Re: How long will my (your) SSD last?

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.

Which gives me more hope on my Vertex2 and more anecdotal evidence against the OCZ nay-sayers.

Pretty sure my current linux box was built around 2003 or so. Same hard drives in it as when it was built.
