We covered some other Storage Visions sightings in a prior post, so now that a bit of the CES dust is settling down, here's the rest of what was cool to see at Storage Visions:

We'll start off with the Sonnet Tempo SSD Pro Plus, seen here with a pair of OWC Mercury Extreme Pro SSDs installed. This is a PCIe to 4-channel SATA HBA. The controller does not appear to employ RAID, leaving that functionality up to the host system OS. Two 2.5" SATA devices can be mounted directly to the PCB, and an additional two SATA channels are available through the rear panel eSATA ports. This card is marketed primarily as a storage expander for Mac products, and can be connected to a Mac Pro via a Thunderbolt-to-PCIe card expander.

Here is an ASUS Copper, which bridges M.2 (enclosed within a 2.5" housing) to a SATA Express link. This may be handy for current generation PCIe 2.0 x2 M2 devices, but with PCIe 2.0 x4 and 3.0 x4 SSDs on the horizon, a SATA Express device of this type will rather quickly become a throughput bottleneck.

Various recent enterprise SSDs. Bottom left is our first sighting of a P3500, sitting next to a Micron P420M, which is just below a Micron M500DC. The right side is all Samsung, and includes an XS1715, which is not SATA, but PCIe/NVMe via an SFF-8639 connector. There are a few M.2 units in the center, and what appears to be another 1715 HHHL unit (PCIe/NVMe) at the bottom right.

That wraps up the Storage Visions goodies. Stand by for more storage related posts as we comb through all of the press releases and photos from the meetings we attended earlier this week.

Another look at Micron's M600 series; the SSD that swings both ways

The Tech Report took a different look at Micron's M600 SSD than Al did in his review.  Their benchmarks were focused more on a performance comparison versus the rest of the market, with over two dozen SSDs listed in their charts.  As you would expect the 1TB model outperformed the 256GB model but it was interesting to note that the 256GB MX100 outperformed the newer M600 in many tests.  In the final tally the new caching technology helped the 256GB model perform quite well but it was the 1TB model, which supposedly lacks that technology proved to be one of the fastest they have tested.

"Micron's new M600 SSD has a dynamic write cache that can treat any block on the drive as high-speed SLC NAND. This unique feature is designed to help lower-capacity SSDs keep up with larger drives that have more NAND-level parallelism, and we've tested the 256GB and 1TB versions to see how well it works."

Introduction and Specifications

Today Micron lifted the review embargo on their new M600 SSD lineup. We covered their press launch a couple of weeks ago, but as a recap, the headline new feature is the new Dynamic Write Acceleration feature. As this is a new (and untested) feature that completely changes the way an SSD must be tested, we will be diving deep on this one later in this article. For the moment, let's dispose with the formalities.

Here are the samples we received for testing:

DSC05770.JPG

It's worth noting that since all M600 models use 16nm 128Gbit dies, packaging is expected to have a negligible impact on performance. This means the 256GB MSATA sample should perform equally to its 2.5" SATA counterpart. The same goes for comparisons against M.2 form factor units. More detail is present in the specs below:

Specifications:

M600-4.png

Highlights from the above specs are the increased write speeds (no doubt thanks to Dynamic Write Acceleration) and improved endurance figures. For reference, the prior gen Micron models were rated at 72TB (mostly regardless of capacity), so seeing figures upwards of 400TB indicates Micron's confidence in their 16nm process.

Packaging:

Sorry to disappoint here, but the M600 is an OEM targeted drive, meaning its 'packaging' will likely be the computer it comes installed in. If you manage to find it through a reseller, it will likely come in OEM-style brown/white box packaging.

We have been evaluating these samples for just under a week and have logged *many* hours on them, so let's get to it!

