Re: How long will my (your) SSD last?I use my work laptop pretty heavily and I'm only up to 1.94 TB after about 14 months.
Intel's documentation for the Intel 320 says it is rated for 20GB per day for the full 5 year warranty. That's about 36TB.
That's probably conservative too, 25nm NAND is supposedly good for 3,000 write cycles. Assuming a write amplification of 1.1 that seems to be about 320TB for my 120GB drive. If it was the 480GB unit that number would be over a PB!
It's not even close to a concern yet unless you are moving crazy amounts of data. Someone who does heavy HD video editing might be able to comment on how long it would take them to write something like 100TB of data. |

I did some fuzzy math here.
My SSD has been online for 694 hours. 694 hours / 24 hours = 28.9166 days
I have written so far 556 GBs to the drive in those 694 hours.
So for the sake of this math, I'm going to say that in the average month I'm going to write about 700 GBs per month.
100 TB = 102,400 GB
102400 GB / 700 GB per month = 146.2857142857143 months (or 146.29 months)
146.29 months / 12 months (1 year) = 12.19 years
So, if an SSD can sustain 100 TB according to the test so far, which we can't say is the limit since the SSD hasn't died yet under TweakTown's test, we can therefore say that an average Samsung 840 Series 250 GB SSD will last anywhere from 10 to 12 years with a sustained write of an average of 700 GBs per month.
Or, if you do an average of 800 GBs per month... that's going to be the following math.
102400 GB / 800 GB per month = 128 months = 10.66 years.
So that means... an average of 9 to 10 years of life. |

I've had my Vertex2 powered on for 13,328 hours (555 days) and done 18.69 TB of reads and 5.00 TB of writes. |

It doesn't need to last forever, just long enough.
How many people are still using a computer, much less a hard drive from 2001-2003?
Even my extreme technophobe grandmother (Who barley uses a computer at all) shed her 1999 HP win98 machine almost 6 years ago. |

What I'm trying to make with my post, and granted, I am probably preaching to the choir here, is that the fears that TLC and cheaper NAND flash in SSDs is really nothing to worry about.
Most SSDs, even the lowly Samsung 840 Series (non-Pro) is going to last the average consumer, even us geeks, longer than we will ever want to keep that SSD around. Chances are, that SSD will end up in the recycling pile in exchange for a higher capacity SSD long before it's dead. |

Note, this is based upon the life of the NAND flash memory itself. This observation does not take into account possible firmware issues that may cause premature SSD death. This is something that can't be predicted. |

I do some video archiving in my personal time and so far my Ocz vertex 4 has done 4.48 TB in the 93 days ive owned which comes out to around 48 GB/day. So it would take me around 5.7 years to get to the 100 TB mark. |
