The OCZ Vertex 460A is basically a tweaked re-release of last years Vertex 460. The two drives share the same controller and the same basic NAND, although the 460A apparently uses a newer version of Toshiba's 19nm MLC. Unsurprisingly there is little difference in performance between the 460 and 460A. In absolute terms, with peak sequential read/write speeds of 516/500 MBps and peak 4K random read/write speeds of 25/120 MB/s the 460A does have a rock solid performance profile but OCZ cannot afford to re-release 12 month old technology, at least not of they want to continue to compete with the likes of Samsung, SanDisk and Crucial who are continuously innovating. Overall the 240GB 460A still sits amongst the top handful of drives both in terms of outright performance and value for money. ^{[Jan '15 SSDrivePro]}

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 The Vertex 4 was superseded by the OCZ Vertex 450 several months ago.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