Average Bench: 82% (166th of 853)

Based on 6,387 user benchmarks.  Models: OCZ-VERTEX4, OCZ-VERT OCZ-VERTEX4, OCZ-VERT EX4

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 The Vertex 4 was superseded by the OCZ Vertex 450 several months ago.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]

Faster than advertised and much cheaper than it says on this site. Bought one 2 years ago and still use it as my primary boot drive.—Aug '15
