Introduction, Specifications, and Packaging


Everyone expects SSD makers to keep pushing out higher and higher capacity SSDs, but the thing holding them back is sufficient market demand for that capacity. With that, it appears Samsung has decided it was high time for a 4TB model of their 850 EVO. Today we will be looking at this huge capacity point, and paying close attention to any performance dips that sometimes result in pushing a given SSD controller / architecture to extreme capacities.


This new 4TB model benefits from the higher density of Samsung’s 48-layer V-NAND. We performed a side-by-side comparison of 32 and 48 layer products back in March, and found the newer flash to reduce Latency Percentile profiles closer to MLC-equipped Pro model than the 32-layer (TLC) EVO:

We’ll be looking into all of this in today’s review, along with trying our hand at some new mixed paced workload testing, so let’s get to it!

microSD was just a flash in the pan; meet your new tiny storage overlord, Samsung's UFS cards

Subject: General Tech | July 7, 2016 - 12:37 PM |
Tagged: UFS, Samsung, microSD

Samsung just announced the first product based on the new Universal Flash Storage standard which will be making microSD cards as obsolete as your old mix tape.  They will come in sizes from 256GB down to 32GB but it is the speed of these new storage devices that will impress, not the density.  Samsung tells of sequential read speeds of up to 530MB/s, allowing you to dump HD quality video to a PC and random reads of 40,000 IOPS if you have a usage scenario which would read in such a manner.  For recording video you can expect up to 170MB/s sequential write speed or 35,000 random IOPS; 4K drone recordings won't be limited by bandwidth anymore. 

Unfortunately, as The Inquirer points out, no one can use these yet as we haven't a place to stick them.


"What UFS does mean already is that we'll start to see a bottleneck lifted in storage speeds in phones and tablets. As we've already seen, MicroSD doesn't cut it in the speed stakes, and it doesn't seem so long ago that we reported on torn down phones with 'internal' memory that was really just an SD card hidden away."

Mozilla Publishes Servo Nightly (for Mac and Linux)

Subject: General Tech | July 1, 2016 - 07:12 PM |
Tagged: web browser, gecko, servo, Rust, mozilla, Samsung

No love for Windows at the moment, but Mozilla is showing previews of their new browser rendering engine, Servo. This one is developed in Rust, which is a highly parallel yet very memory safe language, which are two great features for a web browser, especially on mobile and multi-core desktops. You are currently able to pick it up on Mac and Linux, although it is not ready to be your primary browser yet. Windows and Android builds “should be available soon”.

Basically, Mozilla has been spending the last few years re-thinking how to design a web browser. Most Web standards are based on assumptions that the browser is going through a main loop, and that these items will occur in sequence. Back in 2013, most of the research was to see far a browser could travel into parallelization before compatibility just stops following. Samsung, who is obviously interested in smartphone technology, partnered with them, because it's easier to add more cores onto a mobile SoC than it is to make existing ones faster.


At the time, they weren't sure whether this research would be used to improve Gecko, the current rendering engine that has been around since Netscape 6, or create a suitable replacement for it. As far as I know, that decision has still not been made, but they also haven't bailed on it yet.

Perhaps we'll see a new wave of Web technology coming soon? Maybe even break up the Webkit monopoly that seems to be forming, led by iOS and Android devices?

Pre and Post Update Testing

Samsung launched their 840 Series SSDs back in May of 2013, which is over three years ago as of this writing. They were well-received as a budget unit but rapidly eclipsed by the follow-on release of the 840 EVO.

A quick check of our test 840 revealed inconsistent read speeds.

We broke news of Samsung’s TLC SSDs being effected by a time-based degrading of read speeds in September of 2014, and since then we have seen nearly every affected product patched by Samsung, with one glaring exception - the original 840 SSD. While the 840 EVO was a TLC SSD with a built-in SLC static data cache, the preceding 840 was a pure TLC drive. With the focus being on the newer / more popular drives, I had done only spot-check testing of our base 840 sample here at the lab, but once I heard there was finally a patch for this unit, I set out to do some pre-update testing so that I could gauge any improvements to read speed from this update.

As a refresher, ‘stale’ data on an 840 EVO would see reduced read speeds over a period of months after those files were written to the drive. This issue was properly addressed in a firmware issued back in April of 2015, but there were continued grumbles from owners of other affected drives, namely the base model 840. With the Advanced Performance Optimization patch being issued so long after others have been patched, I’m left wondering why there was such a long delay on this one? Differences in the base-840’s demonstration of this issue revealed themselves in my pre-patch testing:

Brace Yourselves, Samsung SM961, PM961, 960 PRO and 960 EVO SSDs Are Coming!

