Fasetto is a company previously known as one of those cross-platform file-sharing web apps, but I was shocked to see them with a space at CES Unveiled. Companies without physical products tend to fall flat at this type of venue, but as I walked past, boy was I mistaken!
To give the size a bit of perspective here, that's a business card sitting in front of the 'Link', which only measures 1.9x1.9x0.9" and weighs just under 4 ounces. That's a belt clip to the right of it. Ok, now that we have the tiny size and low weight described, what has Fasetto packed into that space?
- Aluminum + ABS construction
- Waterproof to 45 feet (and it floats!)
- Bluetooth 4.0 LE
- 802.11AC dual band WiFi (reportedly 4x4)
- 4GB RAM
- Quad core ARM CPU
- 9-axis compass/accelerometer/gyro
- 1350 mAh Li battery
- Wireless charging (Chi style)
- Up to 2TB SSD
For a portable storage device, that is just an absolutely outstanding spec sheet! The Link is going to run an OS designed specifically for this device, and will have plugin support (simple add-on apps that can access the accelerometer and log movement, for example).
The BIG deal with this device is of course the ability to act as a portable wireless storage device. In that respect it can handle 20 simultaneous devices, stream to seven simultaneously, and can also do the expected functions like wireless internet pass-through. Claimed standby power is two weeks and active streaming is rated at up to 8 hours. Even more interesting is that I was told the internal storage will be Samsung 48-layer VNAND borrowed from their T3 (which explains why the Fasetto Link will not be available until late 2016). This is sure to be a hit with photographers, as WiFi compatible cameras should be able to stream photos to the Link as the photos are being taken, eliminating the need to offload cameras at the end of a shoot.
We will definitely be working with Fasetto to help shake out any bugs prior to the release of this little gem. I suspect it might just be the most groundbreaking storage product that we see come out of this CES.

Introduction, Specifications and Packaging
This is it. This is the day we have been waiting for. Ever since we feasted our eyes on the NVMe version of the Samsung SM951, we’ve been begging Samsung to release this as a consumer product. Bonus points if it was powered by their 3D VNAND technology. It took them a while, but they came through, officially announcing the 950 PRO exactly one month ago, and launching them today! Not only will we dive into the performance of this new model, we will also include its results in our new Latency Distribution and Percentile testing.
Nothing has changed since the announcement. All specs remain the same very impressive 2.2-2.5 GB/s reads, 0.9-1.5 GB/s writes, and upwards of 300k IOPS, all from an M.2 2280 SSD consuming only 7 Watts!
While the 950 PROs will work with the built-in Microsoft NVMe driver (present in Windows 8 and up), Samsung has also provided their own driver, which will increase performance. The same was true for the Intel SSD 750 Series.
There’s really not much to this packaging, but it’s the most ‘retail’ we’ve seen for packaging of a simple M.2 SSD.

Tagged: vnand, V-NAND, Samsumg, 4TB, 48-layer, 2TB, 1TB
During yesterday's SSD Summit, obscured by their 950 PRO launch was new branding for their 32 (and now 48) layer Vertical NAND technology:
This new branding is more in line with what folks were calling their NAND anyway (Samsung was previously using the term '3D VNAND'. Dropping the 3D made sense, as it was implied with the 'V').
Also of interest were some announcements of upcoming higher capacities of their existing models:
4TB 850 EVO and PRO? Yes please.
1TB in the 850 EVO M.2 edition, and while there is no slide for this, the 950 PRO is also expected to be updated with a 1TB model within the same time frame as well.
How is all of this expansion possible? The answer is their third generation V-NAND, which is 48 layers and 256 GBit (32 GB) capacity per die. Samsung intends to roll this flash out and update all model lines currently using V-NAND technology. This decision was made by Samsung's Senior VP of Marketing, UnSoo Kim:
...now before you get out the pitchforks and form up the 'don't change the flash without a new model' lynch mob, I'd like to point out a few things that make this change different than what you might have seen in the past.
- Samsung is trying to prevent confusion by adding product lines with nearly identical specs.
- Samsung is being very open about this change (others were secretive / deceptive).
- Samsung has promised that they will only implement this change in a way that *increases* the performance and *decreases* the power consumption of these products.
I did leave the Q+A with some further questions about this change. The lower capacities of the 850 EVO still see slower write performance when writing straight to TLC flash (SLC cache is full). This is because there are fewer dies available to write the data, and each die can only write so fast in TLC mode. Since the 48-layer V-NAND is to have double the capacity per die, that would mean half the dies per SSD and possibly slower write speeds in the overall product.
I approached UnSoo Kim after the Q+A and asked this specific question, and his answer was both interesting and refreshing. First, he understood my question immediately and assured me that they will not roll out 256Gbit 48-layer V-NAND into their smaller capacity models - in order to prevent any performance reduction over their current 32-layer equipped parts. Second, he told me that they also intend to produce a 128Gbit variant of 48-layer V-NAND at some point in the future, and use *that* part to substitute the 128Gbit 32-layer V-NAND in those smaller capacity models, keeping the die counts (and therefore sequential write speeds) equal. That additional variant of their third generation V-NAND is the only way (in my mind) that they could update their smaller capacity parts without losing performance, and it was great to see that Samsung has thought out the execution of this rollout in such a proper manner.

