Looks like 980pro isn't very PRO compared to WD Black Sn850


in past samsung PRO SSD is about extra endurance rather extra performance
970 pro is 2x endurance 970evo at same size , right ?

but their 980PRO model position is kinda messy
its rated-endurance is same to 970evo (1TB = 600TBW , 970PRO 1tb is 1200TBW)
not sure if it only warranty terms or not

Yeah there really is no "pro" line anymore other than in name.

case by case, for end-user such gamer probably is, but not everyone
and thats why EVO & PRO segment different, EVO should fit for most people, as they most likely wont used up ssds endurance within 5years

but if like u saying, what for those enterprise SSD with high endurance rating ?
u might say servers is different than pc, well yeah pc usage can also different from one use to another
such workstation that doing high write, those will still get benefit from higher endurance or even need it

cache as by its function, only storing some of the bits, it wont cache everything u dump into ur SSD
for example 1TB 970 evo SLC cache is 6GB dedicated and 36GB dynamic? cmiiw
it shave some writes, but if u writing like 200GB+ data everyday (rendering, movie editing), or transfer/download tons of data, it still doing many writes to nand

in most case with SSDs, you start encountering errors when u reach rated-endurance
and thats why the warranty terms which is 5years (for samsung SSDs) or rated-endurance (TBW)
in this part its not so different to traditional HDD

The average user will never use 200GB a day, let alone 50GB a day or even a week. Going by that logic, you'll be on a different SSD in 5 years time or a completely new technology by then.

Don't worry about endurance too much, unless you're working in enterprise.

I would easily reach 50 gb a week, daily ? No not often. On the other hand in general in this forum most of us are definitely not average users :p so worries about endurance if there is a place for em to be realistic it is here ! About me now i would feel just fine with a qlc drive for a steam library but i will avoid it for os drive .

Endurance is one of the main reason why Samsung will always be superior to the competition. Samsung's VNAND technology is the most advanced in the whole market.

Unlike all other companies endurance TBW values, Samsung's based vNAND SSDs tend to reach more than 3x the warranted TBW. For example the Samsung 960 PRO even reached more than 10 times of what it was originally warranted to reach. There are tests and videos about it.
I am certain that they managed to improve this with their newest standard even further, so they could reach such values fairly easy using TLC instead of MLC (with the 980 Pro). Let's say they only managed reach half of it given the use of TLC instead of MLC, the TBW of the 980 Pro 1TB model with 600TB would still mean that you can de facto write as much as more than 3PB without any issues.
You will never have this durability and endurance with any other brand other than Samsung. Not even Micron or WD was capable of reaching this much with their products in the tests I have seen.

Which is why, at least for my personal opinion, Samsung quite leads a monopoly with their storage cell and controller technology at this point. People just don't talk much about it.
In our company we only use Samsung SSDs, we never recommend anything else as long as there is a fair amount of budget available that is.

Here are some sources for you, unfortunately they're not in English language though:

https://www.heise.de/select/ct/2017/1/1483369302343280
Heise-Online from Germany tested the competition, they're a very reputable and relatable IT magazine in Germany. In this test even the Samsung EVOs were - by far - better than any of the competition.


Those Guys from YouTube also tested a Samsung 860 Pro, they managed to overwrite 7 PB of data into the SSD over a long term test, while their system also crashed several times due to power shortages etc. the SSD still shows a 100% good standing with Crystadisk Info and it operates normally without issues whatsoever.

Samsung's PRO series really are something else. As for Samsung, I think you can fairly ignore TBW values. Durability and endurance in terms of chip, controller and storage cell technology and quality they're using is far above that level.
