Real-world results often differ from synthetic test results, so we developed a couple of tests to simulate how you would really use an SSD; copying and moving files, and zipping and unzipping files.
We timed two different file-copy operations on each drive. In the multi-file test, we copied 4.97GB of mixed-media files from one folder to another. In the single-file version, we duplicated a single 3.1GB file.
|Drive||Multi-File Copy Time (sec)||Single File Copy Time (sec)|
|Samsung 830 Series (256GB)||25.3||13.0|
|Intel SSD 510 (256GB)||30.0||15.7|
|OCZ Vertex 3 (240GB)||32.3||23.0|
|Patriot Wildfire (240GB)||37.3||25.7|
|Samsung 470 Series (256GB)||49.3||24.0|
|Hitachi 7,200 rpm||137.0||71.7|
Samsung’s 830 Series drive owned the competition in our file copy tests, beating its nearest competitor, the Intel SSD 510, by 15 percent in the multi-file copy and 18 percent in the single file copy. The two SandForce-based drives trailed by a wide margin. Due to its lower-bandwidth interface, the SATA II drive was also significantly slower.
We further taxed the SSDs by zipping 4.97GB of mixed-media files and then unzipping the resulting archive.
|Drive||Zip Time (mm:ss)||Unzip Time (mm:ss)|
|OCZ Vertex 3 (240GB)||2:47||2:25|
|Samsung 470 Series (256GB)||2:58||2:28|
|Patriot Wildfire (240GB)||3:11||2:27|
|Intel SSD 510 (250GB)||3:24||2:17|
|Samsung 830 Series (256GB)||3:24||2:23|
|Hitachi 7,200 rpm||3:25||3:32|
When it comes to archiving, the OCZ Vertex 3 is king, taking 24 seconds less than its nearest SATA III competitor to build the ZIP file. Surprisingly, the SATA II-based Samsung 470 series actually built the ZIP faster than its SATA III successor. Intel’s SSD 510 offered a slightly faster extraction speed than the Vertex 3, but OCZ’s drive offers the best overall mix of performance on both tests.
