While it would be nice if Samsung made a more clear distinction between the technology underlying the 840 and 840 Pro, most of the negativity on the TLC NAND the non-pro variant uses is hyperbole. Disclaimer: Owner of 1x 840, 2x 840 Pro, 4x 830, and 5x Intel G2/G3 SSDs. |

You guys saying that TLC is good enough may be right for yourself. But I wager I do not use my drives the same as you do. I have written 4 Tebibytes of data to a single 80 Gigabyte Intel X-25M SSD over a few years. And the drive averaged three quarters full while I did all that. So that leaves 20 Gigabytes of actual space heavily written to for all that.
4,194,304 MB / 20,480 Mb = 204.8 writes average per cluster/sector. I really doubt the TLC drives *ALWAYS* exceed the claimed 750 writes they are supposed to be good for. And one single failure means a hard crash and lost data, or at best a bad cluster and file system repair work along with a S.M.A.R.T flag on the drive for the failure. Let us think of this another way. There are 750 sandwiches in front of you. One of them has hydrogen cyanide mixed in. But they are really cheap. You never know if the next bite will be excruciatingly painful and lethal, or just a good sandwich. Would you bother or would you pay a reasonable price that is just a tiny bit more to be certain it will be a good sandwich? Honestly there are many factors to consider on this thing. Far more than my simplified example touches upon. But this deal is awful. If you like it, good for you and I hope it works so well that I sound like a paranoid fool. Be well everyone. |

Anand didn't run the drive until it was dead. When you do that you get 443 terabytes [xtremesystems.org], if you're writing 20GB/day that will last you 61 years. If your plans are to be using this drive in 2074, more power to you.
Note that was a 120gig, a 256 should last significantly longer. |

even though I am tired of seeing this drive on FP every ****ing day, I think this deal deserves it IF you want assassin's creed 3. If I was a fan, I would buy it in a heartbeat considering the game alone retails for 50 bucks. that makes this SSD 100.00 which is awesome.
Fortunately for me, I dont buy games until steam has them on sale for 5 bucks (lol), so this is still not an FP worthy deal (for me). On a side note, I've been using the OCZ vertex 2 64gb on my macbook 2006 since it was released (I paid 150 for it, OUCH!)... its given my laptop new life, and zero problems since I've had it. Bottom line, for the budget conscious person that needs an SSD to give new life to an aging computer, or only uses their pc for word processing/web browsing... buy the cheapest SSD you can, regardless of brand, as long as there arent too many negative reviews about reliability/firmware issues, and you won't regret it. |

Seems like there's a slickdeal on a Samsung SSD every week. This isn't even newsworthy anymore cause there will be another deal along in a week or 2.

http://www.tomshardware.com/revie...24-11.html The other article i read said roughly 8 years MTBF in average home use: http://www.anandtech.com/show/573...ssd-review I did some reading a few months back after the Kingston HypberX 3k model meaning raised my hackles. Those 2 articles put me at some ease. Plus i've had a laptop with an Intel X25 80g in it for just over 2 years. Running the Intel tool shows 100% health yet, and I use it daily, games, surfing, light business use, etc. We'll see in a few years i guess, Since 4 PC's and a laptop in our household are now booting off Intel X25 or 320's and Samsung 830s and my gaming rig has the HyperX 3k for Steam games. I dunno about getting 7-10 years out of it, but i'd be lucky to do that with platters. I'm probably approaching 6 years with some Samsung 80g satas in daily use at home, but most have been taken out of service in favor of SSD's. And I do have two 20gig IDE WD's in an old dual 733MHz server from back in the day, probably over 10yrs each. But, they are only powered up a few times a year to archive some stuff, identical on each, and then shut down. |

I've used mine in a virtual 24/7 power on system for about ten years, granted it's probably 95% idle time but I still think that's pretty phenomenal for hard drives... |

They were commenting specifically about the 120GB drive; this is a thread about the 250. At any defined GB/day write specification, the capacity of the drive (and write amplification factor) is critical to determining its durability. HardOCP seems to be assuming a near worst-case (and unrealistic) write amplification of 10 to get those figures on a 120GB drive. Anandtech's review and special statement on TLC endurance is probably more realistic, estimating just under 12 years of life for typical usage on the 120GB version (over 23 years on the 250GB) until the wearout indicator hits 0--which doesn't mean the drive is dead. Most drives far outlast the 0-life-remaining indication. Again, that's the 120GB version, but even HardOCP's review has the following sentence in the paragraph just after the one you quoted (emphasis mine):
Nobody is suggesting that this is the best SSD on the market or that it is even in the upper tier. However, this drive will perform better in real-world usage than any mechanical and it only falters when compared to the latest generations of top tier SSDs. I'm not sure that you fully appreciate the point of this drive. What this SSD will do, eventually, is bring prices at its capacity points to levels unattainable by MLC. I believe that this drive represents the next phase in the push to finally bring solid state technology to the masses. It's still fairly new, and is already hitting price points as low or lower than even late runs of the last generation of drives. That is a very good sign. You don't like this drive and that's entirely your right. Nobody is forcing you, or even asking you, to buy one. I simply ask that you stop making this drive out to be the boogieman for those looking to SSDs for the first time. So, |
