It’s that if you had a running program that wrote tiny fragments to the same cells, you could burn the cells out faster – one of the components of ssd’s that has to function is to move data from being written to the same cells over, hence the even balancing of writes to all unis of a ssd while moving stored data around on units that hold the stored data to prevent cells from being unable to store data due to the cells getting “stuck” at the voltage that contains the bits after having the same value for too long. NAND1 is pretty much the most reliable but also the most expensive due to how much you need to have a large amount of storage as each cell only stores 1 bit; problem with more dense storage is that it absolutely needs to have the data shuffled around to prevent cells from kicking the bucket.
 
TLDR;;  
Dumb programs writing to the same cells can burn them out, dumb controllers that don’t know how to move data to even out the writes have the same issues which also are OS’s that have to have the drive map in memory if the SSD’s do not have a DRAM cache for the drive itself on the controller.  
Mostly a non issue from what I can tell, most drives are cheap enough to manufacture with NAND 3D and up are cheap enough to include DRAM cache and controller

Maybe, I mean superfetch is still better than SSD’s as “ramdisks”/ RAM is basically the fastest ram storage you get. I’ve seen 2018 articles about how to turn superfetch off, but frankly the amount of swap and iops that go on with win10, I would just say leave it on – any caching it can do the better. Though I’ve no idea if they did disable it for SSD’s now since they can detect that, but I don’t read release notes because whatever, it is what you get force fed by windows updates. Though you can kill it through the services manager in %windir%\system32\services.msc if it’s being an issue

@Ebalosus  
Pretty sure superfetch is now disabled for ssds lol  
And doesn’t superfetch just save something in ram?
 
@TartarusFire  
All I know is even on my drive which is like 7 years old, it only has like 30tb NAND writes  
Some people freak out about the silliest stuff like torrent for example is pretty much all reads.. extremely few writes  
But people assume when you’re using it that it’s writing a bunch - why?  
Idk there’s just silly stuff

@TartarusFire
 
Ah, so you still have to manually turn off superfetch and prefetch for Win10 SSD installs?

@ABronyAccount  
Only if the storage has a controller that has load balancing; main issue is if the drive does not have a controller or the OS is just a direct map, or the drive controller has a very bad load balancing for writes, what can happen is that the same region of flash memory is written to constantly and causes the region of memory cells to die. This is a very possible outcome with swap heavy and I/OP heavy programs such as media editing programs and OS’s – especially a stock Windows10 experience.

For typical household consumers, even for SOHO users, the guaranteed lifetime of good T/QLC is plenty.  
Plus, I’ve read that even very dense QLC flash is better for cold storage than mechanical HDDs due to the lack of moving parts that could seize up over time, and without being a write-centric workload it’s not being pushed to the breaking point.

@Cyan Lightning
 
I agree, but personally for drive lifetime and reliability I go with SLC or MLC for certain setups in my own builds; but since clients are more price-conscious, I get them TLC or QLC drives from reliable vendors like Crucial.

And here I am thinking, do we really need 300,000 write cycle? I mean don’t me wrong. It’s awesome, but at the same time doesn’t that sound way overkill? If you are building a server and maybe if you’re an enthusiast then well that’s for you. But for average consumer? I don’t think so. And not to mention SLC and MLC hell a lot of expensive than TLC and QLC which again for average user with average salary will think twice before buy it.
 
It’s like buying a computer with dual sli GTX 1080 TI and Intel i9 extreme edition for someone that all they do is just watching a cat videos

@Prometheus labs CEO
 
Technically yes, but “MLC” usually refers to dual-layer storage.

@Ebalosus  
but aren’t TLC and QLC different types of MLC, unless you mean 2-level cell

@Prometheus labs CEO
 
SLC and MLC have much longer read/write lifetimes than TLC and QLC.

@Ebalosus  
Which one is which?

@Rainboom Dash
 
In theory yes, but it tends to depend on whether programs are secured against write-propagation, and what people are doing. It’s why I’m glad that Apple’s obnoxious soldered-in storage is at least SLC or MLC, so they’ll last a long time.

I mean there’s nothing wrong with QLC for the average person  
I got a 1tb ~1500mb/s read and write speed drive for 100 bucks.. now I understand that if you do a lot of copying of files to it that it’ll slow down greatly before it finishes… but I don’t do that so no issue there and even if I did I’m in no rush  
And of course endurance isn’t great but it’s rated at 200 TBW and if I get even half that then I’d say PLENTY
 
Sure, they aren’t for everyone but they are awesome for the average person

@Prometheus labs CEO
 
>300,000 lifetime writes vs. 50,000 lifetime writes

 
Vs  

Why is this so accurate

@[….][xx…][x…]
 
In my experience they’re pretty easy to find…just not necessarily at economical prices.

SLC is the best, I value lifetime and speed over capacity. Wish SLC flash drives were easy to find :/

SLC/MLC > TLC/QLC

That just raises further questions!

Just to put things in perspective, Samsung was manufacturing 96-layer V-NAND this past summer, and is now producing 1-TB chips in eUFS packages (11.5mm x 13.0mm). Sometimes, living in the future is awesome, especially when you were there to witness the technological limits of yesterday.

LoL I can see the tagline now:  

 
Side note: A chinese company called HiSilicon designs a line of ARM-based SoCs called “Kirin”.

RaiNAND - 20% more durable and faster than NAND

3d nand is basically just stacking chips on top of each other. Very simple concept but the logistics is the true challenge!p

I mean technically the left is 1D NAND and the right 2D

Thanks to Starbound I almost have some idea what’s going on here.
