Patriot is launching into PCI-E based storage with its new Hellfire line of solid state drives. While Patriot is more commonly known for its flash memory (USB drives and SD cards) and RAM DIMMs, it is not new to SSDs. This will be its first line of PCI-E=based SSDs, however. Two drives in the Hellfire series are currently planned for a release later this year and will come in M.2 NVME and PCI-E add-in-card (AIC) versions.
The company is not talking specifics yet, and we will not know full speeds and feeds or pricing for a few months. They did reveal a few scraps of information with the press release though. Both versions of the Hellfire drives (M.2 and AIC) will be powered by a Phison 5007 controller and will use MLC NAND flash. Further, the drives will come in 240GB, 480GB, and 960GB capacities. The drives do differ greatly in performance with the Add-In-Card version having significantly better write and slightly improved read performance. Specifically, the M.2 NVME drive is rated at 2,500 MB/s reads and a mere 600 MB/s writes while the AIC version can hit 3,000 MB/s reads and 2,200 MB/s writes.
Patriot expects the Hellfire SSDs to be available by the end of Q1 2016. I welcome the increased PCI-E SSD competition which should help drive prices down further. Hopefully Patriot will release more details soon!

Silicon Motion has updated their popular SM2246EN controller to support MLC 3D NAND from IMFT and SK Hynix:
The SM2246EN acts as a gateway for third parties to make their own SSDs. Adding support for 3D NAND is good news, as it means we will be able to see third party SSDs launch with 3D flash sourced from Intel, Micron, or SK Hynix. Another cool tidbit is the fact that those demo units in the above photo were equipped and operating with actual 3D NAND from Intel, Micron, and SK Hynix. Yes, this is the first time seeing packaged MLC 3D NAND from a company other than Samsung. Here are some close-ups for those who want to read part numbers:
Another question on non-Samsung 3D NAND is how does its performance stack up against planar (2D) NAND? Silicon Motion had a bit of an answer to that question for us:
Keep in mind those are results from pre-production firmware, but I was happy to see that my prediction of IMFT 3D NAND speeds being effectively equal to their previous 2D flash was correct.
To knock out some other info overheard at our briefing, Silicon Motion will also be making an SM2258, which will be a TLC 3D NAND variant of the SM2256. In addition, we saw the unreleased SM2260:
...which is Silicon Motion's PCIe 3.0 x4 SSD controller. This one is expected to surface towards the middle of 2016, and it is currently in the OEM testing stage.
Lots more storage goodies coming later today, so stay tuned! Full press blast for the updates SM2246EN after the break.

Tagged: transcend, slc, mlc, ssd, flash, SuperMLC
Last year we saw Micron toy with the idea of dynamically flipping flash memory dies between SLC and MLC modes. Ok paper, it sounded like a great idea - get the speed of SLC flash while the SSD is up to 50% full, then start shifting dies over to MLC mode to get the higher capacity. This tech did not exist until the ability to flip dies between modes existed, which was not until shortly before the M600 SSDs were introduced. Realize this is different than other types of mixed mode flash, like that on the Samsung 'EVO' models, which have a small SLC segment present on each TLC die. That static partitioning kept those types of solutions more consistent in performance than the M600 was when we first evaluated its performance.
What if we borrowed the idea of keeping the flash mode static, but just keeping to the faster mode? Transcend has announced it will be doing just that in the coming year. These will be SSDs equipped with MLC flash, but that flash will be configured to operate in SLC mode full time. This will enable ~4x write speeds and higher endurance ~30,000 write cycles compared to ~5-10k P/E cycle figures of the same flash operating in MLC mode. This performance and endurance boost comes at a cost, as these SSDs will consume twice the flash memory for the equivalent MLC model capacity. We predict this type of substitution for standard SLC flash will be a continuing trend since SLC flash production volume is insignificant compared to MLC. This trick gets you most of the way to SLC performance and endurance for (in the current market) less cost/GB of a straight SLC SSD.
Upcoming Transcend models to include SuperMLC technology:
- SSD510K - 2.5”
- MSA510 - mSATA
- HSD510 - half slim
- MTS460 & MTS860 - M.2
Given that we are anticipating a launch of the Samsung 850 EVO very shortly, it is a good time to back fill on the complete performance picture of the 850 Pro series. We have done several full capacity roundups of various SSD models over the past months, and the common theme with all of them is that as the die count is reduced in lower capacity models, so is the parallelism that can be achieved. This effect varies based on what type of flash memory die is used, but the end result is mostly an apparent reduction in write performance. Fueling this issue is the increase in flash memory die capacity over time.
There are two different ways to counteract the effects of write speed reductions caused by larger capacity / fewer dies:
- Reduce die capacity.
- Increase write performance per die.
Recently there has been a trend towards *lower* capacity dies. Micron makes their 16nm flash in both 128Gbit and 64Gbit. Shifting back towards the 64Gbit dies in lower capacity SSD models helps them keep the die count up, increasing overall parallelism, and therefore keeping write speeds and random IO performance relatively high.

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!

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.
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.

Tagged: SM2246EN, S3C, mlc, Apotop
The Apotop S3C SSD uses the same controller as the Angelbird drive Al reviewed recently. It uses synchronous MLC NAND with the 4 channel present on the Silicon Motion controller and is able to provide more than the specified 490 MB/s read and 275 MB/s write in some benchmarks. It can often read faster than the wrk SSD but the writes cannot always keep up though it is not something likely to be noticeable in real usage scenarios. The MSRP is very attractive with the 512GB model expected to be released at $200. Silicon Motion is likely to start appearing in a lot more SSDs in the near future with this mix of price and performance. Read the full review at Kitguru.
"The new Apotop S3C SSD features the Silicon Motion 2246EN controller which we first reviewed in the Angelbird 512GB wrk SSD back in August this year. The controller impressed us, so we have already high hopes for the Apotop S3C."
