Reading Benchmarks


HD Tune

HD Tune – Sequential reading test

I present the graph below for comparison with other recently tested drives.

The OCZ Octane performance was extremely impressive with an average reading speed of 513.2 MB/s, but what is even more impressive is the incredible average access time of only 0.039ms.


ATTO disk benchmark

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

The reading speed results on the OCZ Octane series are extremely impressive, topping out at over 475 MB/s, writing speeds are not quite so impressive as the reading speeds, but still top out at over 316 MB/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 Octane 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, 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 Octane series in the form of a screenshot. All our other comparison drives’ results are presented in the form of a graph.

The OCZ Octane 512GB SSD finishes in fourth place overall, and is well behind the OCZ Vertex 3 and the Crucial C300 and M4. However, just look at the read/write access times, which are excellent and will prove to be the key factor (amongst others) that allows the OCZ Octane to outperform the big guns from SandForce and Crucial in many of the real world tests, which will appear a little later in this article.

Summary:

It’s a mixed bag. The OCZ Octane series SSD is fast, but can’t compete with the OCZ Vertex 3, Crucial M4, and C300 with small file random write performance. However, sequential performance is excellent, and those incredible read/write access times should provide for some very interesting reading later in this article.

Synthetic benchmarks don’t lie, but they only show what an SSD can do technically when it’s pushed very hard, and this has very little relevance in a normal user's desktop PC, as we will see later in this review.
