This is probably the funniest statement in the post. But, let's go with that reasoning and avoid the TLC drive altogether then.

I just want to know if you will be a big enough person to admit you were wrong in a couple of years?
I think there are MANY people who are overreacting to the whole TLC lack of longevity specific to the Samsung SSDs. Some had a great deal of apprehension (which turned out to be unwarranted) when the transition from SLC to MLC was occurring.
I do not enjoy being wrong, but I am man enough both to hold my ground AND to admit when I was wrong. Only time will tell. Perhaps the truth lies somewhere in between. Even if that is the case, nobody is going to break the bank by choosing a Samsung 840 drive. whether it be an 840 TLC or an 840 Pro.
In the meantime, I am willing to spend my money with a company whose SSDs have built one of the strongest reputations for performance and reliability in the industry. The failure rates of other drives certainly shows that a crappy MLC SSD can have a weak link. There is no reason that proprietary technology could not somewhat enhance the life of TLC, just as poor design undermined MLC's
That is the great thing about having all the choices we have. If one brand or type of product does not suit your needs and another helps you sleep better at night, then by all means buy that product. Personally, I do not maintain any Pentagon secrets on my SSD, so if I were to buy a TLC drive and it went bad, it would not be the end of the world. If you are using SSDs for servers or other enterprise uses, by all means spend the few dollars extra and get the drive that makes you sleep better at night.
In the meantime, I will look for something other than a Samsung 840 TLC drive to hand down to the grandkids when I kick the bucket.

The truth is that the MLC used in the 830 not only has FAR better longevity than the TLC used in the (non pro) 840, it also has FAR better error resistance. TLC drives will have significantly more errors.
The speed differential between most SSD's is becoming nearly imperceptible to the end user. The differences are so minute they can only be seen in benchmarks. In a blind test, the end user would rarely be able to tell the difference.
The 830 has a last generation processor? The 830 has a 3 core ARM that comprises perhaps the most reliable consumer-grade SSD ever made. IOPS? Only enterprise users care about that. Most end users would be incapable of discerning the minute differences.
Given that the speed differences are nearly undetectable without benchmarks, the only remaining differentiators worth considering are price, longevity, and error resistance. The Samsung 830 bests the 840 (non pro) and all other TLC drives in the latter two categories. It bests them by a tremendous margin.
It may not be the cheapest, but it is far more reliable. Most SSD's are fast, not all of them are reliable. While not a great bargain at this price, it's certainly not a bad deal. For those that care about both speed and reliability, it's a very sensible purchase. I'd gladly pay this price if I needed another 256GB SSD.

There is a lot of nonsense being posted about TLC in this topic.
Longevity doesn't just matter in terms of how long the product will work before it stops allowing writes. TLC degradation can cause read and write speed to drop dramatically, increase latency, and increase power usage/heat production.
HardOCP estimated that not only can the 120 GB model fail in as little as 3.5 years of light usage, they found that even its read speed (the only thing TLC drives do fairly well when fresh) flatlined with use.
Longevity makes a difference, especially when we're dealing with ever-shrinking NAND which leads to shorter NAND lifespan. Right now, TLC is rated at just 750 P/E cycles. That is going to go even lower with the next node shrink.
There is no reason to choose a TLC drive when MLC drives are available on sale in the same price range. 19nm MLC is not expensive to produce, making TLC a solution in need of a problem.
And, the 830 is much better than the 840 TLC.

I have stated it before that if you're an enterprise user this is a good price on this drive. I even recommended spending $20 more on a drive, the Plextor M5P (5 year warranty vs 3 year on Samsung 830) which is now listed in another thread for $190 using V.me from newegg:

IOPS are irrelevant when it comes to TLC vs MLC comparison.
It almost appears as Samsung is trying to make a few quick bucks by catching people with lack of knowledge and great desire to have the latest, not necessarily the better, when it comes to 840 series (not 830 or 840Pro).
TLC vs MLC ? TLC by nature of its design should last only 3 times shorter life than it's MLC counterpart. It's a matter of memory cell longevity, that's all.
So, perhaps one should ask himself if they want to pay 30% less $$ for a Product that only will last a 1/3rd (300% less) of the usual lifespan.
Toyota and Scion? There is a brand name difference, it's not like Toyota cars are made of metal and Scion of crumbling plastic. Not sure the relevance of the earlier comparison.

My point is that to the average consumer(and his usage) the performance or reliability differences between the 840 and 830 are completely irrelevant, rendering comparisons not related to price moot. If you're using the SSD in such a way that 80,000 IOPS or 500MB/s matters to you(multiple virtual machines, etc) then you will obviously go with the 830 or 840 PRO instead of the 840, regardless of the price.

For my uses (and maybe many other users) I doubt I can wear out the estimated life expectancy of the TLC drive. With that in regards I'd rather choose the Samsung 840 given the improvement in speed that would benefit me more.

In a nutshell MLC lasts longer than TLC memory, however many don't factor into consideration the controller that's being used. Similar to how all manufacturers produce MLC drives but they're not all created equally.
To me I have had MLC drives die on me, sure the actual memory may last longer but what good does it do if the drive just die? Nothing. This can happen to any drive, I have yet to hear a TLC drive die from normal use (that's because it's still fairly new).
