As you can see, UFS is not just for SD cards. These are going to be able to replace embedded memory in mobile devices, displacing the horror that is eMMC with something way faster. These devices are smaller than a penny, with a die size of just over 60 mm squared and boast a 32GB capacity.
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.
Also up is an overdue branding of Micron's XPoint (spoken 'cross-point') products:
More to follow from FMS 2016. A few little birdies told me there will be some good stuff presented this morning (PST), so keep an eye out, folks!
Press blast for Micron's UFS goodness appears after the break.

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.
Introduction, Specifications and Packaging
It's been too long since we took a look at enterprise SSDs here at PC Perspective, so it's high time we get back to it! The delay has stemmed from some low-level re-engineering of our test suite to unlock some really cool QoS and Latency Percentile possibilities involving PACED workloads. We've also done a lot of work to distill hundreds of hours of test results into fewer yet more meaningful charts. More on that as we get into the article. For now, let's focus on today's test subject:
Behold the Micron 9100 MAX Series. Inside that unassuming 2.5" U.2 enclosure sits 4TB of flash and over 4GB of DRAM. It's capable of 3 GB/s reads, 2 GB/s writes, and 750,000 IOPS. All from inside that little silver box! There's not a lot more to say here because nobody is going to read much past that 3/4 MILLION IOPS figure I just slipped, so I'll just get into the rest of the article now :).
The 9100's come in two flavors and form factors. The MAX series (1.2TB and 2.4TB in the above list) come with very high levels of performance and endurance, while the PRO series comes with lower overprovisioning, enabling higher capacity points for a given flash loadout (800GB, 1.6TB, 3.2TB). Those five different capacity / performance points are available in both PCIe (HHHL) and U.2 (2.5") form factors, making for 10 total available SKUs. All products are PCIe 3.0 x4, using NVMe as their protocol. They should all be bootable on systems capable of UEFI/NVMe BIOS enumeration.
Idle power consumption is a respectable 7W, while active consumption is selectable in 20W, 25W, and 'unlimited' increments. While >25W operation technically exceeds the PCIe specification for non-GPU devices, we know that the physical slot is capable of 75W for GPUs, so why can't SSDs have some more fun too! That said, even in unlimited mode, the 9100's should still stick relatively close to 25W and in our testing did not exceed 29W at any workload. Detailed power testing is coming to future enterprise articles, but for now, the extent will be what was measured and noted in this paragraph.
Our 9100 MAX samples came only in anti-static bags, so no fancy packaging to show here. Enterprise parts typically come in white/brown boxes with little flair.

Testing out twelve 9100 NVMe flash drives is not easy as it requires some interesting configurations to make the testing worth while, sticking them all in a box and running ATTO is not going to create valuable information. Those custom configurations revealed some interesting limitations, such as Windows' RAID having an upper limit of 385K IOPS and the Linux flavours tested topped out at 400K IOPS.
Server 2016 Technical Preview 5 turned out to be more stable than Server 2012 R2; somehow using Resource Monitor managed to crash hard enough to break the Server install in one case. 2016 also had that upper IOPS limit which was far below the drives actual capabilities. Drop by The Inquirer for look at the work which was done to set up for testing as well as the results.
"I have spent the past TWO months testing these cards, the past month of which has involved truly tormenting them. I've learned a lot of things. There's the basic "NVMe is faster" that you can get from reading about the theory behind the drives, but there have also been a lot of little practical tidbits that you only get to find out when you run face first into problems."

Introduction, Dynamic Write Acceleration, and Packaging
Micron joined Intel in announcing their joint venture production of IMFT 3D NAND just a bit over a year ago. The industry was naturally excited since IMFT has historically enabled relatively efficient production, ultimately resulting in reduced SSD prices over time. I suspect this time things will be no different as IMFT's 3D Flash has been aiming high die capacities since its inception, and I suspect their second generation will *double* per-die capacities while keeping speeds reasonable thanks to a quad-plane design implemented from the start of this endeavor. Of course, I'm getting ahead of myself a bit as there are no consumer products sporting this flash just yet - well not until today at least:
Marketed under Micron's consumer brand Crucial, the MX300 is their first entrant into the consumer space, as well as the first consumer SSD sporting IMFT 3D NAND. Crucial is known for their budget-minded SSDs, and for the MX300 they chose to go with the best cost/GB they could manage with what they had to work with. That meant putting this new 3D NAND into TLC mode. Now there are many TLC haters out there, but remember this is 3D NAND. Samsung's 850 EVO can exceed 500 MB/sec writes to TLC at its 500GB capacity point, and this MX300 is a product that is launching with *only* a 750GB capacity, so its TLC speed should be at least reasonable.
(the return of) Dynamic Write Acceleration
Dynamic Write Acceleration in action during a sequential fill - that last slowest part was my primary concern for the mX300.
TLC is not the only story here because Crucial has included their Dynamic Write Acceleration (DWA) technology into the MX300. This is a tech where the SSD controller is able to dynamically switch flash programming modes of the flash pool, doing so at the block level. This appears to be a feature unique to IMFT flash, as every other 'hybrid' SSD we have tested had a static SLC cache area. DWA's ability to switch flash modes on-the-fly has always fascinated me on paper, but I just haven't been impressed by Micron's previous attempts to implement it. The M600 was a bit all over the place on its write consistency, and that SSD was flipping blocks between SLC and MLC. With the MX300 flipping between SLC and *TLC*, there was a possibility of far more noticeable slow downs in the cases where large writes were taking place and the controller was caught trying to scavenge space in the background.

