I'm currently running around at the various briefings and events here at Samsung's Global SSD Summit, but we did get some details on the 960 PRO and EVO that I've set to go live at the NDA time of 1 PM Seoul time.
Here is a distilled version of the specs, capacities, and prices of the 960 PRO and EVO:
- 512GB, 1TB, 2TB capacities
- Sequential: 3.5 GB/s reads / 2.1 GB/s writes
- 4K random (IOPS): 440,000 read / 360,000 write
- Dynamic Thermal Guard (new version of their overtemperature protection - details below)
- 5 year warranty, endurace peaks at 1.2PBW for the 2TB model
- 512GB model = $329.99 ($0.64/GB)
- 250GB, 500GB, 1TB capacities
- Sequential: 3.2 GB/s reads / 1.9 GB/s writes (write speed is for TurboWrite SLC cache)
- 4K random (IOPS): 380,000 read / 360,000 write
- Dynamic Thermal Guard
- 3 year warranty, endurance up to 400TBW for the 1TB model
- 250GB = $129.99 ($0.52/GB)
I would certainly like to see Samsung push the 960 EVO capacities upwards of 4TB, and with competing M.2 NVMe products shipping at a lower cost, those prices use some tweaking as well.
More information and pics to follow later today (tonight for you USA folks)!
**UPDATE** - since everyone is in bed and hasn't read any of this yet, I'm just going to add the information from the presentation here.
First, some of you may be wondering about the inverted capacity difference between the PRO and EVO. Historically, Samsung has shipped their EVO line in higher capacities than the PRO line. The 850 EVO currently ships in capacities up to 4TB, while the 850 PRO remains limited to 2TB. If you look closely at the photos above, you'll note that there are four flash packages on the PRO, while there are only two on the EVO. The cause for this difference is that the DRAM package (visible on the EVO) is integrated within the controller package on the PRO model. This is similar to what Samsung has done with their PM971-NVMe SSD, which has not only the controller and DRAM, but the flash itself all stacked within a *single* package. Samsung calls this package-on-package (PoP):
During the Q&A, Samsung's Unsoo Kim indicated that future 960 EVO's may also shift to the PoP design in order to shift to 4 packages, and therefore double (or quadruple) the capacity on that line in the future.
Samsung also tackled thermal throttling head-on with what they call Dynamic Thermal Guard. This is a combination of a few things. First is the reduced power consumption - the new controller draws ~10% less power despite moving to a 5-core design (up from a 3-core on the 950 PRO). Second, and perhaps more interesting, is a new heat spreading label:
This new label contains a copper layer that helps spread heat across more of the surface area of the M.2 part. Samsung gets bonus points for outside the box thinking there. The combination of the reduced power draw and the heat spreader help to make thermal throttling even more impossible under typical use:
While the above chart was for reads (writes produce more heat), that's still a very good improvement, and being able to move potentially the full drive capacity before throttling is pretty good, especially considering the new models are moving data at a much faster speed. About those faster speeds, here are some increased details on the per-capacity specs:
Take the 960 EVO write specs with a grain of salt - those are assuming writes are going into the SLC cache area but never fear because TurboWrite is getting a boost as well:
This new 'Intelligent TurboWrite' increases the SLC cache area significantly over that of the 850 EVO we are all used to, with up to a 42GB area on the 1TB model! This should make it easier to swallow those boastful write performance claims, as there's a really good chance that all writes any typical user applies to the new EVO will go straight into that new larger cache.
Apologies for the odd cutoffs on these pictures. They were corrected for parallax prior to posting. I also couldn't do anything about the presenter being in the way of the data :). I've requested slides from Samsung and will replace these here if/when they are provided.
Last but not least was a newly announced '2.0' version of the Samsung proprietary NVMe driver, which should help enable these increased speeds, as the Windows InBox driver is certainly not optimized to handle them. With the driver comes a new ground-up redesign of Samsung's Magician software, which added support for file-specific secure erasure and a special 'Magic Vault' secure encrypted area of the SSD that can be invisible to the host OS when locked.
This appears to be the bulk of what is to be announced at the Summit, so for now, I leave you with the endurance ratings and (MSRP) pricing for all capacities / models:

