According to an HGST press release, the company will bring an SSD based on phase change memory to the 2014 Flash Memory Summit in Santa Clara, California. They claim that it will actually be at their booth, on the show floor, for two days (August 6th and 7th).
The device, which is not branded, connects via PCIe 2.0 x4. It is designed for speed. It is allegedly capable of 3 million IOPS, with just 1.5 microseconds required for a single access. For comparison, the 800GB Intel SSD DC P3700, recently reviewed by Allyn, had a dominating lead over the competitors that he tested. It was just shy of 250 thousand IOPS. This is, supposedly, about twelve times faster.
While it is based on a different technology than NAND, and thus not directly comparable, the PCM chips are apparently manufactured at 45nm. Regardless, that is significantly larger lithography than competing products. Intel is manufacturing their flash at 20nm, while Samsung managed to use a 30nm process for their recent V-NAND launch.
What does concern me is the capacity per chip. According to the press release, it is 1Gb per chip. That is about two orders of magnitude smaller than what NAND is pushing. That is, also, the only reference to capacity in the entire press release. It makes me wonder how small the total drive capacity will be, especially compared to RAM drives.
Of course, because it does not seem to be a marketed product yet, nothing about pricing or availability. It will almost definitely be aimed at the enterprise market, though (especially given HGST's track record).
*** Update from Allyn ***
I'm hijacking Scott's news post with photos of the actual PCM SSD, from the FMS show floor:
In case you all are wondering, yes, it does in fact work:
One of the advantages of PCM is that it is addressed at smaller sections as compared to typical flash memory. This means you can see ~700k *single sector* random IOPS at QD=1. You can only pull off that sort of figure with extremely low IO latency. They only showed this output at their display, but ramping up QD > 1 should reasonably lead to the 3 million figure claimed in their release.

Marvell is notorious for being the first to bring a 6Gb/sec SATA controller to market, and they continue to do very well in that area. Their very capable 88SS9189 controller powers the Crucial MX100 and M550, as well as the ADATA SP920.
Today they have announced a newer controller, the 88SS1093. Despite the confusing numbering, the 88SS1093 has a PCIe 3.0 x4 host interface and will support the full NVMe protocol. The provided specs are on the light side, as performance of this controller will ultimately depend on the speed and parallelism of the attached flash, but its sure to be a decent performer. I suspect it would behave like their SATA part, only no longer bottlenecked by SATA 6Gb/sec speeds.
More to follow as I hope to see this controller in person on the exhibition hall (which opens to press in a few hours). Full press blast after the break.
*** Update ***
Apologies as there was no photo to be taken - Marvell had no booth at the exibition space at FMS.

Just minutes ago at the Flash Memory Summit, Samsung announced the production of 32-layer TLC VNAND:
This is the key to production of a soon-to-be-released 850 EVO, which should bring the excellent performance of the 850 Pro, with the reduced cost benefit we saw with the previous generation 840 EVO. Here's what the progression to 3D VNAND looks like:
3D TLC VNAND will look identical to the right most image in the above slide, but the difference will be that the charge stored has more variability. Given that Samsung's VNAND tech has more volume to store electrons when compared to competing 2D planar flash technology, it's a safe bet that this new TLC will come with higher endurance ratings than those other technologies. There is much more information on Samsung's VNAND technology on page 1 of our 850 Pro review. Be sure to check that out if you haven't already!
Another announcement made was more of an initiative, but a very interesting one at that. SSDs are generally dumb when it comes to coordinating with the host - in that there is virtually no coordination. An SSD has no idea which pieces of files were meant to be grouped together, etc (top half of this slide):
Stuff comes into the SSD and it puts it where it can based on its best guess as to how it should optimize those writes. What you'd want to have, ideally, is a more intelligent method of coordination between the host system and the SSD (more like the bottom half of the above slide). Samsung has been dabbling in the possibilities here and has seen some demonstrable gains to be made. In a system where they made the host software aware of the SSD flash space, and vice versa, they were able to significantly reduce write latency during high IOPS activity.
The key is that if the host / host software has more control over where and how data is stored on the SSD, the end result is a much more optimized write pattern, which ultimately boosts overall throughput and IOPS. We are still in the experimentation stage on Storage Intelligence, with more to follow as standards are developed and the industry pushes forward.
It might be a while before we see Storage Intelligence go mainstream, but I'm definitely eager to see 3D TLC VNAND hit the market, and now we know it's coming! More to follow in the coming days as we continue our live coverage of the Flash Memory Summit!

