The Vertex 4 is just over a year old but thanks to its recent firmware update (1.5), it still manages to perform almost on a par with the best drives currently available. One of the striking aspects of the Vertex is its well-rounded performance profile. With an AS-SSD score of 1137 and a real world speed of 548 the Vertex 4 is able to cope extremely well with both server and consumer type workloads. This drive uses the new Indilux Everest 2 controller, which unlike the previous generations of this drive which used a SandForce controller, is able to cope admirably with both compressible and incompressible data. Overall, the Vertex 4 is a great performing SSD that said, there are better value for money (and younger) drives available, including the Vertex 4's own successor, the OCZ Vector. [Jun '13 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 popular with users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