Your humble Storage Editor is once again in Seoul, Korea. With these trips comes unique skylines:
...the Seoul Tower:
...and of course, SSD announcements! Samsung has a habit of slipping product pics into the yearly theme. This year they were a bit more blunt about it:
Yup, looks like tomorrow we will see Samsung officially announce their successor to the 950 PRO. We'll be hearing all about the 960 PRO and the new 960 EVO tomorrow, exactly three months after we broke the early news of these new models.
There will, of course, be more details tomorrow once we attend the relevant product briefings. This will be late at night for those of you back in the states. No further details for now. I'm off to get some dinner and recover from that 14-hour flight!
Introduction, Specifications, and Packaging
It's been quite some time since we saw a true client SSD come out of Intel. The last client product to use their legendary 10-channel controller was the SSD 320 (launched in 2011), and even that product had its foot in the enterprise door as it was rated for both client and enterprise usage. The products that followed began life as enterprise parts and were later reworked for consumer usage. The big examples here are the SATA-based SSD 730 (which began life as the SSD DC S3500/3700), and the PCI/NVMe-based SSD 750 (which was born from the SSD DC P3700). The enterprise hardware had little support for reduced power states, which led Intel to market the 730 as a desktop enthusiast part. The 750 had a great NVMe controller, but the 18-channel design and high idle power draw meant no chance for an M.2 form factor version of the same. With the recent addition of low-cost 3D NAND to their production lines, Intel has now made began another push into the consumer space. Their main client SSD of their new line is the 600p, which we will be taking a look at today:

The Register had a quick chat with Samsung about the Z-SSD they announced at FMS 2016, hoping to get some details from the company about the technology behind the new product, with little success. We know it will be DRAM-NAND gap-filler such as the one Netlist announced earlier and will be possible competition for Intel's XPoint. Samsung did confirm that it will be NVMe and will initially launch as a half height, half length PCIe card, with other interfaces to follow. They did admit it will use 3D V-NAND, but would only hint at the custom circuit design they will use. The Register offers some prognostication at the end of the quick interview, you can see that right here.
"The mysterious Samsung Z-SSD was announced at the Flash Memory Summit, and positioned as a DRAM-NAND gap-filler. This makes it competition for XPoint. We asked Samsung about it, and here is what we learnt."

I visited Phison to check out their new E8 controller:
Phsion opted to take a step back from the higher performance PCIe 3.0 x4 NVMe controllers out there, offering a solution with half the lanes. PCIe 3.0 x2 can still handle 1.5 GB/s, and this controller can exceed 200,000 random IOPS. Those specs are actually in-line with what most shipping x4 solutions offer today, meaning the E8 is more effectively saturating its more limited connectivity. Reducing the number of lanes helps Phison reduce the component cost of this controller to match the cost of typical SATA controllers while tripling the performance, greatly reducing the cost to produce NVMe SSDs.
In addition to 3D Flash support, the E8 is also a DRAM-less controller, meaning it has a small internal SRAM cache and has been architected to not need external DRAM installed on the PCB. DRAM-less means even lower costs. This can only be a good thing, since high performing NVMe parts at SATA costs is going to drive down the costs of even faster NVMe solutions, which is great for future buyers.

Tagged: FMS, FMS 2016, Liqid, kingston, toshiba, phison, U.2, HHHL, NVMe, ssd
A relative newcomer this year at Flash Memory Summit was Liqid. These guys are essentially creating an ecosystem from a subset of parts. Let's start with Toshiba:
At Toshiba's booth, we spotted their XG3 being promoted as being part of the Liqid solution. We also saw a similar demo at the Phison booth, meaning any M.2 parts can be included as part of their design. Now let us get a closer look at the full package options and what they do:
This demo, at the Kingston booth, showed a single U.2 device cranking out 835,000 4k IOPS. This is essentially saturating its PCIe 3.0 x4 link with random IO's, and it actually beats the Micron 9100 that we just reviewed!
How can it pull this off? The trick is that there are actually four M.2 SSDs in that package, along with a PLX switch. The RAID must be handled on the host side, but so long as you have software that can talk to multiple drives, you'll get full speed from this part.
More throughput can be had by switching to a PCIe 3.0 x8 link on a HHHL form factor card:
That's 1.3 million IOPS from a single HHHL device! Technically this is four SSDs, but still, that's impressively fast and is again saturating the bus, but this time it's PCIe 3.0 x8 being pegged!
We'll be tracking Liqid's progress over the coming months, and we will definitely test these solutions as they come to market (we're not there just yet). More to follow from FMS 2016!