Micron's M600 SSD, SLC in the front MLC in the back

Subject: Storage | September 18, 2014 - 07:10 PM |
Tagged: micron, M600, SLC. MLC, DWA

Micron's M600 SSD has a new trick up its sleeve, called dynamic write acceleration which is somewhat similar to the HDDs with an NAND cache to accelerate the speed frequently accessed data can be read but with a brand new trick.  In this case SLC NAND acts as the cache for MLC NAND but it does so dynamically, the NAND can switch from SLC to MLC and back depending on the amount of usage.  There is a cost, the SLC storage capacity is 50% lower than MLC so the larger the cache the lower the total amount of storage is available.  As well the endurance rating is also higher than previous drives, not because of better NAND but because of new trim techniques being used.  This is not yet a retail product so The Tech Report does not have benchmarks but this goes to show you there are plenty more tricks we can teach SSDs.

"Micron's new M600 SSD can flip its NAND cells between SLC and MLC modes on the fly, enabling a dynamic write cache that scales with the drive's unused capacity. We've outlined how this dynamic write acceleration is supposed to impact performance, power consumption, and endurance."

Micron launches M600 SATA SSD with innovative SLC/MLC Dynamic Write Acceleration

Subject: Storage, Shows and Expos | September 16, 2014 - 02:29 PM |
Tagged: ssd, slc, sata, mlc, micron, M600, crucial

You may already be familiar with the Micron Crucial M550 line of SSDs (if not, familiarize yourself with our full capacity roundup here). Today Micron is pushing their tech further by releasing a new M600 line. The M600's are the first full lineup from Micron to use their 16nm flash (previously only in their MX100 line). Aside from the die shrink, Micron has addressed the glaring issue we noted in our M550 review - that issue being the sharp falloff in write speeds in lower capacities of that line. Their solution is rather innovative, to say the least.

Recall the Samsung 840 EVO's 'TurboWrite' cache, which gave that drive a burst of write speed during short sustained write periods. The 840 EVO accomplished this by each TLC die having a small SLC section of flash memory. All data written passed through this cache, and once full (a few GB, varying with drive capacity), write speed slowed to TLC levels until the host system stopped writing for long enough for the SSD to flush the cached data from SLC to TLC.

high_res_M600D_form_factors_1.jpg

The Micron M600 SSD in 2.5" SATA, MSATA, and M.2 form factors.

Micron flips the 'typical' concept of caching methods on its head. It does employ two different types of flash writing (SLC and MLC), but the first big difference is that the SLC is not really cache at all - not in the traditional sense, at least. The M600 controller, coupled with some changes made to Micron's 16nm flash, is able to dynamically change the mode of each flash memory die *on the fly*. For example, the M600 can place most of the individual 16GB (MLC) dies into SLC mode when the SSD is empty. This halves the capacity of each die, but with the added benefit of much faster and more power efficient writes. This means the M600 would really perform more like an SLC-only SSD so long as it was kept less than half full.

M600-1.png

As you fill the SSD towards (and beyond) half capacity, the controller incrementally clears the SLC-written data, moving that data onto dies configured to MLC mode. Once empty, the SLC die is switched over to MLC mode, effectively clearing more flash area for the increasing amount of user data to be stored on the SSD. This process repeats over time as the drive is filled, meaning you will see less SLC area available for accelerated writing (see chart above). Writing to the SLC area is also advantageous in mobile devices, as those writes not only occur more quickly, they consume less power in the process:

M600-2.png

For those worst case / power user scenarios, here is a graph of what a sustained sequential write to the entire drive area would look like:

M600-3.png

Realize this is not typical usage, but if it happened, you would see SLC speeds for the first ~45% of the drive, followed by MLC speeds for another 10%. After the 65% point, the drive is forced to initiate the process of clearing SLC and flipping dies over to MLC, doing so while the host write is still in progress, and therefore resulting in the relatively slow write speed (~50 MB/sec) seen above. Realize that in normal use (i.e. not filling the entire drive at full speed in one go), garbage collection would be able to rearrange data in the background during idle time, meaning write speeds should be near full SLC speed for the majority of the time. Even with the SSD nearly full, there should be at least a few GB of SLC-mode flash available for short bursts of SLC speed writes.

