There are already budget MLC drives. MLC at 19nm is not expensive to produce. TLC is a solution in search of a problem. Worse than that, as NAND shrinks, P/E lifespan is reduced. So, why compound that problem further? HardOCP found that the 120 GB drive's read performance flat-lined. The larger drives may hold up better for mainstream consumers, but the higher power usage still makes one ask why choose a TLC drive over a budget MLC? |

in that case..

Beware of this SSD. I've already gone through 2 already due to random file corruption that would BSOD with STOP 7B message on a Windows 7 machine. Cloned the original drive to an M4 and no more corruption issue.
There's a reason why you can't even do a warranty service request on the TLC/840 unit on Samsung website. I wonder why. Go to http://www.samsung.com/us/support...ce/request hit Find then Office > Memory Storage > SSD. Only the MLC/840 Pro and 830 are listed. TLC/840 units are not listed on there. TLC/840 model number starts with MZ-7TD |

I think the Wiki is misleading.
Performance wise, if someone is going from a HDD to an SSD, there will be a huge jump. It's like going from a Ford Taurus to a Lamborghini Aventador. The 840 Pro will be considered a McLaren F1. Does nitpicking on each spec really matter if you had the Aventador or the F1? Would you not be just happy that you have a car that does 0-60 in less than 4 seconds. If one car does it in 3.2, and the other in 2.8? Also, it'll take a few years before the drive even caps out its lifecycles. I believe the reviews mentioned it to be around 5-7.I wouldn't worry about these reviews too much and at $140 I'd jump on it had I not bought the 840 pro at $199. At $140 this is a heck of a lot better deal. |

I bit on this one and I'm replacing my 5400 rpm with this. I'm hoping the difference will be pretty noticeable. Also, this is a really good deal because I've been waiting for a good 7mm ssd to come up since I have a samsung ultrabook that only has room for a 7mm drive. So, rep to the OP. |

The problem you guys aren't realizing with the TLC vs MLC (840 vs 840 Pro) is that it doesn't take into account the cost/size of the drive.
For example, due to wear leveling and write amplification, a very high capacity TLC drive offsets the lower writes. If you can afford a 240g TLC or 120 MLC I'd take the TLC all day long for the daily user. The fact that you have more than twice the memory give you the ability to make more that 2X the theoretical writes beyond the rating each individual cell gets. If a 120 is fairly full, the remaining cells will get thrashed pretty hard, even with TRIM. If you have another 120 free, even with a TLC drive, it can spread it out over a LOT of cells. TLC isn't as bad as it looks on paper for average consumers. In SSDs, unlike HDDs, speed and longevity are also tied to the size, and cheaper processes like TLC help increase size. |
