The 128GB Vertex 450 has a reasonable but somewhat unusual performance profile. The main weakness is its sequential write speed which is only 282 MB/s peak. This implies that the 128GB version has fewer NAND modules than both its larger 256GB sibling and several other leading 128GB models. Other SSDs, including some 128GB models can consistently achieve sequential write speeds in the 500 MB/s range. A handicap of this magnitude on a key performance metric would normally relegate an SSD to the lower divisions but the Vertex 450 offsets its poor sequential write speed with a record breaking 4K write speed of 158 MB/s which is the highest I have ever seen on any SSD. Overall the Vertex 450 has an average, but quirky, performance profile and is reasonably priced however there are both faster and cheaper alternatives available on the SSD leaderboard.  [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 The Vertex 4 was superseded by the OCZ Vertex 450 several months ago.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]
