Here are some goodies from yesterdays briefings at the 2014 Samsung SSD Summit:
Slides from the 3D V-NAND discussion. These provide some additional visuals for what I explained in the intro to the 850 PRO series SSD review:
Next we got into current launching lineups. First the 850 PRO that launched today:
Samsung also launched an 845DC PRO, which uses the previous generation 24-layer V-NAND:
Finally, as we walked out of the conference, we saw a 32-layer V-NAND wafer on display:
Taking die pictures is tricky...
...but persistence is rewarded:
More to follow!
Samsung has certainly been pushing the envelope in the SSD field. For the past two years straight, they have launched class leading storage products, frequently showing outside-the-box thinking. Their 840 PRO series was an impressive MLC performer to say the least, but even more impressive was the 840 EVO, which combined cost-efficient TLC flash with a super-fast SLC cache. The generous SLC area, present on each die and distributed amongst all flash chips within the drive, enabled the EVO to maintain PRO-level performance for the majority of typical consumer (and even power user) usage scenarios. The main win for the EVO was the fact that it could be produced at a much lower cost, and since its release, we've seen the EVO spearheading the push to lower cost SSDs.
All of these innovations might make you wonder what could possibly be next. Today I have that answer:
If you're going "Hey, they just changed the label from 840 to 850!", well, think again. This SSD might have the same MEX controller as its predecessor, but Samsung has done some significant overhauling of the flash memory itself. Allow me to demonstrate.
Here's standard (2D) flash memory, where the charge is stored on a horizontal plane:
..and now for 3D:
The charges (bits) are not stored at the top layer. They are stored within all of those smaller, thinner layers below it. You're still looking at a 2D plane (your display), so here's a better view:
Seeking asylum at some random baggage claim area?
Guess again. Here's a hint:
More to follow, boys and girls. Stay tuned!

If the information provided to DigiTimes is correct we may be in for a price war between SSD manufacturers. We have seen price drops in flash memory, especially with the advent of TLC and asynchronous flash which have been heartily approved by most enthusiasts. However there is a chance that in the coming months competition will start driving prices of SSDs down but may have the opposite impact on other products. Micron is planning on reducing the amount of memory it sells to other companies in order to ramp up its stock of SSDs and SanDisk has jumped into the market with both feet. You can also expect to see all the major manufacturers start putting out more M.2 drives as adoption of Intel's Z97 board grows.
"The SSD industry is heading for fierce price competition as major suppliers, including Micron Technology, Intel, Kingston Technology, SanDisk and Samsung Electronics, are gearing up efforts to outperform others, according to industry sources."

A couple of really nice Amazon picks hit my email box today and I thought they were worth posting for our readers as well.
First, and clearly the most exciting: the 1TB version of the Samsung 840 EVO SSD is now selling for just $399. That comes in at $0.399/GB, which is actually better than the cost per GB of the Crucial MX100 that launched this month. If you haven't picked up an SSD that is big enough to hold all your games, this is the perfect opportunity!
Also, after our review went up at the end of May, the 4K ASUS PB287Q 28-in monitor is finally up for sale on Amazon for $649 with a shipping date of July 1st. If you think you might be interested in the universe of gaming at 4K, now is a great time to jump in.
Thanks for supporting PC Perspective!

In The Tech Report's ongoing SSD endurance challenge, three SSDs are soldiering forward. We have reached the thousand-terabyte mark, which is at least five times more than any of the survivors are rated for. These survivors: The Corsair Neutron GTX, the Samsung 840 Pro, and the Kingston HyperX 3K. Technically, the HyperX was able to reach 1PB of written data with performing only 716TB of actual writes, due to compression.
Image Credit: The Tech Report
Of course, each of the drives are less-than prestine. The Corsair Neutron GTX 240GB was slowly decreasing in its "life" attribute since the beginning, claiming to be somewhere between 75% and 80% with a fairly linear decline. If this trend continues, the drive will reach "zero" at around 4-5PB of writes. That said, its read speed has substantially dropped from the time between 900TB and 1000TB of total writes, from 500MB/s to just under 400MB/s. Also, this "life" could drop substantially if the drive encounters reallocated sectors (which this model has apparently yet to do).
The other two drives are a similar, remarkably successful story.
The Kingston HyperX drive is reporting itself to be substantially worse off, within the last 10% of its life. That said, even though it claims to be pining for the fjords, it is still working and has only reported a couple of reallocated sectors, those occurring in the last 100TB of writes.
The Samsung 840 Pro seems to still be going strong, although it had more zero or "a couple" of reallocated sectors -- every hundred terabytes yields about 500 reallocations.
As always, this is just our brief discussion of what The Tech Report found out. Be sure to check out their full article for many more benchmarks, tests, and conclusions.

