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:

DSC06006.jpg 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 850 EVO now comes in M.2 flavour too

As Al's review of the 850 EVO exists in a cat like superposition of being biased both for and against Samsung, perhaps you would like a second opinion.  That is where The Tech Report's review comes in handy, which was published just a few short hours ago.  Their findings were perfectly in line with the others, exactly the same performance as the 2.5" drives but in a nice bite sized form factor.  The only drawback is the size, the new M.2's are missing the 1TB model at the moment.


"Samsung's 850 EVO SSD debuted in December inside the usual 2.5" case. Now, the drive is spreading to smaller mSATA and M.2 form factors. We've examined the new drives to see how the mini lineup compares to its full-sized forbear."

Introduction, Specifications and Packaging


Following the same pattern that Samsung led with the 840 Pro and 840 EVO, history has repeated itself with the 850 Pro and 850 EVO. With the 850 EVO launching late last year and being quite successful, it was only a matter of time before Samsung expanded past the 2.5" form factor for this popular SSD. Today is that day:


Today we will be looking at the MSATA and M.2 form factors. To clarify, the M.2 units are still using a SATA controller and connection, and must therefore be installed in a system capable of linking SATA lanes to its M.2 port. As both products are SATA, the DRAM cache based RAPID mode included with their Magician value added software is also available for these models. We won't be using RAPID for this review, but we did take a look at it in a prior article.

Given that 850 EVOs use VNAND - a vastly different technology than the planar NAND used in the 840 EVO, we suspect it is not subject to the same flash cell drift related issues (hopefully to be corrected soon) in the 840 EVO. Only time will tell for sure on that front, but we have not see any of those issues present in 850 EVO models since their launch.

Samsung sampled us the M.2 SATA in 120GB and 500GB, and the MSATA in 120GB and 1TB. Since both are SATA-based, these are only physical packaging differences. The die counts are the same as the 2.5" desktop counterparts. While the pair of 120GB models should be essentially identical, we'll throw both in with the results to validate the slight differences in stated specs below.

Don't forget the 1TB Crucial BX100 costs less than $400

It has been about a week since Al posted his review of the 256GB and 512GB models of the Crucial BX100 and what better way to remind you than with a review of the 1TB model, currently a mere $380 on Amazon (or only $374 on!).  Hardware Canucks cracked open the 1TB budget priced consumer level SSD for your enjoyment right here, as well as running it through a gamut of tests. As expected their results are in line with the 512GB model as they both use a 4 channel controller, which does mean they are slower than some competitors drives.  On the other hand the BX100 also has a significantly lower price making the 1TB model much more accessible for users.  Check out their post here.


"Crucial's BX100 combines performance, endurance and value into one awesome budget-friendly SSD The best part? The 1TB version costs just $400."

Given that we are anticipating a launch of the Samsung 850 EVO very shortly, it is a good time to back fill on the complete performance picture of the 850 Pro series. We have done several full capacity roundups of various SSD models over the past months, and the common theme with all of them is that as the die count is reduced in lower capacity models, so is the parallelism that can be achieved. This effect varies based on what type of flash memory die is used, but the end result is mostly an apparent reduction in write performance. Fueling this issue is the increase in flash memory die capacity over time.


There are two different ways to counteract the effects of write speed reductions caused by larger capacity / fewer dies:

  • Reduce die capacity.
  • Increase write performance per die.

Recently there has been a trend towards *lower* capacity dies. Micron makes their 16nm flash in both 128Gbit and 64Gbit. Shifting back towards the 64Gbit dies in lower capacity SSD models helps them keep the die count up, increasing overall parallelism, and therefore keeping write speeds and random IO performance relatively high.

Introduction, Specifications and Packaging


It seems a lot of folks have been incorporating Silicon Motion's SM2246EN controller into their product lines. We first reviewed the Angelbird SSD wrk, but only in a 512GB capacity. We then reviewed a pair of Corsair Force LX's (256GB and 512GB). ADATA has joined the club with their new Premier SP610 product line, and today we are going to take a look at all available capacities of this new model:


It's fortunate that ADATA was able to sample us a full capacity spread, as this will let us evaluate all shipping SSD capacites that exist for the Silicon Motion SM2246EN controller.

Introduction, Specifications and Packaging


A few months back, we took a look at the ADATA Premier Pro SP920 series of SSDs. Those came equipped with the Marvell 88SS9189 controller. Marvell SSD controllers have always done a good job, and they were among the first to support SATA 6Gbit speeds. Crucial was one of the first to adopt the Marvell controller into their SATA SSD products, so it seems fitting that we revisit the 88SS9189 controller in the form of Micron's Crucial M550 Series of SSDs:


Being one of the big manufacturers of SSDs, Micron has some cool production videos. Here's one of their videos covering the production of flash all the way through to the assembly of an SSD. We actually toured one of these plants a few years back. Good stuff:

A couple of really nice Amazon picks hit my email box today and I thought they were worth posting for our readers as well.


1TB Samsung 840 EVO for $399

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!


ASUS PB287Q 4K 28-in monitor for $649

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.

The Samsung 840 goes mSATA in a big way

Subject: General Tech | December 31, 2013 - 07:00 PM |
Tagged: ssd, msata, Samsung 840, 1TB

The new Samsung 840 EVO mSATA SSD has arrived with 1TB of storage at a price comparable to the existing 2.5" form.  This different way to connect an SSD will not be with us long as M.2 starts to be adopted but currently offers the same benefits as the full sized connection you are more familiar with.  From the tests conducted at SSD Review you can see that this would be a great update to a laptop which possesses an mSATA slot and will greatly improve performance.  While endurance is possibly a concern the fact that Samsung offers a 3 year warranty should assuage your worries somewhat.


"There is no doubt in anyones mind that 2014 will be the year of the M.2/NGFF SSD, however, Samsung is about to release an SSD that is guaranteed to rock the SSD community like few others have. This SSD is the Samsung 840 EVO 1TB mSATA SSD and it, not only is the one and only mSATA SSD capable of 1TB storage available in the world, but also, Samsung has priced this SSD at only $10 higher than it’s sister 1TB notebook form factor SSD. To say that there are more than a few mSATA SSD storage based notebook owners that have been waiting for some time for exactly this type of capacity is an understatement; Lenovo Thinkpad sales surpassed the 60 million mark some time ago."
