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!

..now this picture has been corrected for extreme parallax and was taken in far from ideal conditions, but you get the point. Samsung's keynote is coming up later today, and I have a hunch this will be a big part of what they present. We did know 64-Layer was coming, as it was mentioned in Samsung's last earnings announcement, but confirmation is nice.
*edit* now that the press conference has taken place, here are a few relevant slides:
With 48-Layer V-NAND announced last year (and still rolling out), it's good to see Samsung pushing hard into higher capacity dies. 64-Layer enables 512Gbits (64GB) per die, and 100MB/s per die maximum throughput means even lower capacity SSDs should offer impressive sequentials.

We will know more shortly, but for now, dream of even higher capacity SSDs :)
*edit* and this just happened:
*additional edit* - here's a better picture taken after the keynote:
The 32TB model in their 2.5" form factor displaces last years 16TB model. The drive itself is essentially identical, but the flash packages now contain 64-layer dies, doubling the available capacity of the device.

Tagged: FMS 2016, ssd, Seagate, Lightning, facebook, 60TB
Seagate showed off some impressive Solid State Storage at Flash Memory Summit 2016.
First up is the Nytro XM1440. This is a 2TB M.2 22110 SSD complete with enterprise firmware and power loss protection. Nice little package, but what's it for?
..well if you have 60 of them, you can put them into this impressive 1U chassis. This is Facebook's Lightning chassis (discussed yesterday). With Seagate's 2TB parts, this makes for 120TB of flash in a 1U footprint. Great for hyperscale datacenters.
Now onto what you came to see:
This is the 'Seagate 60TB SAS SSD'. It really doesn't need a unique name because that capacity takes care of that for us! This is a 3.5" form factor SAS 12Gbit beast of a drive.
They pulled this density off with a few tricks which I'll walk through. First was the stacking of three PCBs with flash packages on both sides. 80 packages in total.
Next up is Seagate's ONFi fan-out ASIC. This is required because you can only have so many devices connected to a single channel / bus of a given SSD controller. The ASIC acts as a switch for data between the controller and flash dies.
With so much flash present, we could use a bit of fault tolerance. You may recall RAISE from SandForce (who Seagate now owns). This is effectively RAID for flash dies, enabling greater resistance to individual errors across the array.
Finally we have the specs. With a dual 12 Gbit SAS inteface, the 60TB SAS SSD can handle 1.5 GB/s reads, 1.0 GB/s writes, and offers 150,000 IOPS at 4KB QD32 random (SAS tops out at QD32). The idea behind drives like these is to cram as much storage into the smallest space possible, and this is certainly a step in the right direction.
We also saw the XP7200 add-in card. I found this one interesting as it is a PCIe 3.0 x16 card with four M.2 PCIe 3.0 x4 SSDs installed, but *without* a PLX switch to link them to the host system. This is possible only in server systems supporting PCIe Bifurcation, where the host can recognize that certain sets of lanes are linked to individual components.

Just because you are on the road there is no reason to subject yourself to HDD speeds when transferring files. Not only will an SSD be quieter and more resilient but the USB 3.1 Gen 1 Type C port theoretically offers up to 450MB/s transfer speeds. This particular 2TB portable SSD uses the same MGX controller as the 850 EVO, the NAND is Samsung's 48-layer TLC V-NAND. The Tech Report previously tried out the T1 model so their expectations were that this drive would improve performance in addition to offering larger sizes of drive. Does it live up to expectations? Find out in their full review.
"Not all new SSDs go inside your computer. We take a quick look at Samsung's latest V-NAND-powered external drive, the Portable SSD T3, to see what it's like to put 2TB of fast storage in one's pocket."

