Earlier this week Samsung announced that it has begun mass production on its first consumer solid state drive based on QLC (4 bits per cell) V-NAND. According to the company, the initial drives will offer 4TB capacities and deliver equivalent performance to Samsung’s TLC offerings along with a three year warranty.

Samsung claims that its fourth generation V-NAND flash in QLC mode (with 16 voltage states) with 64 layers is able to offer up to 1Tb per chip. The 4TB SATA SSD uses a 3-bit SSD controller, TurboWrite technology, and 32 1Tb QLC V-NAND chips and thanks to the write cache (running the V-NAND in SLC or MLC modes) Samsung is able to wring extra performance out of the drive though it’s obviously limited ultimately by the SATA interface. Specifically, Samsung is promising sequential reads of 540 MB/s and sequential writes of up to 520 MB/s with the new QLC SSD. For comparison, Samsung’s fourth generation V-NAND operating in TLC mode is able to offer up to 256Gb and 512Gb capacities depending on package. Moving to fifth generation V-NAND in TLC mode Samsung is offering 256Gb per chip capacities (using 96 layers). Scouring the internet, it appears that Samsung has yet to reveal what it expects to achieve from 5th generation V-NAND in QLC mode. It should be able to at least match the 1Tb of 4th generation QLC V-NAND with the improved performance and efficiencies of the newer generation (including the faster Toggle DDR 4.0 interface) though I would guess Samsung could get more, maybe topping out at as much as 1.5Tb (eventually and if they use 96 layers--I was finding conflicting info on this). In any event, for futher comparison, Intel and Micron have been able to get 1Tb QLC 3D NAND flash chips and Western Digital and Toshiba are working on 96 Layer BiCS4 which is expected to offer up to 1.33Tb capacities when run in 4-bits per cell mode (QLC).

It seems that Samsung is playing a bit of catch up when it comes to solid state storage using QLC though they do still have a bit of time to launch products this year along with the other players. Samsung claims that it will launch its 4TB 2.5” consumer SSD first with 1TB and 2TB models to follow later this year.

Interestingly (and more vaguely), Samsung mentioned in its press release that it plans to begin rolling out M.2 SSDs for the enterprise market and that it will begin mass producing fifth generation 4-bit V-NAND later this year.

I am looking forward to more details on Samsung’s plans for QLC and especially on the specifications of fifth generation 4-bit V-NAND and the drives that it will enable for both consumer systems and the data center markets.

What are your thoughts on Samsung’s QLC V-NAND?

Your Android may suffer a Meltdown

Researchers in Austria have found a way to utilize Meltdown to hack Galaxy S7 smartphones, a bad sign for security.  It was previously discovered that ARM's Cortex A75 was susceptible to the vulnerability but this is the first time we have seen this exploit successfully used on a Snapdragon 820 or Exynos 8890 chipset.  Even better is that these researchers have discovered variants which can affect older chipsets, meaning that far more phones may be vulnerable than we ever imagined.  You can take a peek over at The Inquirer, if you are looking to ruin your day.

64 layers of EVOlutionary growth from Samsung

Tagged: 860 evo, Samsung, sata, ssd, 64-layer TLC

Samsung have updated their popular SATA SSD series with 64-layer TLC and The Tech Report takes a look at it here.   As you may remember from Al's review back in January, the drive did not show real improvements over the 850 EVO and was occasionally slower at certain tasks.  It has been a while, so has the performance changed over time?  Find out in the full review.

The whole DRAM market is changing

Subject: General Tech | July 26, 2018 - 12:58 PM |
Tagged: SK Hynix, Samsung, micron, DRAM

According to this story out of DigiTimes we may finally be hitting peak DRAM demand and that supplies and prices may start to decline.  This seems somewhat counter intuitive, the drop in sales of smartphones and cryptomining will reduce the demand somewhat but we should expect to see a surge in demand from auto manufacturers as our cars become more and more complex ... and possibly intelligent.  The counterpoint would be the maturation of current process tech and the numerous plants coming online over the next year or so.  Samsung, Micron, SK Hynix, Innotron and even Jin Hua will be facing a lot of changes over the coming months.  Let us hope part of the changes are a downwards trend in price.

"Samsung Electronics and SK Hynix would be forced to overhaul their current profit-oriented business strategy as both firms believe that the booming memory market, which has continued for 2-3 years, is likely to be over by the end of 2018, according to a Korea-based Digital Times report."

