Toshiba and Western Digital announce QLC and 96-Layer BiCS Flash

Subject: Storage | June 28, 2017 - 09:49 PM |
Tagged: wdc, WD, toshiba, QLC, nand, BiCS, 96-layer, 3d

A couple of announcements out of Toshiba and Western Digital today. First up is Toshiba announcing QLC (4 bit per cell) flash on their existing BiCS 3 (64-layer) technology. QLC may not be the best for endurance as the voltage tolerances become extremely tight with 16 individual voltage states per cell, but Toshiba has been working on this tech for a while now.

In the above slide from the Toshiba keynote at last year's Flash Memory Summit, we see the use case here is for 'archival grade flash', which would still offer fast reads but is not meant to be written as frequently as MLC or TLC flash. Employing QLC in Toshiba's current BiCS 3 (64-layer) flash would enable 1.5TB of storage in a 16-die stack (within one flash memory chip package).

Next up is BiCS 4, which was announced by Western Digital. We knew BiCS 4 was coming but did not know how many layers it would be. We now know that figure, and it is 96. The initial offerings will be the common 256Gbit (32GB) capacity per die, but stacking 96 cells high means the die will come in considerably smaller, meaning more per wafer, ultimately translating to lower cost per GB in your next SSD.

While these announcements are welcome, their timing and coordinated launch from both companies seems odd. Perhaps it has something to do with this?

Toshiba's new 64 layer NVMe drive takes the cake

Tagged: Toshiba XG5, toshiba, ssd, NVMe, nand, M.2, BiCS, 64-Layer

We first heard about the Toshiba XG5 1TB NVMe SSD at Computex, with its 64 layer BiCS flash and stated read speeds of 3GB/s, writes just over 2 GB/s.  Today Kitguru published a review of the new drive, including ATTO results which match and even exceed the advertised read and write speeds.  Their real world test involved copying 30GB of movies off of a 512GB Samsung 950 Pro to the XG5, only Samsung's new 960 lineup and the OCZ RD400 were able to beat Toshiba's new SSD.  Read more in their full review, right here.

"The Toshiba XG5 1TB NVMe SSD contains Toshiba's newest 3D 64-Layer BiCS memory and our report will examine Toshiba's newest memory, as well as their newest NVMe controller to go along with it."

Here are some more Storage reviews from around the web:

Introduction, Specifications and Packaging

Introduction

Today Intel is launching a new line of client SSDs - the SSD 545S Series. These are simple, 2.5" SATA parts that aim to offer good performance at an economical price point. Low-cost SSDs is not typically Intel's strong suit, mainly because they are extremely rigorous on their design and testing, but the ramping up of IMFT 3D NAND, now entering its second generation stacked to 64-layers, should finally help them get the cost/GB down to levels previously enjoyed by other manufacturers.

diag.jpg

Intel and Micron jointly announced 3D NAND just over two years ago, and a year ago we talked about the next IMFT capacity bump coming as a 'double' move. Well, that's only partially happening today. The 545S line will carry the new IMFT 64-layer flash, but the capacity per die remains the same 256Gbit (32GB) as the previous generation parts. The dies will be smaller, meaning more can fit on a wafer, which drives down production costs, but the larger 512Gbit dies won't be coming until later on (and in a different product line - Intel told us they do not intend to mix die types within the same lines as we've seen Samsung do in the past).

Specifications

specs.png

There are no surprises here, though I am happy to see a 'sustained sequential performance' specification stated by an SSD maker, and I'm happier to see Intel claiming such a high figure for sustained writes (implying this is the TLC writing speed as the SLC cache would be exhausted in sustained writes).

I'm also happy to see sensical endurance specs for once. We've previously seen oddly non-scaling figures in prior SSD releases from multiple companies. Clearly stating a specific TBW 'per 128GB' makes a lot of sense here, and the number itself isn't that bad, either.

Packaging

Simplified packaging from Intel here, apparently to help further reduce shipping costs.

Computex 2017: Toshiba Launches XG5 NVMe Client SSD With 64-Layer BiCS Flash

Subject: Storage | May 30, 2017 - 09:00 AM |
Tagged: toshiba, ssd, ocz, NVMe, nand, M.2, computex 2017, BiCS, 64-Layer

Last night we saw WD launch the first client SSDs with 64-layer NAND Flash, but recall that WD/SanDisk is in partnership with Toshiba to produce this new gen 3 BiCS memory, which means Toshiba is also launching their own product wrapped around this new high-density flash:

XG5_front_angled_2_small.png

Enter the Toshiba XG5. It is certainly coming on strong here, as evidenced by the specs:

specs.png

Unlike the WD/SanDisk launch, the BiCS flash on this Toshiba variant sits behind an NVMe SSD controller, with stated read speeds at 3GB/s and writes just over 2 GB/s. We don't yet have random performance figures, but we expect it to certainly be no slouch given the expected performance of this newest generation of flash memory. Let's take a quick look at some of the high points there:

BiCS.png

Alright, so we have the typical things you'd expect, like better power efficiency and higher endurance, but there is a significant entry there under the performance category - 1-shot, full sequence programming. This is a big deal, since writing to flash memory is typically done in stages, with successive program cycles nudging cell voltages closer to their targets with each pass. This takes time and is one of the main things holding back the write speeds of NAND flash. This new BiCS is claimed to be able to successfully write in a single program cycle, which should translate to noticeable improvements in write latency.