Samsung’s new product launching will be called the 950 PRO. This will be an M.2 2280 form factor product running at PCIe 3.0 x4. Equipped with Samsung’s 32-layer V-NAND and using the NVMe protocol enabled by a new UBX controller, the 950 PRO will be capable of up to an impressive 300,000 random read IOPS. Random writes come in at 110,000 IOPS and sequential throughputs are expected to be 2.5 GB/sec reads and 1.5 GB/sec for writes. Available capacities will be 256GB and 512GB.
- 256GB - $199.99 ($0.78/GB)
- 512GB - $349.99 ($0.68/GB)
- 1TB - (early next year with the switch to 48-layer V-NAND)
The 950 PRO will be shipping with a 5-year warranty rated at 200 terabytes written for the 256GB model and 400 TBW for the 512GB. That works out to just over 100GB per day for both capacities.
These hit retail in October and we currently have samples in hand for testing.
(for those curious, both capacities only have components on the front side of the PCB)

Tagged: vnand, Summit, ssd, Seoul, Samsung, M.2, Korea, Global, 2015
As I hinted during last week's podcast, I am in Seoul, Korea to cover an upcoming press conference.
..and with a Samsung SSD Global Summit comes product announcements. Those don't happen until tomorrow (late tonight for you folks back in the states), but I did notice a clue on the cover of our itinerary folder:
See it? Here, let me help:
A VNAND powered M.2 (presumably NVMe) SSD is *exactly* the thing I have been waiting for Samsung to unleash into the wild ever since we reviewed their NVMe SM951. Given that Samsung's prior M.2 offerings gave the Intel SSD 750 a run for its money all while consuming half the power, and did so with Samsung's older 2D Planar NAND, you can bet a VNAND version will be something to behold. Let's hope this new model is released as a consumer product and doesn't end up as OEM-channel unobtanium like the NVMe SM951 was!
Keep an eye out for additional posts from our coverage of the 2015 Samsung SSD Global Summit!

Tagged: Samsung, vnand, 48-layer, tlc, 16TB, FMS 2015
I get these emails and comments all the time - "I want a larger capacity SSD". Ok, here ya go:
Samsung's earlier 48-layer VNAND announcement was exciting, but we already knew about it going into the keynote. What we did not know was that Samsung was going to blew the doors off of their keynote when they dropped this little gem. It's not just the largest capacity SSD, as this thing is more dense than any HDD's available today as well. That's 16TB of 48-layer TLC VNAND packed into a 2.5" form factor SAS-connected SSD.
...now what do you do once you have such a high density device? Well, you figure out how many you can cram into a 2U chassis of course!
Yup, that's 48 of those new SSDs, making for a capacity of 768TB in a 2U chassis. Samsung described this as a "JBOF" (Just a Bunch Of Flash), so processing the 2 million IOPS this array is capable of will have to be left to the connected system.
No word on pricing, but I'd think we are in 'mortgage the house' territory if you want to put this into your home PC.
There is more to follow from Flash Memory Summit, but for now I've got to run to another meeting!
FMS 2015: *UPDATED* Samsung Adds Layers to its 3D VNAND, Doubling Capacity While Reducing Power Consumption

FMS 2015: Samsung Adds Layers to its 3D VNAND, Doubling Capacity While Reducing Power Consumption
Samsung recently added 2TB capacity parts to their 850 EVO SATA SSDs, but today’s announcement may double that. Today at Flash Memory Summit, Samsung has announced a new iteration on their 3D VNAND technology.
Cross section of Samsung 32-layer VNAND. (TechInsights)
The announcement is a new TLC 3D VNAND (the type present in the 850 EVO Series). The new parts consist of an updated die with the following improvements:
- 48 layer VNAND - up from 32 layers of the previous generation
- 256Gbit (32GB) capacity - up from 128Gbit (16GB) capacity of 32-layer VNAND
- 30% reduction in power consumption over 32-layer VNAND
Samsung’s new 48-layer VNAND.
I suspected Samsung would go this route in order to compete with the recent announcements from Intel/Micron and SanDisk. Larger die capacities may not be the best thing for keeping performance high in smaller capacity SSDs (a higher number of smaller capacity dies helps there), but it is definitely a good capability to have since higher capacity per die translates to more efficient flash die production.
The Samsung keynote is at noon today (Pacific), and I will update this piece with any photos relevant to the announcement after that keynote.
I just got out of the Samsung keynote. There were some additional slides with data relevant to this post:
This image simply shows the additional vertical stacking, but adds that Samsung has this new flash in production right now.
The new higher capacity dies enable 1.4x greater density per wafer (realize that this does not mean more dies per wafer, as the image incorrectly suggests).
The power consumption improvements (right) were in the press release, however the speed improvements (left) were not. A 2x improvement in per-die speeds means that Samsung should not see a performance hit if they migrate their existing 128Gbit TLC VNAND SSDs over to these new 256Gbit parts. Speaking of which...
Not only is this new VNAND being produced *this month*, Samsung is retrofitting their 850 EVO line with the new parts. Again, we expect no performance delta but will likely retest these new versions just to double check for any outliers.
There was some more great info from the keynote, but that will appear in another post later today.

