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!
All others are perpetually above $100 which is too expensive for a Facebook wonder do-nothing PC with a pentium 4th edition and 4GB of RAM.
Why use an SSD in such a do-nothing PC? If you can't go with a regular HD try a hybrid SSD-HD. Last I looked a hybrid with 1 TB HD and 8 GB SSD was under $80.
You have a faulty SSD if you've got to 12% worn in 1 month. For a non-faulty 840 EVO 1TB that's a physical impossibility. 12% wear would imply that you've written more than 36TB to the drive already, which implies writing continuously at 833MB/s, which is higher than the drive's maximum write speed.
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.
Centralized remote syslog server that also feeds to Elasticsearch which indexes the syslog entries for reporting and searching. After daily aggregate reports are done, a week later the entries are moved to spinning rust and only the canned reports stay on SSD. With the way Lucene works and our indexing is setup, a 100 byte syslog entry can easily turn into 2k of index. The canned reports now only take a tenth of the time they took before we added the five Samsung drives and the historical reports load even faster than that, but the drives are just wearing out too quickly for comfort.
So you're simply using the wrong drives. The 840 EVO is a consumer level drive. You want a more enterprise like drive like Intel 3700, which is warranted for 10 drive writes per day for 5 years. It costs more, sure, but you can surely justify the cost based on the performance and reliability benefits.
You're doing it wrong! Unless you don't care about data loss and calculated out that replacing the EVO's every few months is actually a cheaper option compared to a decent SLC (Intel, STEC, ...) or even RAM SSD over the lifetime of your server, then I would recommend re-examining your setup. SLC's are not only faster, but they're a heck more reliable. If you just care about speed on a single box, get a PCIe based SSD. Desktop drives for this kind of setup is asking for trouble.
I still have a set of 32GB SLC (Intel X-25-E) from 2009 which have digested several PB worth of data in their lifetime as well as a number of OCZ Deneva's with the same workload. Probably the best investment possible.

I built a FreeBSD 10.1 server with a single root ZFS pool consisting of seven 3 TB drives in RAID-Z3, including a small 7-way mirror of swap space. The process was completely pushbutton using the install UI. Partly I did it just to explore how much difficulty the install might be (no difficulty whatsoever), but the setup has proved very effective in use.
It was pretty cool rerouting some of the SATA connections randomly (even to a different HBA) as a test, and removing two of the drives as a test, and having it still boot to a fully operating state and run fully usably with no intervention or drama at all.
After extensive experimentation and production use, the only real criticism I have that is just head-scratchingly stupid and lame is that there is no sensor capability, and no one in development seems to think there is a glaring problem with its omission. Coretemp works beautifully, but you can't detect fan rotation or access any voltage or secondary temperature sensors.
Get more RAM and disable the page file. I did that years ago, and it works just fine. I've had *one* OOM blue screen in 4 years, and that was because I was seeing how much I could open at the same time.

Yeah spell it right - it's 'systemd'. Looks like an OK operating system, shame it doesn't have a decent init.
