Benchmarks: File Copy Test
For our 6GB ISO test, we take a single large file and duplicate it on the disk measuring the time it takes using a stopwatch. The test is run three times and the average result is recorded. Generally, all three runs are pretty much identical. The above graphs show both transfer time in seconds and throughput in MB/s.
We typically find that SandForce based SSDs, such as the Vertex 2 Pro 100GB, really struggle with this test as we are working with a large compressed file. As you can see, the Vertex 2 Pro 100GB is no faster than the older Vertex 120GB.
However, the OCZ RevoDrive X2 240GB was 3.4 times faster than the Vertex 2 Pro 100GB, taking only 25.7 seconds to complete. The Samsung 470 Series and Crucial RealSSD C300 represent the fastest MLC based drives we've tested, and both of took more than twice as long.
The completion time of 25.7 seconds translated to a throughput of 232.4MB/s, which is staggering compared to the Vertex 2 Pro's 67.4MB/s and even the 114-115MB/s throughput of the Samsung and Crucial drives.
The program copy test is comprised of many small non-compressed files. This is where SSDs often struggle, and early-gen drives have proven to be slower than traditional hard drives in the past. Our reference Samsung 3.5" desktop hard drive managed to complete the test in 28 seconds making it a fraction faster than the Seagate Momentus XT 500GB.
The OCZ RevoDrive X2 240GB takes just 6.1 seconds, making it roughly twice as fast as the Samsung and Crucial drives. Compared to the OCZ Vertex 2 Pro 100GB, the RevoDrive X2 240GB was 3.1 times quicker. Again we saw a sustained throughput of 232MB/s, while the Vertex 2 Pro 100GB managed just 73.7MB/s.
The game copy evaluation is comprised of a mixture of small and large files. The OCZ RevoDrive X2 240GB completed this test in a blistering fast 5.1 seconds, again making it twice as fast as the Samsung and Crucial SSDs. It was also 3.6 times faster than the Vertex 2 Pro 100GB with a total throughput of 268.9MB/s.