...you get the Samsung PM863 and SM863 lines of enterprise SSDs! These 2.5" SATA units were just announced, and as we suspected after reviewing the new 2TB 850 EVO and Pro, these new models can include even more flash packages, dramatically increasing the flash capacity. Here is a breakdown of the launch pricing and capacities:
SM863 (2-bit MLC VNAND):
- 120GB - $140 ($1.17/GB)
- 240GB - $180 ($0.75/GB)
- 480GB - $330 ($0.69/GB)
- 960GB -
$870 ($0.91/GB) < possible typo$640 ($0.67/GB)
- 1.92TB - $1260 ($0.66/GB)
PM863 (3-bit MLC VNAND):
- 120GB - $125 ($1.04/GB)
- 240GB - $160 ($0.67/GB)
- 480GB - $290 ($0.60/GB)
- 960GB - $550 ($0.57/GB)
- 1.92TB - $1100 ($0.57/GB)
- 3.84TB - $2200 ($0.57/GB)
These are some very competitive prices for enterprise SSDs, and the fact that the TLC version can cram just under 4TB into a 7mm 2.5" form factor is just astounding. The MLC version capacities appear to still follow that of the 850 Pro, minus a bit of available capacity due to higher levels of over-provisioning.
More impressive is the endurance ratings of these SSDs. The SM863 line is rated (varying by capacity) from 770 Terabytes Written (TBW) to an astonishing 12,320 TBW for the 1.92TB model! That's over 12 Petabytes! The PM863 is rated lower as it is TLC based, but is still no slouch as it ranges from 170 to 5,600 TBW for the 3.84TB capacity. The SM863 carries a 5-year warranty, while the PM863 drops that to 3-years.
We've been waiting to see Samsung's 32-layer VNAND appear in enterprise units for some time now, and look forward to testing them just as soon as we can get our hands on them!
Full press blast after the break.
Introduction, Specifications and Packaging
Where are all the 2TB SSDs? It's a question we've been hearing since they started to go mainstream seven years ago. While we have seen a few come along on the enterprise side as far back as 2011, those were prohibitively large, expensive, and out of reach of most consumers. Part of the problem initially was one of packaging. Flash dies simply were not of sufficient data capacity (and could not be stacked in sufficient quantities) as to reach 2TB in a consumer friendly form factor. We have been getting close lately, with many consumer focused 2.5" SATA products reaching 1TB, but things stagnated there for a bit. Samsung launched their 850 EVO and Pro in capacities up to 1TB, with plenty of additional space inside the 2.5" housing, so it stood to reason that the packaging limit was no longer an issue, so why did they keep waiting?
The first answer is one of market demand. When SSDs were pushing $1/GB, the thought of a 2TB SSD was great right up to the point where you did the math and realized it would cost more than a typical enthusiast-grade PC. That was just a tough pill to swallow, and market projections showed it would take more work to produce and market the additional SKU than it would make back in profits.
The second answer is one of horsepower. No, this isn't so much a car analogy as it is simple physics. 1TB SSDs had previously been pushing the limits of controller capabilities of flash and RAM addressing, as well as handling Flash Translation Layer lookups as well as garbage collection and other duties. This means that doubling a given model SSD capacity is not as simple as doubling the amount of flash attached to the controller - that controller must be able to effectively handle twice the load.
With all of that said, it looks like we can finally stop asking for those 2TB consumer SSDs, because Samsung has decided to be the first to push into this space:
Today we will take a look at the freshly launched 2TB version of the Samsung 850 EVO and 850 Pro. We will put these through the same tests performed on the smaller capacity models. Our hope is to verify that the necessary changes Samsung made to the controller are sufficient to keep performance scaling or at least on-par with the 1TB and smaller models of the same product lines.