Tagged: XPoint, Worm, storage, ssd, RocksDB, Optane, nand, flash, facebook
At their FMS 2016 Keynote, Facebook gave us some details on the various storage technologies that fuel their massive operation:
In the four corners above, they covered the full spectrum of storing bits. From NVMe to Lightning (huge racks of flash (JBOF)), to AVA (quad M.2 22110 NVMe SSDs), to the new kid on the block, WORM storage. WORM stands for Write Once Read Many, and as you might imagine, Facebook has lots of archival data that they would like to be able to read quickly, so this sort of storage fits the bill nicely. How do you pull off massive capacity in flash devices? QLC. Forget MLC or TLC, QLC stores four bits per cell, meaning there are 16 individual voltage states for each cell. This requires extremely precise writing techniques and reads must appropriately compensate for cell drift over time, and while this was a near impossibility with planar NAND, 3D NAND has more volume to store those electrons. This means one can trade the endurance gains of 3D NAND for higher bit density, ultimately enabling SSDs upwards of ~100TB in capacity. The catch is that they are rated at only ~150 write cycles. This is fine for archival storage requiring WORM workloads, and you still maintain NAND speeds when it comes to reading that data later on, meaning that decade old Facebook post will appear in your browser just as quickly as the one you posted ten minutes ago.
Next up was a look at some preliminary Intel Optane SSD results using RocksDB. Compared to a P3600, the prototype Optane part offers impressive gains in Facebook's real-world workload. Throughput jumped by 3x, and latency reduced to 1/10th of its previous value. These are impressive gains given this fairly heavy mixed workload.

Tagged: XPoint, QuantX, nand, micron
Micron just completed their keynote address at Flash Memory Summit, and as part of the presentation, we saw our first look at some raw scaled Queue Depth IOPS performance figures from devices utilizing XPoint memory:
These are the performance figures from an U.2 device with a PCIe 3.0 x4 link. Note the outstanding ramp up to full saturation of the bus at a QD of only 4. Slower flash devices require much more parallelism and a deeper queue to achieve sufficient IOPS throughput to saturate that same bus. That 'slow' device on the bottom there, I'm pretty certain, is Micron's own 9100 MAX, which was the fastest thing we had tested to date, and it's being just walked all over by this new XPoint prototype!
Ok, so that's damn fast, but what if you had an add in card with PCIe 3.0 x8?
Ok, now that's just insane! While the queue had to climb to ~8 to reach these figures, that's 1.8 MILLION IOPS from a single HHHL add in card. That's greater than 7 GB/s worth of 4KB random performance!
In addition to the crazy throughput and IOPS figures, we also see latencies running at 1/10th that of flash-based NVMe devices.
..so it appears that while the cell-level performance of XPoint boasts 1000x improvements over flash, once you implement it into an actual solution that must operate within the bounds of current systems (NVMe and PCIe 3.0), we currently get only a 10x improvement over NAND flash. Given how fast NAND already is, 10x is no small improvement, and XPoint still opens the door for further improvement as the technology and implementations mature over time.

One version of the UFS 2.1 devices also contains Micron's first packaged offering of LPDDR4X. This low power RAM offers an additional 20% power savings over existing LPDDR4.

Tagged: ssd, Samsung, enterprise ssd
Allyn first mentioned this device last year, but they're apparently now shipping for a whopping $10,000 USD. To refresh, the PM1633a is an SSD from Samsung that packs 15.36TB into a 2.5-inch form factor. According to Samsung, it does this by stacking 16 dies, each containing 48 layers of flash cells, into a 512GB package.
It's unclear how many packages are installed in the device, because we don't know how much over-provisioning Samsung provides, but the advertised capacity equates to exactly 30 packages. Update @ 11:30pm: Turns out I was staring right at it in the old press release. The drive has 32 packages, so 16384 GB, once you account for over-provisioning.

Down at CDW, they are selling them for $10,311.99 USD with the option to lease for $321.73 / month. That's only 2.1c/GB... per month... for probably three whole years. No Ryan, that doesn't count. The warranty period doesn't seem to be listed, but Samsung will cover up to 15.36TB per day in writes. I mean, we knew it would be expensive, given its size and performance. At least it's only ~65c/GB.