Intel has not offered many products which take advantage of their takeover of McAfee, now known as Intel Security but today's release of the Intel SSD Pro 2500 Series changes that. This family of SSDs will work with McAfee ePolicy Orchestrator to allow the automatic implementation of hardware-based 256-bit encryption on these drives in a similar manner to what Endpoint Encryption has done in the past. Since it sits on the hardware Intel claims no impact to the speed is caused by the on the fly encryption. If you use Intel Setup and Configuration Software with vPro you can even monitor the health of deployed drives. Check out Intel's page here and the PR below.
SANTA CLARA, Calif., July 22, 2014 – Intel Corporation today announced an addition to the Intel® Solid-State Drive (SSD) Professional Family: the Intel® SSD Pro 2500 Series. This new business-class SSD delivers lower total cost of ownership, security and manageability features, and blazing-fast SSD performance demanded by today’s business users.
Intel SSD Pro 2500 Series offers IT departments peace of mind with advanced security features and capabilities designed for businesses ranging from small companies through large IT-managed enterprises. Security and remote manageability features, combined with lower annual failure rates than hard disk drives (HDDs), help to reduce the need for resource-intensive deskside visits.
Managing data security is critical for businesses and a challenge for IT leaders. Data breaches, often a result of lost or stolen PCs, can cost a business nearly $50,000 in lost productivity, replacement, data recovery and legal costs.1 To help businesses mitigate the threat of such costly breaches, the Intel Pro 2500 Series SSDs are self-encrypting drives (SED) utilizing hardware-based 256-bit encryption to protect data without a loss of performance. Additionally, the new Intel drives feature the Trusted Computing Group’s OPAL 2.0* standard and are Microsoft eDrive* capable. These policy-based controls help to prevent data breaches and support crypto erase to repurpose the drive for reuse.
“The need to protect assets, keep an eye on the bottom line and ensure employees have the best tools is a challenge for IT departments,” said Rob Crooke, Intel corporate vice president and general manager of the Non-Volatile Memory Solutions Group. “The Intel SSD Pro 2500 Series is a well-rounded solution to help balance those often competing needs. Adding the Pro 2500 Series to the Intel SSD Professional Family delivers a powerful storage solution to help businesses of all sizes meet their critical IT needs.”
“The Intel SSD Pro 2500 Series is the second-generation OPAL-based client storage solution that helps IT departments protect their users’ data and also provides valuable features to reduce operational costs,” stated Candace Worley, senior vice president and general manager, Endpoint Security, McAfee*, part of Intel Security. “The Pro 2500 Series is a perfect companion to our data protection solutions, managed by McAfee ePolicy Orchestrator*, all working in concert to provide IT departments with data security, management and control, wherever their endpoints may be.”
In an environment with Intel® vPro™ Technology, with Intel® Setup and Configuration Software and leading security software, the Pro 2500 Series drives can be managed remotely allowing IT to monitor and report drive health as well as track assets and remedy faults. This remote manageability enforces IT policies to help prevent mishaps and simultaneously provides a great user experience. Embedded and Internet of Things applications can also take advantage of the remote manageability features to help limit the number of IT professionals needed to oversee devices. To assist in protecting user data and lower the total cost of ownership, applications such as ATMs and remote digital signage can be updated, monitored and managed remotely.
“Corporations of every size are facing the growing challenge of protecting sensitive data and ensuring compliance with a litany of data protection laws and regulations,” said Bill Solms, president and CEO of Wave Systems*. “The Intel SSD Pro 2500 Series offers a sound foundation for any data security program, incorporating hardware-level encryption without impacting drive performance. Wave’s on-premise and cloud-based management software complements the Intel SSD Pro 2500 by offering remote drive provisioning, automated password recovery and secure audit logs to document that encryption was in place should a laptop become lost or stolen.”
The Intel SSD Professional Family is part of the Intel® Stable Image Platform Program, including a 15-month availability of the components and drivers for compatibility and stability across a qualified IT image. This helps minimize IT qualification and deployment times. The Intel SSD Pro 2500 Series also features five advance power modes helping to balance performance and power to enable a longer battery life and provide a better mobile experience.
The Intel SSD Pro 2500 Series will be available in both 2.5-inch and M.2 form factors and in capacities ranging from 120GB to 480GB. The Intel SSD Pro 2500 Series is backed by a 5-year limited warranty and features a world-class annualized failure rate (AFR) well below 1 percent. The AFRs of other SSDs and HDDs can reach as high as 5 percent or more in mobile environments.
Need 128GB at 450 MB/s in your pocket?
We don't normally do reviews on USB flash drives, even if they are USB 3.0 based. But the Corsair Flash Voyager GTX turned out to be a bit different. Not only is this a USB 3.0 capable thumb drive, it is powered by an SSD controller, pushing performance as high as 460 MB/s in our testing! Add to that capacity options of 128GB and 256GB and you have a flash drive that really stands out from majority of the market.
Check out the video review below that Allyn and I made about the Corsair Flash Voyager GTX 128GB flash drive and then continue on to see some more pictures and our quick benchmark results.
The Flash Voyager GTX is a bit large in pantheon of USB thumb drives but it's actually smaller than I expected it when I heard the capacity options available. You'll definitely be able to keep this around your neck or in your pocket without noticing it and you may still be able to keep it on your key ring.
What do you do with 128GB or 256GB of flash drive? Well, other than the obvious of having a huge capacity drive for your "sneaker net" implementation at your home or office, you can investigate more interesting usage models. If you are looking for a more secure place to store sensitive files that you don't want on your home or work PC full time, just keep them on the Flash Voyager GTX and plug it into a USB 3.0 port when you want access. You'll get performance on par with an SSD but the ability to quickly disconnect it.

