Before even looking at the performance the real selling point of the new OCZ ARC 100 is the MSRP, the 240GB and 480GB models are slated to be released at $0.50/GB and will likely follow the usual trend of SSD prices and drop from there. The drives use the Barefoot 3 controller, this one clocked slightly lower than the Vertex 460 but still capable of accelerating encryption. Once The Tech Report set the drive up in their test bed the performance was almost on par with the Vertex 460 and other mid to high end SSDs, especially in comparison to the Crucial MX100.
"OCZ's latest value SSD is priced at just $0.50 per gig, but it hangs with mid-range and even high-end drives in real-world and demanding workloads. It's also backed by an upgraded warranty and some impressive internal reliability data provided by OCZ. We take a closer look:"

Introduction, Specifications and Packaging
OCZ is on what I would consider to be an upswing now that it exists under the relative safety of its parent company, Toshiba. Shortly after they were acquired, OCZ cut a bunch of unnecessary and/or redundant SKUs from their inventory and simultaneously began the transition of all of their product lines to exclusively use Toshiba branded flash. It only makes sense, given that flash is now available in-house - a luxury OCZ had wanted to have for quite some time. The changeover so far has refreshed the Vector 150, Vertex 460, and most recently the RevoDrive 350. Today OCZ has made another change, but instead of refreshing an old product, they are introducing a new one:
Behold the ARC 100!
To those wondering why OCZ needs another model SSD, and where that model will fall in their lineup, here's everything you need to see:
...so we have a slightly de-rated SSD, with the same Indilinx Barefoot controller, and the same Toshiba 19nm flash, but with a *significantly* reduced price. I wouldn't sweat the 20GB/day rating, as the vast majority of users will average far less than that daily when that usage is spread over a multi-year period. Even heavy gamers that blow through 100+GB of writes on an initial system and game install will still average far less than that over the subsequent months and years. Here is a look at the complete OCZ product spectrum, including their business and PCIe offerings:
OK, so they've got my attention with this price thing, so lets see how well the ARC performs given its lower cost:

HGST has refreshed their 12Gbit/s SAS series of Ultrastar SSDs with denser 20nm which has upped the read speeds though the writes do suffer somewhat. As they are enterprise drives they have rather impressive lifespans, the 800GB is rated at 25 full drives writes/day for the length of the 5 year warranty. They also offer encryption and erasure tools that are superior to enthusiast drives, along with a much higher price tag. The Register also offers information on the new Ultrastar HDDs and a link to the spec sheets but as of yet we do not have any benchmarks.
"HGST has refreshed its Ultrastar enterprise SSD line, using denser 20nm NAND to replace the previous 25nm flash, doubling capacity, upping read performance but lowering write performance a tad in the process."

Silicon Motion has announced their SM2256 controller. We caught a glimpse of this new controller on the Flash Memory Summit show floor:
The big deal here is the fact that this controller is a complete drop-in solution that can drive multiple different types of flash, as seen below:
The SM2256 can drive all variants of TLC flash.
The controller itself looks to have decent specs, considering it is meant to drive 1xnm TLC flash. Just under 100k random 4k IOPS. Writes are understandably below the max saturation of SATA 6Gb/sec at 400MB/sec (writing to TLC is tricky!). There is also mention of Silicon Motion's NANDXtend Technology, which claims to add some extra ECC and DSP tech towards the end of increasing the ability to correct for bit errors in the flash (more likely as you venture into 8 bit per cell territory).

At the Flash Memory Summit, Phison has updated their SSD controller lineup with a new quad-core SSD controller.
The PS3110 is capable of handling TLC as well as MLC flash, and the added horsepower lets it push as high as 100k IOPS.
Also seen was an upcoming PS5007 controller, capable of pushing PCIe 3.0 x4 SSDs at 300k IOPS and close to 3GB/sec sequential throughputs. While there were no actual devices on display of this new controller, we did spot the full specs:
Full press blast on the PS3110 appears after the break:

Tagged: ssd, phase change memory, PCM, hgst, FMS 2014, FMS
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.

Tagged: FMS, vnand, tlc, ssd, Samsung, FMS 2014, Flash Memory Summit
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!
The Thecus N2560 is a dual-bay NAS Server powered by an Intel Atom SoC. With the addition of HDMI output could this be the answer for some basic HTPC needs as well?
The Thecus N2560 at work in the living room
The N2560 is similar in some ways to the Thecus N2310 NAS we looked at a couple of months ago, but it builds on both the functionality and power of that unit. Both are 2-bay designs with support for up to 8TB of storage via dual 4TB hard drives, and they run the same OS (ThecusOS 6). There are some very big differences, too. The N2560 boasts an Intel Atom SoC which provides dual 1.60 GHz cores, compared to the N2310’s single 800 MHz PowerPC core. The N2560 also features a full-size HDMI output as well as SPDIF digital audio output, making it a potential alternative for some HTPC tasks.
The Thecus N2560 is an attractive-looking device, with the smooth lines and finish of a more expensive product. But beyond the N2560's appearance and basic function as a NAS, this is really a server. Digital audio and video output is certainly an impressive addition for a device that retails for around $180, making it a compelling budget HTPC option if the OS and media software work well. Since the basics of the Thecus OS and NAS usage were covered with the N2310, the media output potential of the N2560 is the area of focus for this review.

You might remember Allyn say that Samsung's 850 Pro is the closest to total saturation of SATA 6Gbps. The other option that we have seen is the bunch of SSDs that are attached to a PCI Express bus. HGST, formerly Hitachi Global Storage Technologies, has just SAS'd back (that was a terrible pun... which I refuse to apologize for) with a Serial Attached SCSI 12 Gbps model (pdf link). They claim a maximum read throughput of 1100 MB/s, with 64K chunks, and 130,000 IOPS, with 4K random accesses.
The drives will be based on Intel 20nm enterprise-grade NAND with two bits per memory cell (MLC). Its durability is rated at 25 full driver writes per day for 5 years. Models will range from 100GB, all the way up to 1600GB (1.6TB).
While I am limited to Google Translate, there does not appear to be any price or availability information provided. They are enterprise drives, however, so I expect it to be above typical consumer drives.
