4 repeated its sequential read issue.
More sequential read issues with the Vertex 4 made it perform sub-par and it was unable to saturate SATA 6Gb/sec with 8MB block sequential reads. We really hope to see sequential performance improve with further updates.