BiCS-FMS.png

Another thing helping with writes is that the XG5 will have its BiCS flash operating in a hybrid mode, meaning these are TLC SSDs with an SLC cache. We do not have confirmed cache sizes to report, but it's a safe bet that they will be similar to competing products.

We don't yet have pricing info, but we do know that the initial capacity offerings will start with 256GB, 512GB, and 1TB offerings. The XG5 is launching in the OEM channel in the second half of 2017. While this one is an OEM product, remember that OCZ is Toshiba's brand for client SSDs, so there's a possibility we may see a retail variant appear under that name in the future.

Press blast after the break.

Computex 2017: Western Digital Launches Client SSDs Sporting 64-Layer NAND

Western Digital bought SanDisk nearly two years ago, but we had not really seen any products jointly launched under both brand labels. Until today:

PRN-Graphic_3D-NAND.jpg

The WD Blue 3D NAND SATA SSD and SanDisk Ultra 3D SSD are both products containing identical internals. Specifically, these are the first client SSDs built with 64-layer 3D NAND technology. Some specs:

  • Sequential read: 560 MB/s
  • Sequential write: 530 MB/s
  • Capacity: 250GB, 500GB, 1TB, 2TB
  • Form factor: 2.5" (WD and Sandisk), M.2 (SATA) 2280 (WD only)

MSRP's start at $99.99 for the 250GB models of all flavors (2.5" / M.2 SATA), and all products will ship with a 3-year warranty.

It might seem odd that we see an identical product shipped under two different brands owned by the same company, but WD is likely leveraging the large OEM relationship held by SanDisk. I'm actually curious to see how this pans out long term because it is a bit confusing at present.

Toshiba Plans To Spin Off Storage Business, Sell 20% Of New Company

Subject: General Tech, Storage | January 29, 2017 - 05:09 PM |
Tagged: toshiba, nand, flash storage, flash memory, business

ZDNet is reporting that Toshiba is in a bit of a financial bind following losses from acquisitions and its Westinghouse division -- which saw massive losses and cost overruns in the US Nuclear market -- which could amount to billions of dollars. In an effort to offset some of those losses and preserve shareholder equity, Toshiba plans to spin off its memory business into a new company and then offer up to a 20% stake in that new company for sale. The new company would include its memory chip and SSD business though its image sensor division would stay with Toshiba and not be part of the spin off.

unnamed.jpg

Toshiba is the second largest memory manufacturer behind Samsung and it is one of the company's most profitable divisions making up the majority of its operating profit.

The company is hoping that other companies or investors will be interested in a piece of that business and that the company will be able to raise enough money from the sale of up to 20% of the spin off company to make up for the losses incurred in its US nuclear market ventures.

Toshiba plans to hold a shareholder meeting in March to seek approval for the plan stating that if it us unable to proceed with the plan and complete a sale to bring in cash by the end of its fiscal year (the end of March), “shareholder equity could be wiped out.”

It is interesting that Toshiba is once again having a bit of corporate drama and needing to restructure (it sold off its PC division in 2015). This could be a good opportunity for one of the smaller memory makers or even one of the spinning rust manufacturers to become more relevant in the flash storage space (and if having a stake got them access to IP for their own stuff even better though that would probably cost them a ton more!). Alternatively, the stake could be bought up by an a large company that just wants a profit machine to grow even larger (heh).

Hopefully the guys will discuss this bit of news on the podcast! What are your thoughts?

Phison Announces UFS 2.1 NAND Controller - Death to eMMC!

Following up on Micron's UFS 2.1 announcement, Phison has announced the launch of their own PS8311 UFS 2.1 controller:

blockdiagram-PS8311.png

For those unaware, UFS 2.1 is a much-anticipated replacement for eMMC, which is the equivalent of trying to run your laptop OS off of an SD Card. Fortunately, eMMC only appears in budget systems, but the transition to UFS 2.1 should bring the storage performance bar up considerably in those systems.

Devices following the Universal Flash Storage standard will enable less protocol overhead and more direct communication with the flash.

Looking at an older roadmap, we see Phison was relatively on target with the PS8311, with a faster PS8313 scheduled for later in 2017.

Press blast after the break.

Introduction, Specifications and Packaging

Introduction

Earlier this year we covered the lower two capacities of the Samsung 750 EVO. We had some requests for a review of the 500GB model as soon as it was added to their lineup, and Samsung promptly sent a sample, but I delayed that review in the interest of getting the full 750 EVO lineup tested under our new storage test suite. I've been running batches of SSDs through this new suite, and we now have enough data points to begin cranking out some reviews. The 750 EVO was at the head of the line, so we will be starting with it first. I'm 'reissuing' our review as a full capacity roundup of the 750 EVO lineup as these are fresh results on a completely new test suite.

160610-145848.jpg

Specifications

specs.png

These are the 'Rev. 2' specifications from Samsung, which include the 500GB model of the 750 EVO. The changes are not significant, mainly a slight bump to random performance of the top capacity model along with a changeover to lower power DDR3 (of twice the capacity) for the 500GB model's system cache.

Packaging

Nothing new here. This is the standard Samsung packaging for their SATA products.
