Early last year the company caught the SSD market by surprise with the release of their 830 Series SSD, which was followed in late 2012 by the 840 and 840 Pro that provide awesome performance and focus not only on performance, but also on reliability and long-term performance stability.

So the big difference in terms of performance you can likely trace to the flash memory in each drive.
