If you are an enterprise, SanDisk is getting a bit SAS-y with some pretty large SSDs. How large? 4TB. Not large enough? Why are you the way you are. Also, according to VR-Zone, 6TB and 8TB versions will follow, in 2015 (Update: 5/6/2014 @ 5:56pm EST -- VR-Zone might have meant "16TB"... as Tom's IT Pro claims to have heard from SanDisk). These drives will be produced with 19nm NAND, not utilizing the 15nm cells from their partnership with Toshiba. SanDisk claims their choice of 19nm was for reliability. Also, clearly, they are not suffering with density.
Speaking of reliability, the SanDisk warranty is rated in both time as well as the supported number of full drive writes per day. The Optimus MAX SSD is rated at one-to-three drive writes per day, or 4-12TB per day, over the course of its 5-year warranty.
4TB Optimus MAX SSDs are expected to launch "to select OEMs and through the channel" in Q3.
VisionTek recently released a new storage product dubbed the mSATA mini USB 3.0 Bus-Powered SSD Enclosure (900696). Despite the name, VisionTek has an interesting product on its hands as it not only enables speedy portable storage (assuming you have hardware with USB 3.0 ports of course), but allows users to put any mSATA SSDs that would otherwise be gathering dust in a drawer to good use! Essentially, it is a small metal enclosure that accepts a mSATA SSD and interfaces it with a PC over USB 3.0.
The mSATA USB 3.0 enclosure measures 2.88" x 1.63" x 0.51" and is constructed of aluminum with a textured titanium color (for aesthetics) and rounded edges. Users can install any mSATA SSD up to 50mm in length. A third generation ASMedia ASM1153E controller then performs the conversion from the drive's SATA I, II, or III interface to USB 3.0. Naturally, you are going to take a performance hit due to the added latency and interface conversion introduced by the ASMedia controller versus directly attaching the drive to a motherboard's mSATA slot. Fortunately, the hit to performance is fairly minimal when dealing with large file transfers and sequential read and write performance.
According to Legit Reviews, their Kingston 120GB (SATA 3 6 Gbps) mSATA solid state drive saw sequential read and write speeds of 271 MB/s and 160 MB/s respectively when connected to a motherboard slot. When installed in the USB 3.0 enclosure, speeds dropped to 250 MB/s sequential reads and 158 MB/s sequential writes. Further, a large 71GB 4K video file transfer averaged out to 151 MB/s. The exact speeds will vary with the specific drive users install, but the thing to note is that the performance hit should be minimal (at least the performance relating to dealing with file copies, random access will take a larger hit) despite adding the USB 3.0 interface to the equation.
The VisionTek drive is available now with a three year warranty for $30.72 from Amazon, which is a tempting price for fast portable storage especially if you already have a mSATA drive laying around! Notably, it seems that VisionTek is not the only manufacturer sourcing these boards, as MyDigitalSSD has a simlar drive with an MSRP of $24.99.
If you are interested in putting together your own SSD-powered portable drive, check out the full review linked above.
Now, if I can only encourage Allyn to recycle some of his mSATA drives...

KitGuru had a chance to test the ASUS Z97-Deluxe with a Concept Edition SATA Express SSD from ASUS to see what happens when you can feed the data from an SSD across two SATA ports, giving it the bandwidth of two PCIe lanes. That should allow a theoretical 10Gbps bandwidth as PCIe 3.0 lanes are still being held in reserve as there are not that many available on an LGA1150 board but as KitGuru points out "leaked information suggest (we still cannot confirm anything) that M.2 support will be native to the ‘future Intel chipset’." Check out their review and be prepared to be amazed that the speed of 728MBps was lower than expected.
"We revisit the SATA Express interface to obtain a more up-to-date look at what the next generation of SATA connections is capable of. Our tools for the job; a retail Asus motherboard set to release soon, and a concept version of Asus’ Hyper Express enclosure, internally powered by solid state storage."

Samsung has been working with TLC flash for a while now, both the original 840 and the 840 EVO utilize that type of flash, the increased yields offer lower pricing at the cost of a reduced number of writes before the flash begins to fail. The Register has posted their announcement of a new product line aimed at the data centre; the PM835T family will come in 240GB, 480GB and 960GB models and will also use TLC flash, with pricing predicted to be comparable to consumer level drives. With Samsung's 10nm-class TLC flash the experts at SMART suspect a 500 phase/erase cycle lifetime however depending on how Samsung has designed the drives the actual number could be much higher, they do offer a 3 year warranty on their current TLC drives. For now Samsung is not releasing an official expected lifetime for these drives which raises a question, will enterprise feel the short term cost savings are worth the long term replacement costs?
"Triple-level cell (TLC) flash chips mean fabs can extract more flash capacity from a silicon wafer, and so production costs are lower than for two-level cell MLC technology. Samsung says it gets "a 30 per cent increase in manufacturing efficiency compared to SSDs that use 2-bit NAND flash components."

