Confused about modern Samsung 830/840 comparirisins

[Cyber_Akuma]

When I built my PC in late 2012, the Samsung 840 was just coming to market and the 830 was being replaced everywhere.

At the time, there was debate if the 830 or 840 was better, but most seemed to agree the 830 performed better, and the 840 pro was too expensive.

Looking at SSDs now, I see the 840 EVO, I assumed this meant it was the cheaper/more economical model, but then I saw this comparison chart:
http://ssd.userbenchmark.com/Compare/Samsung-840-Evo-250GB-vs-Samsung-830-256GB/1594vs1387

And it completely and utterly blows the 830 away.

Ok, fair enough, I assumed that since its two years newer it would had to have some improvements by now, even if its the more economical model, but it seems almost ridiculously faster.

Then I compared the 840 evo to the 840 pro:
http://ssd.userbenchmark.com/Compare/Samsung-840-Pro-256GB-vs-Samsung-840-Evo-250GB/1408vs1594

And to my shock.... it's actually worse than the EVO by a little bit.

Ummm... huh? As far as I know, the PRO is still being made too, and costs much more than the EVO. Is this site just completely inaccurate?

The 840 Pro is an older design than the 840 EVO, but is still very fast. The Pro line is supposedly supposed to be be from better binned components, and has a 5 vis a vis a 3 year warranty.
