64-layer Vertically Stacked NAND? That's old news, 128 layers coming.

64-layer Vertically Stacked NAND? That's old news, 128 layers coming.

The developments in the NAND FLASH segment (the storage chips in your SSD) over the years have astonished and astounded many. The effort to get more cells into one package to achieve bigger and cheaper production soon will reach new heights. 

Toshiba and its strategic partner Western Digital are nearly done with the latest iteration: 128-layer 3d NAND. A year ago we were at 48 and 64 layers NAND. This year 96-layers is the development and yeah the industry never stops as 128-layers are coming to town. Basically with 128-layer NAND you can double up that (example) single 32 GB NAND IC towards 64 GB in the same yet slightly thicker package size.

Toshiba in cooperation with Western Digital (and we assume Sandisk) now are actively developing BiCS-5 NAND. A 128-layer die will be BiCS-5 in Toshiba flash generation naming terminology – BiCS-4 is 96-layer and BiCS-3 is 64-layer. The first NAND packages are to be offered as a 512 Gbit package (512/8 =64GB) based on 3-bits per cell (TLC). 

Toshiba can achieve this by adding third more layers over the 96-layer version. That results in 128-layers. It is expected that BiCS-5 NAND will reach volume production next year with high volume the following year.

Waiting on 1024 layer NAND and maybe we'll have HDD prices... :P

That hint of sarcasm. lol
Seriously, though, you can get good 1 TB NVMe SSDs these days for around $145, and a decent 1 TB SATA SSD for $90. I can see it happening in the next couple of years. :)

HDDs of course also get cheaper and bigger. But its really not unthinkable anylonger to have a pure SSD system. I know, because thats what I'm running right now. Granted the 4TB SSD wasn't cheap, but so worth it to not have anything load from a slow HDD anylonger.
I don't store videos or anything on this machine though, I have a NAS for any media-related storage, so its litereally just apps/games, and work data.

Storage is so underrated. People don't realize how bottlenecking a HD is.

When people realise the potential, they'll never go back to old HDD.
I made the push to buy a 256Gb SSD when they costed 115€. Don't regret it one bit, as I've saved hours on loading times over the years.
I'll be upgrading my tower soon, and will be looking for a medium to high performance NVMe to upgrade system responsiveness again.
As I see it SSD SATA drives are getting cheap and good for storage, but you can't beat that premium speed from a NVMe with OS and your favourite apps.