Subject: Storage | June 21, 2016 - 04:02 PM |
Tagged: V-NAND, SM961, Samsung, PM961, 960 PRO, 960 EVO, 48-layer

We've known Samsung was working on OEM-series SSDs using their new 48-layer V-NAND, and it appears they are getting closer to shipping in volume, so here's a peek at what is to come:


First up are the SM961 and PM961. The SM and PM appear to be converging into OEM equivalents of the Samsung 'PRO' and 'EVO' retail product lines, with MLC flash present in the SM and TLC (possibly with SLC TurboWrite cache) in the PM. The SM961 has already been spotted for pre-order over at Ram City. Note that they currently list the 1TB, 512GB, and 256GB models, but at the time of this writing, all three product titles (incorrectly) state 1TB. That said, pricing appears to be well below the current 950 PRO retail for equivalent capacities.


These new parts certainly have impressive specs on paper, with the SM961 claiming a 25-50% gain over the 950 PRO in nearly all metrics thanks to 48-layer V-NAND and an updated 'Polaris' controller. We've looked at plenty of Samsung OEM units in the past, and sometimes specs differ between OEM and retail parts, but it is starting to make sense for Samsung to simply relabel a given OEM / retail part at this point (minus any vendor-requested firmware detuning, like reduced write speeds in favor of increased battery life, etc).

With that are the other two upcoming parts that do not appear on the above chart. Those will be the 960 PRO and EVO, barring any last second renaming by Samsung. Originally we were expecting Samsung to add a 1TB SKU to their 950 PRO line, but it appears they have changed gears and will now shift their 48-layer parts to the 960 series. The other big bonus here is that we should also be getting an EVO, which would mark Samsung's first retail M.2 PCIe 3.0 x4 part sporting TLC flash. That product should come in a lot closer to 850 EVO pricing, but offer significantly greater performance over the faster interface. While we don't have specs on these upcoming products, the safe bet is that they will come in very close (if not identical) to that of the aforementioned SM961 and PM961.


Samsung's 48-Layer V-NAND, dissected by TechInsights
(Similar analysis on 32-Layer V-NAND here)

All of these upcoming products are based on Samsung's 48-layer V-NAND. Announced late last year, this flash has measurably reduced latency (thanks to our exclusive Latency Percentile testing) as compared to the older 32-layer parts. Given the performance improvements noted above, it seems that even more can be extracted from this new flash when connected to a sufficiently performant controller. Previous controllers may have been channel bandwidth limited on the newest flash, where Polaris can likely open up the interface to higher speed grades.

We await these upcoming launches with baited breath. It's nice to see these parts inching closer to the saturation point of quad lane PCIe 3.0. Naturally there will be more to follow here, so stay tuned!

Samsung Announces Galaxy S7 Active

Subject: Mobile | June 9, 2016 - 02:20 AM |
Tagged: Samsung, galaxy, galaxy s7, ruggedized

The Samsung Galaxy S7 launched a couple of months ago. While it wasn't too bad from a durability standpoint, I have heard people complain that their screen fractured from a seemingly low-risk fall. Over time, it seemed like they were somewhat fluke examples because it kind-of fell off the radar. Still, if you want the specifications of a Galaxy S7, and you want to extra reliability without placing it inside a case, Samsung has added a version of the phone in their Active line.

AT&T doesn't list pricing and they only state “coming soon” for availability. They do mention that the battery will get a significant bump in capacity, though. The original Galaxy S7 and Galaxy S7 Edge phones have a 3,000 mAh and a 3,700 mAh battery, respectively, but the Galaxy S7 Active is larger: 4,000 mAh. Critics like the battery life of the original S7, many claiming that it lasts a whole, heavy-use day for them, but an extra 33% is nothing to sneer at.

If only it comes to Canada, too...

Samsung Crams Entire 512GB NVMe SSD Into Single BGA Chip Package

Have you ever checked out one of those laptops with the soldered-on eMMC SSD, where the manufacturer was basically checking the 'SSD' box for forgetting the 'Performance' box entirely? What if I told you that it was possible to fit an entire PCIe NVMe SSD with performance comparable to a 950 Pro into a package similar to those eMMC parts?
