Average Bench: 67.7% (406th of 911)

Based on 460 user benchmarks.  Models: OCZ-VERTEX3 MI, OCZ-VERT EX3 MI

This drive is another victim to the Sandforce 2281 controller's relative inability to handle incompressible data. The performance profile shows superb sequential read ability but relatively very poor sequential write and 4k read scores. With a real world speed of 371.4 MB/s and an AS SSD total score of 779 the MAX IOPS version of the Vertex 3 is below average by today's standards and there are significantly better deals available elsewhere. [Feb '12 SSDrivePro]


Above average average bench

The OCZ Vertex 3 MAX IOPS 240GB averaged 32.2% lower than the peak scores attained by the group leaders. This isn't a great result which indicates that there are much faster alternatives on the comparison list.


Avg. 4K Random Write Speed 71.4MB/s
Avg. 4K Random Read Speed 24.6MB/s

Above average consistency

The range of scores (95th - 5th percentile) for the OCZ Vertex 3 MAX IOPS 240GB is 33.4%. This is a relatively narrow range which indicates that the OCZ Vertex 3 MAX IOPS 240GB performs reasonably consistently under varying real world conditions.