This caching has enabled some increased specs over the prior generation models:

M600-4.png

M600-5.png

Note the differences in write speeds, particularly in the lower capacity models. The 128GB M550 was limited to 190MB/sec, while the M600 can write at 400MB/sec in SLC mode (which is where it should sit most of the time).

We'll be testing the M600 shortly and will come back with a full evaluation of the SSD as a whole and more specifically how it handles this new tech under real usage scenarios.

Full press blast after the break.

Crucial Launching MX100 Mainstream SSD Series in June

Subject: Storage | May 22, 2014 - 12:23 PM |
Tagged: micron, crucial, mx100, ssd

You probably saw some news floating around yesterday that leaked out about an upcoming Crucial MX100 SSD using 16nm flash with an eye towards the mainstream price segment. While we are waiting for our samples of these units to arrive, we did get this comment from Crucial on the matter.

The word is out that Crucial will be launching a new SSD in the early June 2014 timeframe called the Crucial MX100 SSD. The new MX100 will be a competitively-priced, 2.5" SSD based on Micron’s new 16nm chips, and will be the successor to the Crucial M500 drive. The high-performance Crucial M550 drive will also remain part of the Crucial SSD product line-up.

We’re excited to share that PC Perspective has been fully briefed on the new Crucial MX100 by the Crucial SSD product marketing team and have a review sample in hand that we’re now rigorously testing. Once the MX100 drive is officially announced, we’ll have a complete product overview and benchmarks to share with you directly. Stay tuned for the full scoop here!

If you bought RAM between 1998 and 2002 from Samsung, Micron, Hynix, Infineon, NEC, and Toshiba in the USA, you are entitled to a small payout, assuming you have proof of purchase.  The DRAM makers never admitted guilt and chose to settle out of court and you have until August 1st to follow the link in The Inquirer's story to put in a claim.  If you wish to opt out and sue them yourself you have until May 5th to do so but you might be better off taking the $10.

CES 2014: Micron makes further advances in DDR4 memory

Subject: Storage, Shows and Expos | January 8, 2014 - 12:57 AM |
Tagged: ram, micron, memory, ddr4, CES 2014, CES

While the Crucial did not have much in the way of new flash memory product launches this year, Micron as a whole has been busily churning out further revisions of DDR4 memory. While our visit last year only revealed a single prototype for us to look at, now we have all of the typical form factors covered:

2014-01-07 13-36-20.JPG

From top down we have enterprise, enthusiast, OEM, and SO-DIMM form factors, all populated with DDR4 parts. All that needs to happen now is for motherboard and portable manufacturers to get on board with the new technology. As with all chicken-and-egg launches, someone needs to take the first plunge, and here we can see Micron has certainly been on the leading edge of things. That enterprise part above is a full 16GB (not bits!) of DDR4 capacity.

That RAM is stacked

Subject: General Tech | November 28, 2013 - 01:48 PM |
Tagged: DRAM, HMC, hybrid memory cubes, micron, TSV

Hybrid Memory Cubes are DRAM stacked in layers with logic on the bottom layer to decide which memory layer to address commands to whic is being developed by a team that includes Altera, ARM, IBM, SK Hynix, Micron, Open-Silicon, Samsung and Xilinix.  This is intended to give DRAM enhanced parallelization which will help it keep up with today's multi-cored processors.  Micron's example which the Register takes a look at here claims up to 10 GB/sec (80 Gb/sec) of bandwidth from each of the 16 vaults present on the chip, a vault being an area of memory on a layer.  That compares favourably to the maximum theoretical JEDEC speed of DDR3-1333 which is just a hair over 10GB/s.  Read more here.

hmc_1.jpg

"Dratted multi-core CPUs. DRAM is running into a bandwidth problem. More powerful CPUs has meant that more cores are trying to access a server’s memory and the bandwidth is running out.

One solution is to stack DRAM in layers above a logic base layer and increase access speed to the resulting hybrid memory cubes (HMC), and Micron has done just that."
