Madshrimps purchased a 30GB OCZ Vertex SSD and published some benchmark results, you can check it out over here.
While all those benchmark charts displaying 200+mb/s read and 150+mb/s write are impressive to see, it's also good to actually have some idea of what that extra performance brings you in real life. We prepared two identical laptops with Windows 7 and Windows XP, one had a conventional HDD, the other a brand new OCZ Vertex SSD. The result is worth checking out.
The article contains several videos, including this one where the reviewer compares the Windows 7 bootup time plus launch of some random applications on two identical Dell Latitude D630 systems; one with a Hitachi 80GB 7200RPM HDD and another one with the OCZ Vertex. The system with the SSD finishes loading in 39 seconds, while the notebook with the HDD takes more than 2 minutes.
