If you somehow felt that there was a test that Al missed while reviewing the OCZ RD400 NVMe SSD, then you have a chance for a second look.  There are several benchmarks which The SSD Review ran which were not covered and they have a different way of displaying data such as latency but the end results are the same, this drive is up there with the Samsung 950 Pro and Intel 750 Series.  Read all about it here.

Introduction, Specifications and Packaging

Introduction:

The OCZ RevoDrive has been around for a good long while. We looked at the first ever RevoDrive back in 2010. It was a bold move for the time, as PCIe SSDs were both rare and very expensive at that time. OCZ's innovation was to implement a new VCA RAID controller which kept latencies low and properly scaled with increased Queue Depth. OCZ got a lot of use out of this formula, later expanding to the RevoDrive 3 x2 which expanded to four parallel SSDs, all the way to the enterprise Z-Drive R4 which further expanded that out to eight RAIDed SSDs.

OCZ's RevoDrive lineup circa 2011.

The latter was a monster of an SSD both in physical size and storage capacity. Its performance was also impressive given that it launched five years ago. After being acquired by Toshiba, OCZ re-spun the old VCA-driven SSD one last time in the form of a RevoDrive 350, but it was the same old formula and high-latency SandForce controllers (updated with in-house Toshiba flash). The RevoDrive line needed to ditch that dated tech and move into the world of NVMe, and today it has!

Here is the new 'Toshiba OCZ RD400', branded as such under the recent rebadging that took place on OCZ's site. The Trion 150 and Vertex 180 have also been relabeled as TR150 and VT180. This new RD400 has some significant changes over the previous iterations of that line. The big one is that it is now a lean M.2 part which can come on/with an optional adapter card for those not having an available M.2 slot.

IDF Shenzhen: Intel Demos 3D XPoint Optane File Copy at 2 GB/s

Subject: Storage | April 14, 2016 - 07:56 PM |
Tagged: Optane, NVMe, Intel, idf

At IDF Shenzhen, Intel talked more about 3D XPoint (spoken cross-point). Initially launched in July of last year, 3D XPoint is essentially a form of phase change memory which has speeds closer to that of DRAM.

It can be addressed at the byte level, unlike flash which transfers in pages (~8KB) and erases in blocks (~6MB). There have been a few demos since the initial launch, and this morning there was another:

Optane demo.png

It is great to see XPoint / Optane technology being demonstrated again, but as far as demos go, this was not the best / fairest example that Intel could have put together. First of all, the 'NAND SSD' they are using is a Thunderbolt 3 connected external, which was clearly bottlenecked badly somewhere else in the chain (when was the last time you saw a 6 Gbit SATA SSD limited to only 283 MB/s?). Also, using SATA for the NAND example while using PCIe x4 NVMe for the Optane example seems a bit extreme to me.

The Optane side of the demo is seen going 1.94 GB/s. That is an impressive figure for sure, but it is important to note that a faster Intel 'NAND SSD' product has already been shipping for over a year:

Yes, the P3700 (reviewed by us here), can reach the speeds seen in this demo, as evidenced by this ATTO run on one of our 1.6TB samples:

Intel DC3700 800GB - atto-4 (driver)--.png

Looking at the P3700 specs, we can see that the 2TB model performs even better and would likely beat the Optane SSD used in today's demo:

P3700 spec.png

Further, in the IDF 2015 demo (where they launched the Optane brand), Intel showed off Optane's random IO performance:

P1020333-.JPG

This demo showed 464,300 4K random IOPS, and if you do the math, that works out to 1.9 GB/s *worth of random IO*, which is far more impressive than sequentials that basically match that of the current generation NVMe product of the same form factor and interface.

I'm still happy to see these demos happen, as it means we are absolutely going to see 3D XPoint in our hands sooner than later. That said, I'd also like to see demos that better demonstrate the strengths of the technology, because if today's demo was comparing apples to apples, it would have shown a P3700 matching the speed of Optane, which does not make the previously stated 1000x speed improvement nearly as obvious as it should be presented.

Micron no longer has NVMe envy

Micron has announced their own PCIe 3.0 NVMe devices today, in HHHL, M.2 and 2.5" form factors.  The specifications are a little sparse at the moment, we do not know the flash which resides within the devices nor the endurance differences between the 7100 PRO series which is designed for read heavy scenarios or the 7100 MAX which is for mixed usage.  In addition to the 7100 series, they also announced the 9100 series which ranges in size from 800GB up to 3.2TB and has theoretical sequential reads of 3GB/s and writes of 2GB/s.  The Register was not provided with any specific pricing but Micron suggested the 7100 series could be priced similarly to SATA drives, while the 9100 series will obviously lie outside the boundaries of Ryan's Law.

You should also take a look at the information Al gathered while he was at the product launch.

"These NVMe SSDs complement Micron's existing S600DC SAS SSDs, which are now shipping in volume. The 7100 is the smaller product and the 9100 its big brother. Both have a PCIe gen 3 NVMe interface, which is faster than the 12 Gbit/s SAS interface used by the S600DC flash drives."

