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:

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.

The price of upgrading, DDR4 starts to appear

DDR4 is starting to arrive at NewEgg and some kits are actually in stock for those who want to be the first on their block to have these new DIMMs and can remortgage their home.  The price of Haswell-E CPUs and motherboards is as of yet unknown but looking over the past few years of Intel's new processors you can assume the flagship processor will be around $999.99 with the feature rich motherboards starting around $200 and quickly raising from there.

32gb.png

Both G.SKILL and Crucial have lead with 32GB kits in DDR4-2133 and DDR4-2400 and as you can see the price for their DIMMs and most likely the competitions will be between $450 to $500.

16gb.png

At the 16GB mark you have more choices with Corsair joining in and a range of speeds that go up to DDR4-2800 as well as your choice of a pair of 8GB DIMMs or four 4GB DIMMs.  Corsair was kind enough to list the timings, the DDR4-2666 @ 15-17-17-35 and the DDR4-2800 @ 16-18-18-36 though you will certainly pay a price for the RAM with the highest frequencies.

8gb.png

For those on a budget it would seem like waiting is your best choice, especially as Amazon is offering a limited selection of the new kits, as there is only a single 8GB kit from Crucial although you can buy two of the single DIMMs without heatspreaders for $110. 

Intel product releases are always dearly priced, the introduction of a new generation of RAM is both exciting and daunting. You will see power reductions, base frequencies that were uncommon in DDR3 and very likely an increase in the ability to overclock these DIMMs but it is going to cost you.  If Haswell-E is in your sights you should start planning on how to afford replacing your CPU, motherboard and RAM at the same time as this is no refresh this is a whole new product line.

Introduction:

A few months back, we took a look at the ADATA Premier Pro SP920 series of SSDs. Those came equipped with the Marvell 88SS9189 controller. Marvell SSD controllers have always done a good job, and they were among the first to support SATA 6Gbit speeds. Crucial was one of the first to adopt the Marvell controller into their SATA SSD products, so it seems fitting that we revisit the 88SS9189 controller in the form of Micron's Crucial M550 Series of SSDs:

Being one of the big manufacturers of SSDs, Micron has some cool production videos. Here's one of their videos covering the production of flash all the way through to the assembly of an SSD. We actually toured one of these plants a few years back. Good stuff:

You still haven't bought a Crucial MX100?

Tagged: ssd, 16nm, crucial, mx100

For a mere $100 you can pick up the 256GB model or for $200 you can double that to 512GB.  That certainly makes the drives attractive but the performance is there as well, often beating its predecessor the MX500 series.  If reliability is a concern the onboard RAIN feature guards against writes to bad flash, there are onboard capacitors to allow writes to finish in the case of power outages and a 3 year warranty.  Check out the full review at The Tech Report if you need a second opinion after Allyn's review.

"The Crucial MX100 is the first solid-state drive to use Micron's 16-nm MLC NAND. It's also one of the most affordable SSDs around, with the 256GB version priced at $109.99 and the 512GB at $224.99. We take a closer look at how the two stack up against a range of competitors, and the results might surprise you."

Introduction, Specifications and Packaging

Introduction:

Back in July of last year, Micron announced production of 16nm flash memory. These were the same 128gbit dies as the previous gen parts, but 16nm means the dies are smaller, meaning more dies from a single wafer, ultimately translating to lower end user cost.

high_res_16nm_nand_die_ssd.jpg

It takes a bit of time for those new flash die shrinks to trickle into mainstream products. Early yields from a given shrink tend to not have competitive endurance on initial production. As production continues, the process gets tweaked, resulting in greater and longer enduring yields.

Crucial Launching MX100 Mainstream SSD Series in June

Subject: Storage | May 22, 2014 - 09:23 AM |
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!

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!

CES 2013: Micron demos DDR4 DIMMs, announces 20nm Crucial M500 SSDs at $0.60/GB

At the Micron/Crucial, we were shown an expansion to their DDR3 memory line, to include lower profile parts:

DSC02818_resize.JPG

These reduced height modules should make for easier installation into HTPC and other small form factor PCs and even 1U Servers.

Next we saw DDR4 running at its native 2133 MHz speed. Here is what the DDR4 DIMM looks like:

DSC02820_resize.JPG

Note the slight bulge at the center of the pin area. This is to make installation easier, as there is a considerable increase in pin count, which would have made installation more difficult if not for that design feature. Note the increased contact density in this pic:

DSC02823_resize.JPG

Last (and most certainly not least), Micron announced their next SSD Series, the M500. This line uses a newer Marvell controller with Micron engineered firmware, driving 20nm IMFT flash:

DSC02835_resize.JPG

All models will employ the enterprise feature of a capacitor bank used to store some reserve power. This helps to minimize any possible data loss should power be interrupted while data is being written:

DSC02837_resize.JPG

Micron told me they are planning a 1TB model, running *MLC* flash (not TLC), and they are shooting for a price point of $600. That's $0.60/GB! If this scales down at the lower capacity points, we should be in for some pretty nice price dips in Solid State Storage for 2013!

Crucial's 16GB Ballistix Tactical has a nice surprise

Tagged: crucial, Ballistix Tactical, 16GB, ddr3-1600

It is a nice change when a company understates the performance of their product instead of barely living up to their promises.  Such is the case with the dual channel Crucal Ballistix Tactical 1600MHz kit, at least the one that Funky Kit benchmarked.  They hit 2133MHz and kept the timings at 9-9-9-24 1T, not bad for DIMMs which are billed for 8-8-8-24 1T@ 1600MHz!  Even better these DIMMs are very low profile, so even on boards with the DIMM slots clustered around the CPU socket you won't be limited in your choice of oversized CPU coolers.  The full review is available here.

FJ_crucial16gb-sticks-overview.jpg

"This has been some fun memory to play with, it's ability to hit clocks 50% higher than stock is impressive. It's ability to hit 2133MHz with 9-9-9 timings at only 1.5v is quite impressive."
