Micron and Intel Announce 3D NAND Flash Co-Development To Push SSDs Past 10TB
MojoKid writes Both Micron and Intel noted in a release today that traditional planar NAND flash memory is reaching a dead-end, and as such, have been working together on 3D memory technology that could open the floodgates for high densities and faster speeds. Not all 3D memory is alike, however. This joint development effort resulted in a "floating gate cell" being used, something not uncommon for standard flash, but a first for 3D. Ultimately, this 3D NAND is composed of flash cells stacked 32 high, resulting in 256Gb MLC and 384Gb TLC die that fit inside of a standard package. That gives us 48GB per die, and up to 750GB in a single package. Other benefits include faster performance, reduced cost, and technologies that help extend the life of the memory.
Hopefully this also sees a reduction in the cost of SSDs to bring them closer in line with platter drives, which have only just started dropping into the $30/TB range once more (since the Thai floods gave manufacturers their own Sumitomo excuse to drive up prices).
If the market had progressed more realistically, platter drives would be $15/TB and we'd already have consumer-level 10TB drives, but Seagate and Western Digital took a breathing period to reap profits, allowing SSD technology to start playing catch-up. ...not that SSD makers are off the hook... they've gone to smaller fab processes that shortened the life of NANDs and also have kept prices from falling at a reasonable rate, too.
I think we are two or three breakthroughs from reaching parity on cost per byte for platter and solid state tech, at which point, platter technology will likely become a very small niche market.
750GB per package.
A single SSD may have anywhere from 1 to $alot of packages on the board, hence 10TB SSDs.
More data, damnit!
At this rate I'll finally be able to have my entire music collection on an iPod without having to compress my music in that terrible FLAC format. FLAC is a "lossless" format but you can totally hear which bits have been squished into the file for too long! That's why I decompressed all my files and let them sit for a week, so that the bits can breathe.
Anons need not reply. Questions end with a question mark.
750GB is the amount they can fit one one chip package - i.e. what they could fit on a SD card. A typical gum stick SSD has several of these (usually around 5), hence the 3-4TB per gumstick estimate. A 2.5" drive will typically have more like 12-15 of them, hence the 10TB estimate.
I have upgraded 4 computers from HDD to SSD's since Christmas. They were all from 2 to 5 years old, and all of them run like they're a brand new computer. They boot amazingly fast, and they launch programs really fast. Compiling is much, much better too. I wouldn't ever go back to a rotating hard drive for anything other than long term archival storage now. Maybe I'd do a hybrid drive, but really around $100 or so for 240GB is a really nice sweet spot at the moment.