Tagged: micron, 3d nand, tlc, mlc, DEVSLP
Micron have unveiled their new line of 3D NAND, the SATA 6Gbps TLC 1100 and the NVMe MLC 2100, although they only shared details of the former. The 1100 will introduce DEVSLP mode, where the drives power draw will dip to less than 2mW on the smaller drives, 4mW for the 1TB with the 2TB model requiring 25mW. The TLC used in the drive is rather impressive, the advertised speeds come very close to what their MLC based M600 drives are capable of. Check out the full specs and more over at The Register.
"Intel, its flash foundry partner, introduced its own 3D SSDs, MLC (2bits/cell) ones, in March with the DC P3320 and P3520, with maximum capacity of 2TB. These had an NVME interface whereas Micron’s 1100 has the slower 6Gbit/s SATA interface."

Tagged: Ryan's Law, NVMe, micron
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.
"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."

There has been a lot of recent shuffling about in the world of enterprise storage. I’m writing up this post from a Micron product launch event in Austin, Texas. Today they are launching a round of enterprise SSD products. These lines cover the full storage gamut from M.2 to U.2 to HHHL. While prior Micron SSDs were bottlenecked by AHCI and PCIe 2.0, these new lines are using Marvell controllers and are capable of PCIe 3.0 x4 speeds (plus NVMe).
The workhorse of the lineup is the 9100, which will be available in HHHL and U.2 2.5” 15mm form factors.
Micron is not the only company pushing further into this space. Less than two weeks ago, Intel ran their ‘Cloud Day’ event, where they launched a new Xeon CPU and a plethora of new SSDs, some of which were based on IMFT 3D NAND tech (SSD DC P3320). Intel also launched the client 540s and business 5400s product lines, which are based on Silicon Motion SM2256 controllers driving SK Hynix hybrid (SLC+TLC) flash. While these controllers and flash are coming from external sources, they must still pass Intel’s rigorous qualification and compatibility validation testing, so failure rates should be kept to a minimum.
Another aspect of this Micron launch day is their push into the production of not only SSDs, but all-flash storage devices. Dubbed ‘Micron Accelerated Solutions’, these are devices built, serviced, and supported by Micron. They naturally contain Micron SSDs, but also draw on other vendors like Supermicro and Nexenta. The products range from VMware SANs, to Ceph solutions capable of 1 million IOPS and 140 Gbps, to software-defined storage. I’ll be sitting through briefings and asking questions about these products when this post is set to go live, and I will update this space with any additional juicy tidbits once we wrap up for the day.
Apparently we are going to see consumer IMFT 3D TLC NAND *this month* in the form of a Crucial MX300!
...and in a couple of months we will see Crucial M.2 PCIe SSDs:
There was also some discussion on XPoint (spoken 'cross point') and where Micron sees this new storage being implemented. Expected to see scaled production in 2017 and 2018, XPoint is non-volatile (like flash) but extremely fast (like DRAM). There was not much said beyond generalities, but they did have a wafer, and you know I love die shots:
I was not permitted to get a better die shot of the wafer at this event, as the Micron rep specifically requested that journalists only use photos that were shot from stage distance. Fortunately, this was not the only event where I have photographed a XPoint wafer. Here is a photo I caught at a prior event:
Here is a quick breakdown of the products launched by both Intel and Micron over the last two weeks:
- SSD DC P3520 and P3320
- First SSDs to use 256Gbit/die 32-layer IMFT 3D NAND.
- PCIe 3.0 x4 HHHL and 2.5” U.2
- SSD DC D3700 and D3600
- PCIe 3.0 x4 2.5” U.2 dual-port design.
- Dual-port means two hosts can access a single SSD through the use of a special backplane that merges the PCIe lanes from two separate systems into a single U.2 connector. This is a move for increased redundancy, as one system can fail and the same flash storage will still be available to the failover system.
- PCIe 3.0 x4 2.5” U.2 dual-port design.
- SSD DC S3100
- SATA 2.5” SLC+TLC hybrid for enterprise
- Intended for boot OS / caching / index storage duties
- SATA 2.5” SLC+TLC hybrid for enterprise
- SSD 540s and Pro 5400s
- Silicon Motion SM2256 + SK Hynix SLC+TLC hybrid flash
- Pro 5200s adds Intel vPro / OPAL 2.0 and Microsoft eDrive support
- SSD E 5400s and E 5410s
- Silicon Motion SM2256 + SK Hynix flash
- Small capacity M.2 2280 and 2.5” SATA
- 9100 PCIe SSD
- PCIe 3.0 x4 HHHL and 2.5” U.2 15mm
- Up to 3.2TB capacity
- 7100 PCIe SSD
- PCIe 3.0 x4 M.2 22110 and 2.5” U.2 7mm
- SAS 2.5”
- Micron Accelerated Solutions
That’s a whole lot of flash related product launches in a very short period of time. I’m excited to see large pushes into the enterprise because that means we will see this tech trickle down to consumers and power users that much sooner!
The Micron NVMe press release was a bit light on details, so I’ve included their Accelerated Solutions release after the break.

Here's a brief post for our Canadian fans. If you have been interested in a decent, large SSD, then you might want to check out Newegg Canada. The Mushkin Enhanced Reactor 1TB is currently $100 off, which puts it at a price of $299.99 CDN plus tax and shipping. While 30c/GB might sound mundane to our neighbours to the south, the currency conversion works out to about 23c/GB USD.
Sure, it's not the fastest SSD on the market, but it's a solid, mainstream one. A 2TB version also exists, but you will be paying about $60 more than just getting two, 1TB SKUs. This version uses the Silicon Motion SM2246EN controller and Micron flash. We might end up with better or cheaper drives coming in the future, I have no idea, but this should be good for cheap, decent, and now.
