Micron Reveals 232-layer NAND Flash During Investors Day
During its investors day yesterday, Micron revealed its 232-layer NAND Flash, which for now is the most advanced of its kind. Micron is using what the company calls CMOS Under Array or CuA as the platform to build a pair of TLC stacks on top of, for a total of 232-layers. Each stacked NAND Flash chip is said to have a capacity of 1 Terabit, or 128 GB, so we're not seeing any new capacity increases at this point, compared to the competition, but Micron is promising increased bandwidth node-over-node, so we might end up seeing better performance compared to its competitors. The new NAND Flash is supposed to be optimised for SSDs and other "managed" NAND, such as eMMC and UFS.
Micron also revealed an updated NAND Flash roadmap, with the company planning even more 200 plus layer products before moving to 300 and 400-layer stacks of NAND in the future. The 300-layer stacks are already under structural development, whereas the 400-layer products are still in the very early stages of research. The new 232-layer products are said to go into mass production towards the end of this year, so we shouldn't expect to see products based on Micron's 232-layer NAND until sometime in 2023.

The way things are developing, the products are getting worse, not better.
It's just taller stacks of the same kind of NAND.
Please share if you have some insight into how this makes for poorer lifespan.
Am I the only one who wants to see a viable SSD in price and performance with an SLC level lifespan?
From the point of view of the manufacturer, SSD's sell like hot cakes at current prices, they have a clear advantage over spindles, so there is no market need to lower the cost per gigabyte faster.
They can also make higher capacity SSD's than they do now but I think they are waiting for a bigger market to justify it and to try and keep enterprise user's from using consumer products.
I am associating more layers with higher lifetimes, I hope thats what the increase in layers develop into.
While games are 3-4x larger than in the past this price reduction is offset by the fact that you need to buy 3-4x larger capacity storage to meet your needs.
Yes, I'm sorry but I hope someone makes better products, not the same or worse.
SLC hasn't been a thing in the consumer space for over a decade.
How are SSDs less secure than HDDs? Please provide an example, otherwise it's just your opinion.
SLC or TLC isn't going to help with keeping your data secure, either can fail just as easily.
No storage medium is secure, as such a thing hasn't been invented yet, but there are apparently companies working on allow for data storage in diamond wafers, but I guess you'll complain the price per exabyte will be too high.
Maybe you should go complain to the game developers then? As your issue is clearly not with the storage device makers, or are you suggesting they're colluding and refusing to release cheaper/larger storage devices for you to store your games on?
I guess you don't remember that MLC SSDs topped out at 1 TB and would set you back a small fortune. The 512 GB version of the Samsung 970 Pro was US$229, you get a 1 TB PCIe 4.0 drive for that kind of money today and you can get a 2 TB PCIe 3.0 drive for that kind of money, but no, it's still too expensive for some.
Here's a suggestion, if you're not happy with what's out there, how about you put in some money, start your own company and invent something faster, cheaper, better?
The size of games is a side effect of advancing quality and it will get worse, it also demands bigger and faster storage, so there are two problems. When a problem is created, someone is expected to create a solution to the problem.
In the meantime, unfortunately some consumers are happy to defend the stagnation of technology, I hope they're at least getting paid for it. And no, no one here is going to create a company from scratch whenever there is stagnation or problems in some industry. This is ridiculous, even if it's just a joke.
You might also want to have words with someone like Elon Musk, he didn't start an electric car company, nor a space business due to stagnation problems...
For someone who claims to be so old, I was expecting a more mature point of view, I think soon you will be quite happy putting 1-2 games on 1TB SSD.
Tesla has absolutely nothing to do with the discussion. But I would easily bet against a company that offers absolutely nothing really innovative.
I'm a realist and we've gone from a time when it was reasonably affordable to come up with new, better, faster tech, to a point where even a small step costs insane amount of money to accomplish. If you're not willing to understand that part, there's nothing I can do to help.
Oh and I just spotted a 2 TB NVMe drive for about $134 here, not a great drive, but even so. But no, SSDs are not getting more affordable...
If you want SLC, you need to be ready to pay (at least) 3x as much per capacity, simply because capacity per die will be exactly ⅓rd and no more. That's the only difference between SLC and TLC after all. It is a logical and physical impossibility for SLC or MLC to match TLC on price, everything else being equal.
As for complaining that SSDs are more expensive per capacity than HDDs: one has been on the market a rough decade, the other more like five (though admittedly in very limited use early on). What do you expect in terms of economies of scale and optimization? HDDs are also fundamentally much cheaper to produce per capacity (but not in base cost due to material/component needs - motors are expensive, for example). Also, SSDs deliver many times the performance. Isn't that worth paying for?
My first SSD was an 80GB Intel drive in... 2008? And even that was MLC, not SLC. SLC drives have never been viable for consumer sales due to the cost.
And, crucially, current TLC drives are very reliable, and do not wear out quickly. Yeah, doesn't 3D TLC use significantly larger cells than planar, as they no longer need to pack them as densely as possible?
It would be nice to have the option to get a 64GB (or larger) SLC drive for a scratch drive or something that's going to take a ton of abusive writes and still stand up.

What would be cool would be if drive vendors allowed for more flexibility in configuring their drives for the end user. For example, they could allow for alternative firmwares applied through their own drive management software that force the entire drive to run only in pseudo-SLC mode, at the cost of 2/3rds of its capacity - turning your 1000GB drive into a 333GB one, etc. This is likely a non-trivial undertaking though, given that the controller firmware would need significant changes and the increased performance would put more stress on the controller, increasing heat output under sustained loads. But it would be an option, much cheaper than bespoke products, and it would be pretty neat even if extremely few people would end up using it. (And of course there's increased risk involved as such a firmware change would require reformatting the drive, increasing the likelihood of PEBKAC errors.)