Notice a big data bill and a bunch of the photos on your Samsung device are now all over the internet?

Tagged: Samsung, samsung messenger, oops

The newer models of Samsung mobile devices feature an interesting ability, they can send your entire gallery of pictures to contacts on your Samsung Messenger app, without your knowledge or consent.  Samsung has yet to admit there is an error, let alone release a fix for this new feature but The Inquirer offers you a workaround.  In the settings of your Samsung Messenger app, disable the apps ability to access your phone's storage; this will prevent you from sending pictures you intended to send but it is probably best for everyone if you do this until a fix is release.

"The Samsung Galaxy S9, Galaxy S9+ and Note 8 have all shown evidence of the glitch, which is causing the Samsung Messages app to send photos - sometimes one, sometimes the entire ruddy gallery - on, sometimes before you've even noticed it's happening."

Samsung's C32HG70, FreeSync + HDR = FreeSync 2

Subject: Displays | June 20, 2018 - 03:54 PM |
Tagged: C32HG70, Samsung, freesync, freesync 2, hdr, quantum dots, 144hz

There is a lot to parse in Guru 3D's review of the Samsung C32HG70 a 32", 1440p, 144Hz curved VA panel as they delve into details about HDR and FreeSync as well as discussing the merits of 4k versus 2560x1440 or 3440x1440.  If you are already familiar with those topics you can jump into the meat of their review of this impressive panel.  The display offers great SDR performance but truly shines when you enable HDR and install the latest firmware updates, after which you can test your experience in Ultimate FreeSync which offers a dynamic range of 48-144Hz or in Standard which limits the range to 120-144Hz to prevent tearing which might occur in some setups.   There is a lot to go through in this review, so you might as well get started.

"This Quantum Dot 2560x1440 monitor can do 144Hz combined with FreeSync and FreeSync2. That eliminates stutter and tearing while gaming in HDR. The Samsung C32HG70 is fitted with a VA panel offering proper image quality, connectivity, and features."

Why we can't have nice things, part infinity ... Samsung escapes security support

Subject: General Tech | June 1, 2018 - 12:41 PM |
Tagged: Samsung, security, lawyers

It is unlikely you spend much time following Dutch court cases; thankfully The Register had an ear out though as this particular case is of interest to many.  The Dutch Consumers Association launched a case which would have made Samsung legally responsible for providing security updates to phones for up to four years after launch, two years after sale.  A judgment in favour of this would have meant an appeal, of course, but could eventually have meant Android updates for all as it would be a bizarre decision on Samsung's part to geographically limit security updates.  We should expect to see more cases, hopefully somewhere is a judge that does not consider a maximum of six years of security updates unacceptably onerous for Samsung to provide.

"The case could have had far-reaching impacts, since there's little point in writing software for only one market. The Consumentenbond wanted the court to force the smartphone giant to provide security updates for four years after a product was launched, and/or two years after a product was sold."

Samsung Updates 2018 QLED TVs with FreeSync Support

Subject: Displays | May 23, 2018 - 01:43 PM |
Tagged: Samsung, qled, Predator X27, hdr. g-sync, freesync

Hot on the heels of the pricing and pre-order availability of the first G-SYNC HDR displays, we have news on more support for FreeSync, this time expanding to TVs.

Today, popular TV review site Rtings posted confirmation that the latest firmware (1103), released on May 21st, in fact, enables support for FreeSync on Q6FN, Q7FN, Q8FN, Q9FN, and NU8000 sets. We have no official confirmation that this is FreeSync 2 support, but all signs point to this being the case.

Given how well the 2018 QLED sets fair in Rtings own reviews, including HDR performance, this could be the first product to be released combining high-end HDR with variable refresh technology.

Interestingly enough, you can currently pick up the 55" Samsung Q7F TV for around $1700, which translates to $300 less than the 27" Acer Predator X27 G-SYNC HDR display available for preorder now. While it would be difficult to fit a 55" display on your desk, it's an interesting comparison nonetheless.

If you happen to own one of these compatible TVs, you can find the firmware to enable FreeSync on Samsung's support page for your given model. For the rest of us, we'll be waiting for reputable outlets like Rtings to conduct their standard through testing of this new feature!
