SSD Wear Levelling: Is a bigger size of SSD better?

Would investing in a 2Tb SSD give me a longer life expectancy in terms of wear levelling than compared to a 1Tb SSD? Am I correct in thinking that as a 2Tb has more space over which to spread the wear levelling, it will (in theory) last longer?

My usage will be mostly documents, photos (quite a lot, around 100Gb) using Lightroom/Photoshop and downloading/watching videos, but I will not be doing 4K video processing, 3D modelling, high-end gaming or anything intensive like that.

Is it possible to estimate the expected life expectancy for a 1Tb SSD?

Any help/advice would be appreciated on whether a 1Tb or 2Tb SSD would be the best purchase option.

Thanks in advance.

For either of those drives, the lifespan due to wear leveling is measured in decades.
Unless you are using if for a transaction heavy database, it is not really a concern for any SSD of 250GB or larger.

Yes, in theory a 2TB drive will last 'longer' than a 1TB. But that is like the difference between 50 years and 52 years.

All my systems are SSD only. 8 drives in size from 120GB to 960GB.
The 120GB Kingston being the eldest, at almost 6 years old.
They are all at 99% or higher lifespan remaining.

The SSD, if it dies, will die of something other than too many write cycles.

The Larger drive will give you more TBW (Tera byte Write) because it uses double chips on the Board (if the series is the same)

look for the TBW specs in the SSD , not the size of the SSD .

and dont worry much , The drive will fail from other reasons before failing from TBW is reached ... unless you fill it up and delete it on daily basis which no one does.
