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:
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:
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.
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 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."

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.
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.
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:
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:
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:
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.
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!

As a replacement for the Crucial M500 line, we expect the MX100 to be a big seller. Just look at the M500 price on Amazon.com today: 960GB for $459 or 480 GB for $219! That's really all we know for now, check back for Allyn's testing very soon!

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.
"Remember getting hosed on those 128MB DIMM RAM sticks back in Y2K? Well, it's time to exact your revenge: with a $10 payout."

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:
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.

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.
"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."

Along with the release of new mobile workstations, Dell announced three new desktop workstations. Specifically, Dell is launching the T3610, T5610, and T7610 PC workstations under its Precision series. The new systems reside in redesigned cases with improved cable management, removable power supplies (tool-less, removable by sliding out from rear panel), and in the case of the T7610 removable hard drives. All of the new Precision workstations have been outfitted with Intel's latest Ivy Bridge-EP based Xeon processors, ECC memory, workstation-class graphics cards from AMD and NVIDIA, Xeon Phi accelerator card options, LSI hardware RAID controllers, and updated software solutions from Intel and Dell.
The new Precision workstations side-by-side. From left to right: T3610, T5610, and T7610.
Dell's Precision T3610 is a the mid-tower system of the group powered by single socket Xeon E5-2600 v2 hardware that further supports up to 128GB DDR3 ECC memory, two graphics cards, three 3.5” hard drives, and four 2.5” SSDs.
The Precision T3610, a new single socket, mid-range workstation.
The Precision T5610 ups the ante to a dual socket IVB-EP processor system that can be configured with up to 128GB DDR3 ECC memory, two AMD FirePro or NVIDIA Quadro (e.g. Quadro K5000) graphics cards, a Tesla K20C accelerator card, three 3.5” hard drives, and four 2.5” solid state drives.
Finally, the T7610 workstation supports dual Intel Ivy Bridge-EP Xeon E5-2600 v2 series processors (up to 24 cores per system), up to 512GB DDR3 ECC memory, three graphics cards (including two NVIDIA Quadro K6000 cards), four 3.5” hard drives, and eight 2.5” SSDs.
Dell's Precision T5610 dual socket workstation.
The new Precision workstations can also be configured with an Intel Xeon Phi 3120A accelerator card in lieu of a Tesla card. The choice will mainly depend on the applications being used and the development resources and expertise available. Both options are designed to accelerate highly parallel workloads in applications that have been compiled to support them. Further, users can add an LSI hardware RAID card with 1GB of onboard memory to the systems. Dell further offers a Micron P320h PCI-E SSD that, while not bootable, offers up 350GB of high performance storage that excels at high sequential reads and writes.
On the software front, Dell is including the Dell Precision Performance Optimizer and the Intel Cache Acceleration Software. The former automatically configures and optimizes the workstation for specific applications based on profiles that are reportedly regularly updated. The other bit of software works to optimize systems that use both hard drives and SSDs with the SSDs as a cache for the mechanical storage. The Intel Cache Acceleration Software configures the caching algorithms to favor caching very large files on the solid state storage. It is a different approach to consumer caching strategies, but one that works well with businesses that use these workstations to process large data sets.
The Dell Precision T7610 workstation.
The Dell workstations are aimed at businesses doing scientific analysis, professional engineering, and complex 3D modeling. The T7610 in particular is aimed at the oil and gas industry for use in simulations and modeling as companies search for new oil deposits.
All three systems will be available for purchase worldwide beginning September 12th. Some of the options, such as 512GB of ECC and the NVIDIA Quadro K6000 on the T7610 will not be available until next month, however. The T3610 has a starting price of $1,099 while the T5610 and T7610 have starting prices of $2,729 and $3,059 respectively.
