Re: How long will my (your) SSD last? Yes, there's that possibly but again it all depends upon how many writes you are making to the SSD.
The point of my post is that a lot of enthusiast web sites seem to be so focused on the lifespan of the SSD. They all seem hyper about it to the point that even the mere thought of having even the slightest reduction in SSD lifespan (even theorized reduction) can make these people not want to buy a particular SSD. The thing I'm trying to drive home is that for the average home user with their average computer with average use (and that even includes us geeks here on this site), an SSD will outlive the usefulness of the SSD in the sense that we'll be looking to buy a new one for increased capacity long before the drive dies from too many writes.
So go ahead, buy the SSD. Don't worry about that number. All of the enthusiast web sites seem too focused on that number.

| I use the SSD as the primary boot drive. I have two of them, one in my desktop and one in my notebook.
Getting an SSD, especially one of the cheaper drives such as the Samsung 840 Series (non-Pro) really is one of the best (and cheap) ways to upgrade an older computer and make it feel like new again.

Hmmm....can't see why I'd be looking, during the lifetime of this computer, to buy a new larger one when I have a Samsung PM830 mSATA 256GB drive.  I don't know if SSD Life is any good at determining the life of this drive but it claims 8 years, 5 months.

I got a Vertex 4 512 gb over the summer. I reinstalled Windows 7, and I hacked the install procedure so that my "C:\Users" directory pointed to my existing hard drive; everything else on SSD. I figure that that directory is responsible for most data writes and doesn't need to have super fast times, so my SSD should last longer.

Not sure what the huge fuss about SSD life is all about...
I have one in each of my computers as a boot drive (the one in my laptop is my everything drive). I recently built a PC for a friend and here's the way I look at it:
For a consumer grade drive (for a desktop), 120GB - 128GB is sufficient as a boot drive. That'll set you back about $100 (Samsung, can't remember the model). The difference between the i3 and i5 CPUs we were looking at was about $100.
So if you're looking to spend that $100, is an SSD more beneficial than an i5 for an average consumer machine?
That $100 will disappear quickly in the CPU as more powerful CPUs come out, so who cares if the SSD lasts only 5 or so years, isn't the speed increase worth it?
My friend is amazed by the difference the SSD made in his machine. Pretty much instant on (in Windows 8) with very good performance. That machine will get a mid cycle CPU upgrade ($50 on eBay in a couple of years) before the SSD needs any attention.
I know that my 2.5 year old i3 370M SSD performs better than my wife's 4 month old i5 HDD(cant' remember which CPU, 3rd gen though) laptop. For the base level SSD's, there is value. I would be more concerned about spending $400 on a 512GB drive, but at the 256GB and less ($200 or less) level, a few good years is all I ask. |

said by aurgathor:The SSDs I wrecked accumulated bad sectors, so in a real life usage that could've meant some data loss, the exact amount depending on the number of bad sectors and on their location.
In those cases, once the SSDs reached a certain limit, they wouldn't boot any more, Win8 would enter into an infinite repair cycle, etc.
So the big question in that case is - will freezing the SSD drive allow you to recover data which has not been backed up?
Freezing a failing/failed mechanical drive for 24 hours often is enough to get get it working to the point where you can extract data for 15-20 minutes until it really warms up again. |

All depends on the writes to the same NAND cells so to speak. More writes to the same spot will kill the drive faster. I was thinking of using one in a pfsense box until I started looking at the logging system. I figured I would have killed the drive in under two years in that setup. |

SSDs are very different, and what you can do with a failed SSD depends a lot on the failure mode. You need to forget about freezing and think about something else.
If there are worn out cells there's probably not much that can be done to retrieve data from those -- at least partial data loss. This can be a result of an end of life wearout, so this is a normal failure mode that will happen sooner or later unless the SSD is replaced. Given that in normal usage SSDs are expected to last 10+ years, they're likely to be replaced due to small size and/or obsolescence well before cells start wearing out en masse.
If the whole flash chip bites the dust (i.e. ESD damage) for all practical purposes, all data on said chip is gone -- that means at least a partial data loss, but if the flash chips are interleaved for higher through put, it can also mean complete data loss.
If the controller chip bites the dust, in theory it can be removed and replaced and the SSD should be fully functional with the data intact. Note, "should" doesn't mean "will", and replacing BGA chips is not easy, to say the least.
If it's a firmware bug (as was the case in the SSDs I wrecked) the result depends on many things and it can vary from total loss to full recovery.
Due to the lack of moving parts, I consider SSDs more reliable than MHDDs, but if you have valuable data, you should keep a backup, no matter what.

Thank you everyone. This is valuable information, and thank you for dispelling the myth of premature failure. I, too, fell into the trap of listening to naysayers of how they will fail quickly. From all the info I've just read here (and seeing the uploaded stats), I surmise getting an SSD for my laptop (and possibly desktop) would last a lot longer than I thought otherwise. This is good news.
I was looking into replacing the SATA drive for an SSD on my Latitidue D830 and use the DVD drive bay as an extra hard drive, since I don't use the DVD burner that much. Now, if only I had the money to buy me an SSD.

This is pretty much how I did my Inspiron E1505. SSD in the main HDD slot and a larger HDD in the optical bay with the proper adapter. Works a treat. And thanks to Win 7 and 8 being easy as pie to install from a USB flash drive, lack of a DVD drive should not be an issue. 
Should note that SSD's are becoming increasingly cheaper. My 60GB OCZ Solid3 I bought October of 2011 cost me around $125. These days you can get the same for around half the price or a 120-128GB for the same price.

Myself, I'll probably upgrade the SSD to a larger capacity SSD in three of so years. Programs get bigger, drives get faster, latencies get lower. All of these are reasons why in a few years you're going to possibly want a larger SSD. It's like anything, things get better.
I have a 250 GB SSD and I use it for a lot of my programs for instant boot and instant program launch. Things like web browsers and utilities get installed on the SSD. Games are installed on the HDD.

said by koitsu:said by cpsycho:All depends on the writes to the same NAND cells so to speak. More writes to the same spot will kill the drive faster. False. *sigh* Right. Firmware will prevent you from writing to the same block repeatedly. This is the function of wear leveling and garbage collection.
The SSDs currently in the market uses BCH for error correction. When the NAND flash gets "worn" out, there would be increasing raw read errors; when the point is reached where the correction power of BCH is exceeded, the user will start seeing uncorrectable read errors.
The next generation controllers for SSD will use LDPC for error correction. LDPC can benefit from soft information which can be generated by performing multiple reads with shifted read reference voltages. It is expected that controllers with LDPC will prolong the life of SSDs when used with TLC NAND devices. |

I have owned two OCZ Vertex drives and they both failed within hours of installation . I replaced with Intel 520 series, which is still working one yeat later.
In the past month, I bought two Intel 335 series drives for two WIN 7 installs. Am very happy with all of the Intel drives so far. They work and are fast, ad well as run cool. |

said by koitsu:It depends on how the vendor chooses to implement storage of the SMART attribute data. For example, on some (not necessarily all) Intel SSDs, attributes 241 and 242 RAW_VALUE columns track the number of 32MBytes (more specifically 32MiBs) read/written. Use smartmontools, it has proper decoding for this. TY. Then it looks like OCZ is correctly displaying the conversions. I compared the smartmontools output to what OCZ Toolbox and it works. Thx again. My fuzzy math sees 349days of 2.56GB writes daily and 12.65GB reads daily. It'll take me a minute or two to get to 100TB writes
