The 128GB Plextor M5 Pro has a reasonable performance profile. With an effective speed of 442 MB/s it ranks just 5% below the average of the top ten user rated 128GB SSDs, a good result. The M5 Pro's server orientated deep queue read/write speeds clocked in at 345/282 MB/s, slightly above average. As a consequence of having fewer NAND modules, the 128GB version is around 40% slower at sequential writing than its 256GB sibling. The larger capacity M5 Pro represents significantly better value for money. In the 128GB category some manufacturers (Samsung/OCZ) are offering the same sorts of speeds as typically seen in the faster 256GB category. In terms of performance, those SSDs currently stand heads and shoulders above the rest of the 128GB pack. There are several better value for money alternatives to the 128GB M5 Pro in the group test[Feb '14 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 The Vertex 4 was superseded by the OCZ Vertex 450 several months ago.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]
