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]

MORE DETAILS

The OCZ Agility 4 is a relatively old SSD and has been included in the group test as a reference. In terms of overall speed the Agility 4 lags the current ten market leaders by an average of around 30%, considering that the Agility 4 is only 16 months old this highlights just how quickly the SSD market has evolved over the last two years. It's probably not worth upgrading for the sake of more speed unless you have a specific use case that demands it but if you are looking for a speed upgrade, you will gain up to around 50% by going for the Samsung 840 Pro or the OCZ Vector. [Sep '13 SSDrivePro]

 Best User Rated
Why does UserBenchmark have a bad reputation on reddit?
Marketers operate countless reddit accounts. UserBenchmark’s data exposes their marketing spiel so they systematically attack our reputation.
Why don’t large PC brands support UserBenchmark?
PC brands profit greatly from flagship hardware like the 4090, 14900KS, and 7950X3D. We help users get similar real-world performance for less money.
Why don’t any youtubers promote UserBenchmark?
We don't sponsor youtubers, so they have no incentive to praise us. Moreover, brands pay more to market weaker products which puts their youtubers at odds with UserBenchmark.
Why does UserBenchmark have so many negative trustpilot reviews?
Trustpilot hosts user-generated online reviews. It's obvious that the 200+ UserBenchmark reviews, are mostly written by virgin marketing accounts. Real users aren't interested in promoting billon-dollar brands...
Why is UserBenchmark so popular with users?
Instead of pursuing lucrative sponsorships with billion-dollar PC brands, we have dedicated 13 years to publishing accurate real-world data. As a result, our users save millions every year and they return repeatedly.
The Best.
