Samsung releases their all-new 860 QVO series SATA 6 Gb/s SSDs. As the Q in the name indicates, this is all new QLC based NAND. Don't worry, we'll explain it all but the bottom line is that you will see a new value product series that offer more bang for your bucks and an increase in volume sizes.

As I write in the article, I do not foresee any issues with reliability based on normal PC usage workloads. Samsungs problem is trust, they should have gone for 5-years warranty (and lower prices). We've seen exactly the same happen with TLC when it was released and at this stage, TLC has become a commonly accepted type of NAND.
Bigger is better though for TBW values, with 100 GB per day writes (!) the SSD would last almost 20 years before the last cells are depleted. 2TB SSD is rated at 720 TB
720TB writes / (100GB/day x365) = 19.73 Years.
Also if I may throw in an argument, there are plenty of tests on the web where say SSDs rated at 200TB lasted over a petabyte ... then again, 4 bits per cell is new technology, we do not know how it'll behave long term.

Interesting, my old rusty samsung 830 ssd, is almost 7 years alive and kicking. And it was also a 3-year warranty given disk.
I believe playing some games during the day aren't so tiring for the disk after all. Only when installing and patching you could slightly reduce faster that lifespan in the end. Thanks. I'll keep an eye on the news if something happens after some usage worldwide.

it's non-volatile memory. it will last longer than a hdd
And how long will data last without power?

Non-volatile memory easily leaks without sustained power through the time. A month would be enough to get few bad blocks (leaked cells) with non-fresh MLC.

Really don't trust this QLC memory enough for my data. Wouldn't wanna fill this up either (as you never should with SSD's)
Better off buying a 2 to 4 TB HDD for your storage needs where you can actually use the entire drive. Stick to pro's and maybe EVO's for the important stuff.
Not with QLC drives, i wouldn't.
