All of the SSD's tested have exceeded 500TB of data written to them without any major problems.
(Edit: The Samsung 840 briefly had some issues with corrupt data around the 300TB mark. It seems my brain may have had some similar data retention problems. Thanks for pointing this out rui-no-onna.

500TB works out to 140GB of writes per day for 10 years.
In short, I will never be worrying about "wearing out" my SSD.
The talk about the Samsung 840 drive reallocating sectors means that some sections of its memory have worn out and can no longer be written to. When this happens bad sectors are no longer used and the drive instead uses memory in its section of spare memory. The spare memory is extra memory that the user can't see or use. This means that the drive can replace sections of its memory without any effect on the overall capacity.
Once all of the spare memory is used up....I have no idea what happens. It will be interesting to see how windows and the Samsung's firmware handle the problem of the drives usable space shrinking.Edited by jason793 - 1/14/14 at 7:39am