Behold, the spectrum of storage

Tagged: NVMe, SAS, sata, PCIe SSD, low latency

The Register have put together a nice graphic and table displaying current storage technologies and how they relate to each other.  They constructed the graph to demonstrate the major boundaries in storage, between cache/memory, local storage and external storage and how these are going to move thanks to new technology.  NVMe-over-fabric will enable companies to utilize external storage at latencies lower than internal storage that still uses SATA or SAS, with only pure PCIe local storage outpacing its potential.  X-Point, assuming it lives up to the hype, will blur the line between local storage and memory/cache storage, offering latency previously only seen in system memory or on-die cache.

They also provide a table to give you some rough ideas how this translates between storage media, normalizing it a theoretical task which would take L1 cache 1 second to access, this can make it somewhat easier to comprehend for some than nanoseconds.

"Two technology changes are starting to be applied and both could have massive latency reduction effects at the two main storage boundary points: between memory and storage on the one hand, and between internal and external, networked storage on the other."

Seagate to Show 10 GB/s PCIe x16 Flash Drive at OCP Summit

Subject: Storage | March 8, 2016 - 08:07 PM |
Tagged: ssd, Seagate, pcie, NVMe, flash drive

Today Seagate announced that they are production ready on a couple of NVMe PCIe SSD models. These are data-center tailored units that focus on getting as much parallel flash into as small of a space as possible. From engineering drawings, the first appears to be a half height (HHHL) device, communicates over a PCIe 3.0 x8 link, and reaches a claimed 6.7GB/s:

Seagate-6.7GB-Sec-Production-Ready.png

The second model is a bit more interesting for a few reasons. This is a PCIe 3.0 x16 unit (same lane configuration as a high end GPU) that claims 10 GB/s:

Seagate-10GB-Sec-Production-Ready.png

10 GB/s, hmm, where have I seen that before? :)

The second image gives away a bit of what may be going on under that heatsink. There appears to be four M.2 form factor SSDs in there, which would imply that it would appear as four separate NVMe devices. This is no big deal for enterprise data applications that can be pointed at multiple physical devices, but that 10 GB/s does start to make more sense (as a combined total) as we know of no single SSD controller capable of that sort of throughput. It took four Intel SSD 750’s for us to reach that same 10 GB/s figure, so it stands to reason that Seagate would use that same trick, only with M.2 SSDs they can fit everything onto a single slot card.

That’s all we have on this release so far, but we may see some real product pics sneak out of the Open Compute Project Summit, running over the next couple of days.

Full press blast after the break!

10GBps of Non-Volatile Memory Express based storage from Seagate

Subject: General Tech | March 8, 2016 - 06:23 PM |
Tagged: Seagate, PCIe SSD, NVMe

Seagate is rightfully bragging about their new PCIe SSD line up, the fastest currently available.  The drives come in two types, a 16 lane and an 8 lane model, using a standard PCIe interface.  The 16 lane version provides the full theoretical speed of 10GBps while the 8 lane model is less expensive and offers a mere 6.7GBps of throughput.  These drives are designed for enterprise usage but if you can afford the steep price tag which will come with these drives you could certainly using them for an impressive upgrade.  Check out more at The Inquirer.

"SEAGATE HAS announced what the firm claims will be the world's fastest solid state drive (SSD). The 10GBps device is already production-ready and has been built to Open Compute Project (OCP) specifications, making it suitable for hyperscale data centres."

Introduction

NVMe was a great thing to happen to SSDs. The per-IO reduction in latency and CPU overhead was more than welcome, as PCIe SSDs were previously using the antiquated AHCI protocol, which was a carryover from the SATA HDD days. With NVMe came additional required support in Operating Systems and UEFI BIOS implementations. We did some crazy experiments with arrays of these new devices, but we were initially limited by the lack of native hardware-level RAID support to tie multiple PCIe devices together. The launch of the Z170 chipset saw a remedy to this, by including the ability to tie as many as three PCIe SSDs behind a chipset-configured array. The recent C600 server chipset also saw the addition of RSTe capability, expanding this functionality to enterprise devices like the Intel SSD P3608, which was actually a pair of SSDs on a single PCB.

Most Z170 motherboards have come with one or two M.2 slots, meaning that enthusiasts wanting to employ the 3x PCIe RAID made possible by this new chipset would have to get creative with the use of interposer / adapter boards (or use a combination of PCI and U.2 connected Intel SSD 750s). With the Samsung 950 Pro available, as well as the slew of other M.2 SSDs we saw at CES 2016, it’s safe to say that U.2 is going to push back into the enterprise sector, leaving M.2 as the choice for consumer motherboards moving forward. It was therefore only a matter of time before a triple-M.2 motherboard was launched, and that just recently happened - Behold the Gigabyte Z170X-SOC Force!

This new motherboard sits at the high end of Gigabyte’s lineup, with a water-capable VRM cooler and other premium features. We will be passing this board onto Morry for a full review, but this piece will be focusing on one section in particular:

160128-170427.jpg

I have to hand it to Gigabyte for this functional and elegant design choice. The space between the required four full length PCIe slots makes it look like it was chosen to fit M.2 SSDs in-between them. I should also note that it would be possible to use three U.2 adapters linked to three U.2 Intel SSD 750s, but native M.2 devices makes for a significantly more compact and consumer friendly package.

With the test system set up, let’s get right into it, shall we?
