The 218-layer 3D flash memory leverages 1 Tb triple-level-cell (TLC) and quad-level-cell (QLC) with four planes and features innovative lateral shrink technology to increase bit density by over 50 per... Kioxia and Western Digital Announce 218-layer 3D Flash NAND Memory
Any guesses on when SSDs will match HDDs in price/capacity ? All these tech progresses, and yet they are still behind by several orders of magnitude.
If HDDs keep progressing as they have, maybe 10 or 20 years: who knows? 10 years ago SSDs were too small and too expensive, but today you can easily buy one you could use daily. For storage purposes HDD do perfectly fine, price and security they're the wisest choice: a failed SSD is 99% probability of data loss, wile you can always try to get your data back from an HDD.
Yeah, and don't forget that if paying attention, you can usually notice a HDD is "tired" and can move data away from it before it goes poof. With a SSD, it just happens completely out of the blue with no warning whatsoever. But I do love the speed of SSDs, and with my new 2.5gbps internet (possibly 10gbit in a year or two), HDDs are becoming the bottleneck. I really hope prices of SSDs drop enough so they are viable for large volume "active" storage.
About a decade considering last decade we went from 100 euros for 120gb to 80-100 euros for 1 tb, so we got 8x density, I do not think we will get another 8x but I can see in 2030 4tb ssds for 80 euros ! I hope I am waaaay off on my predictions and we get there sooner!
How scalable is this multi layer thing? There will be one thousand or one million multi layer 3D NAND?
I will not be surprised to see 500 at some point, although I have 0 knowledge on the matter so I am talking out of my butt .... But even if the chips literally double in height .... I see no issue with it.
the answer is probably never for larger capacities, magnetic storage is cheap, I suspect that newer technologies will replace nandflash before it gets there.
Density wise SSDs have already overtaken HDDs as far as I can see based on current price listings. Highest capacity SSD listed has 30TB for €3160 15TB for €1160 HDD 22TB €435 18TB €280 If HDD can't keep up with capacity of SSD at some point the €/TB advantage should likely follow.
its pretty hard to beat the wizardry of storing bits on magnetized steel discs or tape. right now we're kind of at a weird spot, you can certainly make much bigger singular drives with nandflash, but the cost isn't looking like its going to go down alot without a pretty severe performance hit, with more bits per cell, those qlc chips are pretty garbage, more layers hits diminishing returns aswell. The only way I can see 2-3x the density for the same price at a acceptable performance level, if if there is some major innovation. which doesn't appear to on the horizon for nandflash anyway. its also worth mentioning , that pretty much nothing can beat tape, you can get 18tb lto tapes little bit larger than a 90mm fan, and they probably cost <$30 to make. https://tapeandmedia.com/fuji-lto-8-tape-ultrium-tapes-16551221.asp , 12tb on sale for $54, if only it wasn't sequential media.
probably because they are used for archival storage for companies. volume is going to be pretty low edit: also longevity, probably have to last at least 15 years probably more like 20-30 years
