The 128GB Vertex 4 has an average score of 90.5% which is the highest we have seen to date for a 120-128GB SSD. We have in excess of 100 UBM samples for the Vertex 4 and they show that the 128GB Vertex 4 performs superbly outside the lab. With peak sequential read/write speeds of 508/391 and averages of 398/325 MB/s the Vertex 4 manages to average around 75% of its peak sequential speeds, a very impressive result. The Vertex 4 was superseded by the OCZ Vertex 450 several months ago. OCZ release new versions with minor tweaks approximately every six months. Comparing the Vertex 450 to the Vertex 4 shows that the move to 20nm flash and a new Indilinx controller has reduced overall performance by around 15%, so the older Vertex 4 is actually faster than its successor. ^{[Feb '14 SSDrivePro]}

The Crucial M4 is one of the oldest SSD's to have made it into the group test. When it was released its primary competitors were Sandforce based drives which suffered from two major problems: reliability and weak incompressible data performance. As a result this drive was one of the top drives of its time. That was back in Apr '11. Today the M4 is no longer able to compete and scores below average (377.9 MB/s) on the Real World Speed Index benchmark and way below average (676) on the deep queue depth orientated AS-SSD Total score benchmark. Of course these figures are still far faster than any mechanical hard drive and owners of this drive should feel in no hurry to upgrade. People looking to make a new purchase will find much better value elsewhere. ^{[Apr '13 SSDrivePro]}