As you saw in Al's review, the Samsung 850 drive is more than just a small bump in model number and performance, it is the stellar introduction to 3D NAND. The Tech Report is likely having nightmares from the drives reported longevity which is expected to be up to 10 times the cycles of current drives and means an update to their long running endurance test could see them testing into the 2020's. While they haven't yet added the 850 to that particular test they did post a review which starts out with a comprehensive look at the history of Flash technology and why 3D NAND is faster and more resilient than previous types; read on to get a better understanding of the fastest consumer SATA drive on the market.
"Most flash memory is limited to a single layer, but the V-NAND chips in Samsung's new 850 Pro SSD stack 32 layers on top of each other. This is next-level stuff, literally, and it's supposed to make the 850 Pro the fastest SATA drive around. We investigate."

Here are some goodies from yesterdays briefings at the 2014 Samsung SSD Summit:
Slides from the 3D V-NAND discussion. These provide some additional visuals for what I explained in the intro to the 850 PRO series SSD review:
Next we got into current launching lineups. First the 850 PRO that launched today:
Samsung also launched an 845DC PRO, which uses the previous generation 24-layer V-NAND:
Finally, as we walked out of the conference, we saw a 32-layer V-NAND wafer on display:
Taking die pictures is tricky...
...but persistence is rewarded:

Samsung has certainly been pushing the envelope in the SSD field. For the past two years straight, they have launched class leading storage products, frequently showing outside-the-box thinking. Their 840 PRO series was an impressive MLC performer to say the least, but even more impressive was the 840 EVO, which combined cost-efficient TLC flash with a super-fast SLC cache. The generous SLC area, present on each die and distributed amongst all flash chips within the drive, enabled the EVO to maintain PRO-level performance for the majority of typical consumer (and even power user) usage scenarios. The main win for the EVO was the fact that it could be produced at a much lower cost, and since its release, we've seen the EVO spearheading the push to lower cost SSDs.
All of these innovations might make you wonder what could possibly be next. Today I have that answer:
If you're going "Hey, they just changed the label from 840 to 850!", well, think again. This SSD might have the same MEX controller as its predecessor, but Samsung has done some significant overhauling of the flash memory itself. Allow me to demonstrate.
Here's standard (2D) flash memory, where the charge is stored on a horizontal plane:
..and now for 3D:
The charges (bits) are not stored at the top layer. They are stored within all of those smaller, thinner layers below it. You're still looking at a 2D plane (your display), so here's a better view:
Seeking asylum at some random baggage claim area?
Guess again. Here's a hint:
More to follow, boys and girls. Stay tuned!
Introduction, Specifications and Packaging
OCZ's RevoDrive series has been around for quite some time. We reviewed the first of the series over four years ago, and they just kept coming after that initial launch.
The full line of (now legacy) Revo / Z-Drive series products.
With the recent acquisition by Toshiba, it was only a matter of time before OCZ revamped the RevoDrive line with their new flash. It just makes sense, as Toshiba can be obtained much more readily (and cheaply) since they are now an in-house source for OCZ. With the Vector 150 and Vertex 460 already driving 19nm Toshiba flash, we now have the RevoDrive 350:
We suspected they might also count this as an update to the Revo line and not just a flash swap, so with a sample to test, let's see what's what!
