OCZ Vertex 4 SSD review update

Synthetic Benchmarks

---

HD Tune Pro

The average sequential read speed is 483.4 MB/s. Let’s compare this with some recently tested SSDs in the table below.

With the original shipping firmware, I was not able to run the HD Tune sequential reading test. This has been fixed with firmware 1.4, and while the OCZ Vertex 4 is not the fastest reading drive, it is still an excellent performer.

ATTO disk benchmark

ATTO has become a standard tool for measuring the data throughput of HDDs and SSDs. It measures the performance of reading and writing, using different file sizes and block sizes.

The reading speed results on the OCZ Vertex 4 are extremely impressive, topping out at just over 541MB/s, and the writing speed is also very impressive topping out at over 465MB/s.

CrystalDiskMark 3.0

Crystal Disk Mark is quite a handy benchmarking application, as it focuses on the file sizes that can cause a problem on a system drive.

As we can see in the above screenshots, the OCZ Vertex 4 is performing extremely well.

AS SSD Benchmark

AS SSD benchmark is a benchmarking tool specifically designed to test SSDs. The application tests sequential reading and writing performance, including 4K random reading and writing performance.

AS SSD benchmark also tests 4K threaded performance. This is very exciting, as this test is the first available test that I am aware of, that simulates how a PC operating system actually works. A modern PC and OS, such as Windows Vista/7 does not just run a single thread at a time, it runs many threads. The AS SSD benchmark "4K 64Thrd" tests run 64 threads simultaneously throughout the test. If this result is good, then you can be pretty sure the drive will perform extremely well as a system drive.

After the tests complete, AS SSD benchmark derives a total score for the drive being tested. This is based on all aspects of the test results, and gives an indication of how the drive is performing overall.

Now let’s look at the result from the OCZ Vertex 4 in the form of a screenshot. All our other comparison drives’ results are presented in the form of a graph.

The OCZ Vertex 4 is showing quite astonishing performance in the AS SSD test run, and it’s miles ahead of the competition. 

Summary:

The Vertex 4 has shown that its performance is excellent, with the new 1.4 firmware performing even better than the original shipping firmware.
