Reading Benchmarks

HD Tune Pro

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

From our limited number of test samples, we can clearly see the OCZ RevoDrive X2 series SSD is very fast; in fact it’s the fastest reading drive in this test by a long way.

ATTO disk benchmark

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

The reading speed results on the OCZ RevoDrive X2 are extreme, topping out at over 823MB/s, writing speeds are extremely impressive topping out at 698MB/s. ATTO writes its test data in a format that can be compressed by DuraWrite, so you are seeing reading and writing in a best case scenario, but certainly shows what these four SandForce SSD controllers are capable of doing.

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.

While ATTO shows the SandForce controller in its best light, Crystal Disk Mark uses test data that isn’t so easily compressed by DuraWrite, therefore read and write speeds are not quite so high, but extremely impressive in any case.

AS SSD Benchmark

AS SSD benchmark is a new benchmarking tool, specifically designed to test SSD drives. 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 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 RevoDrive X2 in the form of a screenshot. All our other comparison drives results are presented in the form of a graph.

Given that AS SSD benchmark writes a lot of compressed data in its tests, the OCZ RevoDrive X2 is still at the top of the tree by a long way. Threaded performance is particularly strong, which I’m finding is a key factor in real world performance.


The sequential reading speeds on the OCZ RevoDrive X2 series SSD are excellent and this is the fastest drive we have ever tested here at MyCE.com. Sequential writing speeds were also the highest we have ever encountered here at MyCE.com, and the same applies to the 4k random write.
