How long do SSD's usually last?

[SyferOnline]

Was wondering how long a SSD and a NVMe SSD both last? I'm currently working on a PC and I wanted to use a normal 1TB SSD as the HDD. I already have which SSD and NVMe SSD I want to buy, just don't know how long these things last.

A very long time in consumer use, as you can see from studies of earlier drives HERE and the killer study HERE.

I have an old Intel X25M 80GB that is a video caching drive that has almost 100TB written and going strong.

For the Samsung 850 Evo assuming you write 20GB a day it will officially last 187 years. Up that to 100GB a day and it drops to 18.7 years. The 850 Evo uses inferior TLC NAND. MLC ( Pro drives ) lasts longer.

The computer it connects to will be obsolete long before it wears out. 😉

Years and years and years.

Generally, a number you might see, in the warranty or elsewhere, is TBW. Total Bytes WRitten.
Current drives generally have a warranty of 75 or 150 terabyte lifespan. Or 5 or 10 years, whichever comes first.

"OMG!!! They have a limited lifespan! It will die next week!!!"
Yeah, not so much.

So, out here in the real world, 75TB is actually way more than you think.
My previous boot drive SSD, a 120GB Kingston, had been in almost 24/7 service from Summer 2012 to Summer 2016. In that timeframe, there was a total of 12.8TB written to it. ~3TB per year.
(I'm getting ready to put this same Kingston in another PC)

Extrapolate that out, and that gives a theoretical 25 years before it hits that 75TB life.

But wait....just like parts usually last long beyond their actual written warranty, SSD's do as well.
Here is an endurance test where regular consumer grade SSD's lasted well above 1,000 TB written (1PB) before they actually died.

Extrapolate that out, and your great grandchildren could, in theory, be using these same drives.

Of course, just like any bit of electronics, they can die. No different than a monitor, or HDD, or your phone.

Bottom line...SSD's are no less reliable than a regular HDD, and probably more reliable.
It will not die anytime soon. It will become obsolete due to size long before it dies from too many write cycles.