Plextor announced their first M.2 SSD at CES 2016, and now the M8Pe series is officially set for a release this month. Computer Base (German language) had a chance to preview the new drive, and supplied a detailed look at the M.2 version (this is model M8PeG, and the version with a riser card is M8PeY).
The Plextor M8PeG SSD (Image credit: Computer Base)
Even the M.2 form-factor version of the SSD includes a heatsink, which Plextor warns creates incompatibility with notebooks as the M8PeG is 4.79 mm in height with the heatsink in place.
Specifications for the drives are as follows:
|Plextor M8PeG||Plextor M8PeY|
|Controller||Marvell 88SS1093 (8-Channel)|
|DRAM||512MB LPDDR3 (1024MB variant)|
|Capacity||128 GB, 256 GB, 512 GB|
|NAND||Toshiba 15nm Toggle 2.0 MLC|
|Form Factor||M.2 (80 mm)||PCIe card (HH, HL)|
|Interface||PCIe 3.0 x4|
So what did Computer Base have to report with their hands-on preview of the new drive? Here's their CrystalDiskMark result:

Tagged: MX300, micron, M.2, crucial, 525GB, 275GB, 1TB
We reviewed the Crucial MX300 750GB SSD a few months back. It was a good drive that tested well, and thanks to its IMFT 3D NAND, it came in at a very competitive price point. Today Crucial has rearranged that lineup a bit:
The following capacities are being added to the MX300 lineup:
- 1TB $260 ($0.26/GB)
- 525GB $130 ($0.25/GB)
- 275GB $70 ($0.25/GB)
- 275GB * M.2 2280
The new capacities will be what is sold moving forward (starting 'late August'), with the 750GB model shifting to 'Limited Edition' status. That $0.25/GB carrying all the way down to the lowest capacity is significant, as typically we see higher cost/GB due to controller/PCB/packaging have more impact. Without that coming into play, we get a nearly 300GB SSD coming in at $70!
Specs and expected performance remain the same across all capacities, save a dip in random read performance on the 275GB models, mainly due to the reduced die count / parallelism. We'll take a look at these new capacities just as soon as samples arrive.

LaCie's newest external drive is called the Porsche Design Desktop Drive and comes in 4, 5 and 8TB models, giving you plenty of room to back up important files and to take your stories with you when travelling. It connects via Type-C USB 3.1, finally giving you a peripheral to plug into that port on your motherboard although it requires an AC power adapter to be plugged in when in use. Benchmark Reviews tested the drive and saw reads and writes hitting just under 180MB/s which is not bad, although far short of the theoretical maximum performance of the new USB protocol. You can check out the full review here.
"Utilizing the latest USB-C connector and providing up to 8GB of storage as well as simultaneously charging your laptop computer, the LaCie Porsche Design Desktop Drive is powerful, stylish, and usable with any computer with a USB 3.0/3.1 port.

If you are looking for large sized storage and can accept the SATA 6Gbps bottleneck, the 1920GB Toshiba HK4R SATA SSD certainly has some room for files. It uses Toshiba's own TC58 controller with 15nm MLC NAND and sports an endurance rating of 1 Drive Write Per Day for the duration of the 5 year warranty or up to 3520TB written. The testing done at The SSD Review showed sequential read and write speeds of 524MB/s and 503MB/s respectively making the drive a great choice for consumers or enterprise as the drive has many features required in the data centre. There is a distinct lack of pricing information, we shall see what these drives sell at some time in the near future.
"SATA SSDs are all the rage in data centers. Unlike their PCIe bothers, these SATA SSDs don’t often need to have high endurance figures and lightning fast IOPS performance. Instead, they typically just need to be cheap, reliable, and what is becoming more important lately, high capacity."

He, and his co-hosts, talk about their experiences with the medium, such as using a two-deck cassette player to copy programs and share them with friends. It doesn't go too deep into the technology or the time period, unlike some of his previous videos, but it's still entertaining none-the-less.

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.
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!
