The Intel 330 is a very good and stable SSD but it is not the fastest on the market.
Most people look at only the Max Sequential Read and Max Sequential Write speeds (500/450 MB/s for your drive) when buying a SSD, but an SSD's 4K Random Read and 4K Random Write is more important for what the majority of people use their SSD for.
Most Windows files are in the 4K range and I wouldn't be surprised if most games files were too.
The 4K Random Read speeds for your drive are up to 22,500 IOPS. The 4K Random Write speeds are up to 33,000 IOPS.
Compare that to the 128GB Samsung 840 Pro which has 97,000 IOPS Read and 90,000 IOPS Write.
