The Vertex 450 is the third SSD OCZ have released in the last eighteen months. The 450 features an updated version of the now somewhat proven Indilinx Barefoot controller which was first seen in the Vector just over 9 Months ago. The core performance figures for the Vertex 450 are disappointingly weaker, albeit marginally, than both the Vector (by 16%) and the Vertex 4 (by 11%). The Vertex 450 is currently retailing for more than the Vertex 4 and roughly the same as the better performing Vector so the 450 cannot be recommended at this time. That said the 450 is still amongst the top ten SSDs currently on the market and will be well worth consideration when prices drop after retailers have had a chance to build up stock. [Sep '13 SSDrivePro]

MORE DETAILS

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 The Vertex 4 was superseded by the OCZ Vertex 450 several months ago.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

 Best User Rated
Why does UserBenchmark have a bad reputation on reddit?
Marketers operate thousands of reddit accounts. Our benchmarks expose their spiel so they attack our reputation.
Why don’t PC brands endorse UserBenchmark?
Brands make boatloads on flagships like the 4090 and 14900KS. We help users get similar real-world performance for less money.
Why don’t youtubers promote UserBenchmark?
We don't pay youtubers, so they don't praise us. Moreover, our data obstructs youtubers who promote overpriced or inferior products.
Why does UserBenchmark have negative trustpilot reviews?
The 200+ trustpilot reviews are mostly written by virgin marketing accounts. Real users don't give a monkey's about big brands.
Why is UserBenchmark the gold standard for users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