Tagged: toshiba, ssd, 15nm
While we often see smaller fabrication nodes discussed in terms of faster and more power efficient processors, it also increases storage density for memory circuits. In fact, it is probably easier to visualize how a process shrink will increase memory capacity than it is to ponder the benefits for CPUs and GPUs. Smaller features in the same area gives more places to cram data. Toshiba is starting to mass produce 15nm NAND Flash at Fab 5 in Yokkaichi.
While not mentioned in the press release, I believe that SanDisk and Toshiba are still in a partnership. The facility being discussed was actually a $4 Billion USD joint-venture between these two companies. I, reasonably, expect that SanDisk will also see some benefits from today's announcement. According to the press release, 15nm MLC is already in mass production with TLC following in June.
I brought up this story to Allyn, to see if he had any insights on it. He noted that 15nm is getting quite small. I asked about its implications in terms of write longevity, as that is has been the biggest concern in previous node shrinks. He guesses that the flash should be able to handle around 1,000 writes on average, compared to ~3,000 writes on IMFT's 20nm process. Keep in mind, IMFT prides itself on enterprise longevity and so, at least to me, it sounds fairly reasonable. Toshiba also mentions that they will have products for the high reliability market, such as enterprise SSDs.
The announcement does not mention anything that you can go out and buy yet, though. At the moment, it is behind-the-scenes stuff. It should be soon. I doubt that Toshiba would mass produce components like this without products or OEMs lined up.

Sticking with ADATA today, The Tech Report has also put together a review of the Premiere Pro SP920 which was eerily familiar to them. The Marvell controller, Micron MLC NAND and DRAM cache all mirrored the Crucial M550 which they reviewed last month. One difference they noted right off the start was support for third party utilities to read the SMART data, with which they had far more success than with Crucial's drive. Their performance results were not surprising; the two drives performed the same which leaves price and support as the determining factor when purchasing one of these two twins, something that The Tech Report offers advice on in their conclusion.
"Adata's latest Premiere Pro SP920 SSD bears an uncanny resemblance to a big-name drive that was released recently. This isn't a straight copycat, though. Read on to see what makes the SP920 different."

Introduction, Specifications and Packaging
ADATA has been in the storage market for a good while now. I like to think of them as the patient underdog. They don't necessarily come out with the shiny new controller or flash technology. Instead they tend to sit back and wait for a given set of hardware to mature and drop in price a bit. Once that happens, they figure out how to package the matured technology into a device of relatively low cost as compared to the competition. They have done so again today, with their new Premier Pro SP920 lineup:
As hinted at earlier, this line does not use the newest Marvell controller, but as Marvell controllers have been very capable SATA 6Gb/sec units for a long time now, that is not necessarily a bad thing. In addition, Marvell controllers have a track record of gaining significant performance margins as their firmware matures, which makes ADATA's later entrance more of a good thing.
Introduction and Background
Back in 2010, Intel threw a bit of a press thing for a short list of analysts and reviewers out at their IMFT flash memory plant at Lehi, Utah. The theme and message of that event was to announce 25nm flash entering mass production. A few years have passed, and 25nm flash is fairly ubiquitous, with 20nm rapidly gaining as IMFT scales production even higher with the smaller process. Last week, Intel threw a similar event, but instead of showing off a die shrink or even announcing a new enthusiast SSD, they chose to take a step back and brief us on the various design, engineering, and validation testing of their flash storage product lines.
At the Lehi event, I did my best to make off with a 25nm wafer.
Many topics were covered at this new event at the Intel campus at Folsom, CA, and over the coming weeks we will be filling you in on many of them as we take the necessary time to digest the fire hose of intel (pun intended) that we received. Today I'm going to lay out one of the more impressive things I saw at the briefings, and that is the process Intel goes through to ensure their products are among the most solid and reliable in the industry.

Back in January I wrote a short editorial that asked the question: "Is now the time to buy an SSD?" At that time we were looking at a combination of price drops with a lack of upcoming hardware releases. Since that published we have seen the release of the Intel 730 Series SSDs and even the new Crucial M550. While those are interesting drives to be sure (review pending on the M550), they aren't changing our opinions on the currently available, and incredibly cheap, solid state options.
While looking for some new hardware for the office, I found that the 1TB Samsung 840 EVO is now at an all time low $469! That is one of the faster SSDs on the market, and one of Allyn's favorites, for $0.469/GB!! I have included an updated table below with some of the most popular SSDs and their prices.
|Samsung 840 EVO||120 GB||$0.69/GB||$83 - Amazon|
|250 GB||$0.55/GB||$139 - Amazon|
|500 GB||$0.51/GB||$259 - Amazon|
|750 GB||$0.51/GB||$388 - Amazon|
|1000 GB||$0.46/GB||$469 - Amazon|
|Samsung 840 Pro||128 GB||$0.92/GB||$119 - Amazon|
|256 GB||$0.77/GB||$199 - Amazon|
|512 GB||$0.74/GB||$413 - Amazon|
|Intel 530 Series||120 GB||$0.91/GB||$89 - Amazon|
|180 GB||$0.80/GB||$144 - Amazon|
|240 GB||$0.62/GB||$149 - Amazon|
|480 GB||$0.87/GB||$419 - Amazon|
|Crucial M500 Series||120 GB||$0.57/GB||$69 - Amazon|
|240 GB||$0.49/GB||$119 - Amazon|
|480 GB||$0.47/GB||$229 - Amazon|
|960 GB||$0.45/GB||$439 - Amazon|
The biggest price drops were seen in the higher capacity drives including, the Samsung 840 EVO 1TB and 750GB models, the Intel 530 Series 480GB drive and even the Crucial M500 960GB and 480GB drives. Numerically the best value is with the 960GB Crucial M500 drive at $0.45/GB but it is followed very closely by that 1TB Samsung 840 EVO.
As of now, the Intel 730 Series of SSDs is available for sale on Amazon.com but their price per GB comparisons don't really match that of the EVO or M500. They are great drives, just read Allyn's review to see the proof of that, but they are targeted at the very performance conscious. The Crucial M550 is brand new, and looks interesting; expect us to dive more into that line very soon.
For me personally, grabbing a 750GB SSD is incredibly enticing and I think I'll find a handful in my cart to update our older 180GB SSD test beds.