Well that was an alphabet soup of a title.
Samsung has just announced a new line of SSDs, based on three bit per cell (TLC) memory, for enterprise customers. The Samsung 845DC EVO is rated at 530MB/s reads with 87,000 IOPS. The company will also cover up to 600TB of writes under its warranty (no mention of length in years, though). The drive will be available "later this month" in 240GB, 480GB, and 960GB models. Samsung did not mention price in their press release, but Anandtech claims the 240GB will be $250, the 480GB will be $490, and the 960GB will be $969.
Samsung's SSDs will give you some TLC???
This is basically $1/GB scaling, plus $10. I must admit, this is getting pricy. In the consumer space, we have recently seen 512GB for $199. That said, SSDs are not known for sticking to their MSRP. Also, these are enterprise-rated drives. Being TLC-based, I wonder how much (if any) SLC-style write cache was included, as per the consumer 840 EVO.
Lastly, Samsung claims that these drives use around 4W under load. This is much lower than hard drives but a little high for SSDs, according to benchmarks that I have seen. That said, there are a few ways to parse that (for example, if they mean that its peak is typically 4W, which would be pretty good for a 960GB drive).
The Samsung 845DC EVO will be available later this month for a little over $1/GB.

Hardware/Software Picks of the Week:
3840x2160 for Cheap!!
It has been just over a year ago when we first got our hands on a 4K display. At the time, we were using a 50-in Seiki 3840x2160 HDTV that ran at a 30 Hz refresh rate and was disappointing in terms of its gaming experience, but impressive in image quality and price ($1500 at the time). Of course, we had to benchmark graphics cards at 4K resolutions and the results proved what we expected - you are going to need some impressive hardware to run at 4K with acceptable frame rates.
Since that story was published, we saw progress in the world of 4K displays with the ASUS PQ321Q, a 4K monitor (not a TV) that was built to handle 60 Hz refresh rates. The problem, of course, was the requirement for a multi-stream connection that essentially pushes two distinct streams over a single DisplayPort cable to the monitor, each at 1920x2160. While in theory that wasn't a problem, we saw a lot configuration and installation headaches as we worked through the growing pains of drivers and firmware. Also, it was priced at $3200 when we first reviewed it, though that number has fallen to $2400 recently.
Today we are looking at the Samsung U28D590D, the first 4K panel we have seen that supports a 60 Hz refresh rate with a single stream (single tile) implementation. That means that not only do you get the better experiences associated with a 60 Hz refresh rate over a 30 Hz, you also gain a much more simple and compatible installation and setup. No tricky driver issues to be found here! If you have a DisplayPort 1.2-capable graphics card, it's just plug and play.
The Samsung U28D590D uses a 28-in TN panel, which is obviously of a lower quality in terms of colors and viewing angles than the IGZO screen used on the ASUS PQ321Q, but it's not as bad as you might expect based on previous TN panel implementations. We'll talk a bit more about that below. The best part of course is the price - you can find the Samsung 4K panel for as low as $690!

Samsung has been working with TLC flash for a while now, both the original 840 and the 840 EVO utilize that type of flash, the increased yields offer lower pricing at the cost of a reduced number of writes before the flash begins to fail. The Register has posted their announcement of a new product line aimed at the data centre; the PM835T family will come in 240GB, 480GB and 960GB models and will also use TLC flash, with pricing predicted to be comparable to consumer level drives. With Samsung's 10nm-class TLC flash the experts at SMART suspect a 500 phase/erase cycle lifetime however depending on how Samsung has designed the drives the actual number could be much higher, they do offer a 3 year warranty on their current TLC drives. For now Samsung is not releasing an official expected lifetime for these drives which raises a question, will enterprise feel the short term cost savings are worth the long term replacement costs?
"Triple-level cell (TLC) flash chips mean fabs can extract more flash capacity from a silicon wafer, and so production costs are lower than for two-level cell MLC technology. Samsung says it gets "a 30 per cent increase in manufacturing efficiency compared to SSDs that use 2-bit NAND flash components."
