Toshiba has showed off a NAND flash device using through-silicon vias (TSVs) to stack 16 NAND dies, a technology it announced earlier this month. From Tom's Hardware:
TSV technology removed the wire bonding from the edges of the die. Instead, the signal is passed through the entire stack vertically. Vertical NAND, often referred to as V-NAND or 3D NAND, differs from TSV, though. Nothing leads us to believe that the two technologies can't work together, but at this time we are unaware of any designs that merge the two technologies.
[...] Toshiba's partners are excited about this product for two reasons: The first is performance. PMC Sierra makes very high-performing NVMe SSDs that move the bottleneck from the PCIe interface to the flash itself. The Princeton controller uses 32 channels to address a large number of flash die and is a very expensive controller to manufacture. If the company is able to reach the same performance level with just 16 channels, the overall cost will drop. The capacity can remain the same because TSV allows Toshiba to stack twice the number of die in each package.
Performance is only one aspect of the overall datacenter equation, though. The upfront costs are minimal compared to the long term costs due to power consumption. PMC Sierra demonstrated a very wide gap in power efficiency between non-TSV Toggle mode flash and new TSV Toggle mode flash.
The use of TSV could help scale NAND capacity in the vertical dimension even further.

I've got another story about NAND coming for you later.
Here is a sneak preview:

This is one area where I have to call BS, as the size of data from camera and video just keeps growing and growing at a pace that the SSDs just don't match, at least not at a price point Joe Average will pay. The way my customers have been going is the way I think computers will be going, with an SSD and a HDD on the desktop and an SSD with an external HDD on the laptop. This way they get the bulk storage all those pics and vids and shows and tunes require without having to spend insane-o money on a Tb SSD. Also never forget that RAM trumps all, no SSD comes close to the speed of RAM and with the price dropping like crazy on RAM its quite easy to build a system where the OS doesn't touch the drives once its booted.
Will there be people that go all SSD? Sure such as those that don't give a single fuck about privacy, they'll probably just use the Win 10 OneDrive to store all their docs and pics and call it a day, but I have a feeling most folks will end up with both, as HDDs give you the space while SSDs give you the speed. Maybe Toshiba or Seagate will do what I thought should have been obvious 2 years ago, build a hybrid with 128GB-256Gb of SSD with a 3TB HDD so the OS and programs can be SSD while the data can be HDD but until that happens I'll keep advising my customers that having both is the best course.
ACs are never seen so don't bother. Always ready to show SJWs for the racists they are.
