Samsung 840 EVO or 840 pro seem to be the best at the moment.

what about some sources when telling people stuff like this
not that i know what i am talking about, but. that article you linked is VERY VERY short, with no testing results to back up the claims,

I'd rather base my opinion on this tbh;

Its not an article, its an entry in an encylopedia. They usually don't post test results. I see your point tho and I will make the argument, that this is just how NAND Flash works: It is proven (I'm too lazy to find a link, but you may always use google yourself) that NAND Flash Cells can survive only 100,000 delete cycles if they're used as single level cells. They can survive 10% of that (10,000 delete cycles) when they're used as multi level cells (two bits are stored in one flash cell, this is achieved by storing the information as one of 4 possible voltage levels). And Triple Level Cells can survive another 5% of that (500 writes approximately, depending if the controller stops writes earlier). This is because there are 3 bits stored in a single cell, represented by 8 possible voltage levels. This requires some serious IO logic and because the way flash cells work (isolating an electric charge by means of quantum tunneling) it degrades the physical cell more than it would for mlc or slc respectively.
And even if it was 1000 writes, if you are downloading a lot of stuff, or watch tv shows and movies on the pc when this drive holds the temp folder, you will get to the 1000 writes (or 500 writes) relatively quickly.

You do have a point. Yes, the 840 Pro is more reliable and will theoretically last longer. That doesn't mean that the Evo will be dead in 6 months.
Samsung offers at least a 3 years warranty on them, so you can safely assume they're going to last longer than that, otherwise it would cost Samsung money. Then, depending on how much exactly you're going to use it, it can last even double that, maybe even 10 years.
There is just literally no way to tell how long one will last. That's like predicting an overclock of a CPU chip that's running at stock. It's a win or lose thing I guess, but that's the case with any SSD, even the 840 Pros.
If OP has the money, then yes, I'd recommend him the Pro, but the Evos offer really nice speeds (and still reliability) for the money, and that's what this thread was about.
If he plans to use it for storage of files that are written and removed a LOT, or re-installing windows or big programs multiple times (for whatever reason, lol) then yes, 840 Pro is probably the way to go. Truth is that most people use their SSD to slap Windows on it, as well as some apps/programs that they use a lot or that benefit from the SSD, and for that, the Evos will be more than fine

jeez, my head just exploded reading that!!
but as feronix said, it is gonna last a while anyway. (longer than an ocz ssd anyway!!)
Funny you should say that because my 3 year old OCZ SSD is still working 
I am however not writing anything on it, if I can avoid it
If you aren't writing a lot on the SSD, you should be fine, but if you want to do photo-/video editing or something write intensive, I would go for a MLC SSD.
@Feronix: Well, they can give a 3 year warranty because they can produce so many, so cheap and can thus sell many, they probably have their sale-price adjusted so that they could cover quite many RMA'd SSDs. Of course those will be less than lets say 20% of the ones sold, because the ones not RMAd may have not been used very intensively, but don't think for a second, that a 3 year warranty means that the product will work guaranteed for 3 years
Maybe I'll buy the smallest possible 840 EVO here, put it in a case, plug it in my raspi and let it write all day, delete when its full and write everything again and let the program log and count how many (complete) writes it has done and post results...

Not to hijack the thread in anyway....
But when you guys say "500 writes", you mean 500 x 256GB(if the ssd is 256gb) right?
So you fill the WHOLE ssd and delete the WHOLE ssd 500 times before dying.

Yes wrenaudrey, 500 times the whole SSD.
This means that theoretically, my 60 GB OCZ Vertex 2 is more durable (as in the amount of data that can be written before the delete cycles run out) than the 1TB 840 Evo
In reality this isn't the case because OCZ put a shitty controller on the SSD and has used generally low quality components, but its food for thought.