Supermicro was at FMS 2016, showing off some of their NVMe chassis:
The first model is the SYS-1028U-TN10RT+. This 1U chassis lets you hot swap 10 2.5" U.2 SSDs, connecting all lanes directly to the host CPUs.
Supermicro's custom PCB and interposer links all 40 PCIe lanes to the motherboard / CPUs.
Need more drives installed? Next up is the SYS-2028U-TN24R4T+, which uses a pair of PCIe switches to connect 24 U.2 SSDs to the same pair of CPUs.
Need EVEN MORE drives installed? The SSG-2028R-NR48N uses multiple switches to connect 48 U.2 SSDs in a single 2U chassis! While the switches will limit the ultimate sequential throughput of the whole package to PCIe 3.0 x40, we know that when it comes to spreading workloads across multiple SSDs, bandwidth bottlenecks are not the whole story, as latency is greatly reduced for a given workload. With a fast set of U.2 parts installed in this chassis, the raw IOPS performance would likely saturate all threads / cores of the installed Xeons before it saturated the PCIe bus!
More to follow as we wrap up FMS 2016!

Microsemi's Flashtec NVMe SSD controllers are now in production, and as Computer Base reports (Google-translated version of the page available here) these controllers use twice as many PCIe lanes than current offerings with a x8 PCI-E 3.0 connection, and can support up to 20 TB of flash capacity.
Image credit: Computer Base
"The NVMe controller destined for the professional high-performance segment and work with PCIe 3.0 x8 or two x4 PCIe 3.0. The NVMe2032 has 32 memory channels (and) NVMe2016 (has) 16. When using 256-Gbit flash SSDs can be implemented with up to 20 terabytes of storage."
The 32-channel NVMe2032 boasts up to 1 million IOPS in 4K random read performance, and the controller supports DDR4 memory for faster cache performance. The announcement of the availability of these chips comes just before the start of Flash Memory Summit, which our own Allyn Malventano will be attending. Stay tuned for more flashy SSD news to come!
Yes, you read that correctly the 480GB Sonix NVMe PCIe SSD is indeed a Zotac product, the internals will be a bit less surprising to you however. Inside is a Phison PS5007-11 controller, paired with Toshiba MLC NAND and a 512MB DDR3 cache. Along with benchmarking the drive, eTeknix exposed its innards for your viewing pleasure in their full review. The price is a hair under $1/GB, perhaps a little less expensive than other PCIe SSD cards but still far above SATA based SSDs.
"We have finally entered the new storage era and it is no longer just a few selected manufacturers that have NVMe drives on the market. More competition and more options are great for us consumers and it is a pleasure for me to take Zotac’s Sonix PCIe-based NVMe SSD with 480GBcapacity for a test drive here at the office today."

Introduction, Specifications and Packaging
It's been too long since we took a look at enterprise SSDs here at PC Perspective, so it's high time we get back to it! The delay has stemmed from some low-level re-engineering of our test suite to unlock some really cool QoS and Latency Percentile possibilities involving PACED workloads. We've also done a lot of work to distill hundreds of hours of test results into fewer yet more meaningful charts. More on that as we get into the article. For now, let's focus on today's test subject:
Behold the Micron 9100 MAX Series. Inside that unassuming 2.5" U.2 enclosure sits 4TB of flash and over 4GB of DRAM. It's capable of 3 GB/s reads, 2 GB/s writes, and 750,000 IOPS. All from inside that little silver box! There's not a lot more to say here because nobody is going to read much past that 3/4 MILLION IOPS figure I just slipped, so I'll just get into the rest of the article now :).
The 9100's come in two flavors and form factors. The MAX series (1.2TB and 2.4TB in the above list) come with very high levels of performance and endurance, while the PRO series comes with lower overprovisioning, enabling higher capacity points for a given flash loadout (800GB, 1.6TB, 3.2TB). Those five different capacity / performance points are available in both PCIe (HHHL) and U.2 (2.5") form factors, making for 10 total available SKUs. All products are PCIe 3.0 x4, using NVMe as their protocol. They should all be bootable on systems capable of UEFI/NVMe BIOS enumeration.
Idle power consumption is a respectable 7W, while active consumption is selectable in 20W, 25W, and 'unlimited' increments. While >25W operation technically exceeds the PCIe specification for non-GPU devices, we know that the physical slot is capable of 75W for GPUs, so why can't SSDs have some more fun too! That said, even in unlimited mode, the 9100's should still stick relatively close to 25W and in our testing did not exceed 29W at any workload. Detailed power testing is coming to future enterprise articles, but for now, the extent will be what was measured and noted in this paragraph.
Our 9100 MAX samples came only in anti-static bags, so no fancy packaging to show here. Enterprise parts typically come in white/brown boxes with little flair.
