Plextor is introducing a new SATA SSD option with its 2.5” M8VC and M.2 M8VG solid state drives. The M8V series pairs a Silicon Motion SM2258 controller with Toshiba’s 64-layer 3D TLC NAND (BICS flash) to deliver budget SSDs in 128 GB, 256 GB, and 512 GB capacities. Plextor is using its own Plex Nitro firmware and includes SLC cache, system RAM cache support, Plex Compressor compression, 128-bit ECC and LDPC error correction, and hardware AES encryption. Plextor warranties its M8V series SSDs for three years.

Plextor’s new drives are limited by the SATA 6 Gbps interface and max out at 560 MB/s sequential reads. Sequential writes top out at 400 MB/s for the 128 GB model, 510 MB/s for the 256 GB model, and 520 MB/s for the 512 GB drive. Similarly, 4K random reads and 4K random writes scale up as you add more flash which is shown in the table below. The top-end 512 GB drive hits 82K 4K random read IOPS and 81K 4K random write IOPS. The 256 GB solid state drives are only slightly slower at 81K and 80K respectively. The 128 GB M8V SSDs do not appear to have enough flash channels to keep up with the larger capacity drives though as their performance maxes out at 60K random reads and 70K random writes.

Plextor M8V Series 128 GB 256 GB 512 GB
Sequential Reads 560 MB/s 560 MB/s 560 MB/s
Sequential Writes 400 MB/s 510 MB/s 520 MB/s
4K Random Read IOPS 60K 81K 82K
4K Random Write IOPS 70K 80K 81K
Endurance 70 TBW 140 TBW 280 TBW
DWPD 0.5 0.5 0.5
MTBF (hours) 1.5 Million 1.5 Million 1.5 Million

Plextor rates the M8V series at 0.5 DWPD (drive writes per day) and write endurance of 70 TB for the 128 GB, 140 TB for the 256 GB, and 280 TB for the 512 GB model. Plextor rates them at 1.5 million hours MTBF. These numbers aren’t too bad considering this is TLC flash and they are likely to get more life than the ratings (it’s just not guaranteed).

The SM2258 controller appears to be fairly well established and has also been used by Adata, Mushkin, and others for their budget solid state drives. Plextor did not announced pricing or availability and in searching around online I was not able to find them for sale yet. Its previous S2C series (M7V replacement) SATA drives came in at just under 26 cents/gigabyte using the same SMI 2258 controller but with SK Hynix 16nm planar TLC flash though so I would expect the M8V to come in close to that if not better.

I just wish we could get a SATA 4 standard already to at least get consumer systems up to the 12 Gbps enterprise-oriented SAS can hit. While RAM and GPU shopping may make your wallet cry more than a Steam sale, at least it is a good time to be shopping for storage. What do you think about the influx of budget SSDs? Have you upgraded your family’s PCs to the magical performance of solid state storage yet?

Mushkin is on site at CES where it is launching a slew of new products. On the storage front, Mushkin is showing off three new M.2 2280 form factor NVMe solid state drives aimed at various price points. The Pilot, Pilot-E, and Helix-L M.2 drives all use Silicon Motion controllers and 3D TLC NAND flash memory. Mushkin further advertises them with a three-year warranty and the company's MEDS Reliability Suite which includes technology to enable end-to-end data path protection, LDPC ECC, and global wear leveling algorithms to ensure data integrity and longevity.

At the top end of performance is the Pilot-E M.2 SSD based on SM2262EN controller which offers up eight channels for connecting all the 3D NAND. This 250 GB to 2 TB drive is able to achieve extremely speedy 3.5 GB/s sequential reads and 3.0 GB/s sequential writes along with 370K read IOPS and 300K write IOPS. Essentially, the Pilot-E M.2 should be able to easily max out the PCI-E x4 connection with the right workloads.

Stepping down a bit, the Pilot drive uses an eight channel SM2262 controller. This drive gets close to the Pilot-E in reads, but has much lower sequential write performance. Capacities for this SSD range from 120 GB to 2 TB. Specifically, the Pilot SSD is rated at 3.2 GB/s sequential reads, 1.9 GB/s sequential writes, 370K random read IOPS, and 300K random write IOPS. This drive should be cheaper than the Pilot-E and will be aimed at the consumer space where reads are more important than writes.

Finally, Mushkin's Helix-L is a lower cost SSD that uses a DRAM-less design to reduce cost as well as a cheaper four channel SM2263XT controller. Capacities range from 120 GB to 1TB. This SSD supports Host Memory Buffer architecture which allows it to use system memory as a cache to improve performance. The Helix-L is rated at 2.4 GB/s sequential reads, 1.7 GB/s sequential writes, 280K random read IOPS (140K without HMB) and 250K random write IOPS.

Mushkin has not yet revealed pricing or availability on its new NVMe 1.3 drives. You can read more about the Silicon Motion controllers used here.

ADATA's new entry level SSD is the second to the market which utilizes Micron's 3D NAND and also incorporates the new SM2258G controller from Silicon Motion.  ATTO shows the performance you would expect from a drive in this class, 560MB/s read 512MB/s write for sequential data at 128KB and higher, assuming you do not completely fill the SLC cache.  The SSD Review did not see write performance drop off until they had written 60GB in one shot, the drop is quite dramatic but for most users 60GB writes happen infrequently.  Check out the full review if you are in the market for a value priced SSD.

"The Ultimate SU800, on the other hand, utilizes a newer Silicon Motion controller and is the second SSD in the market utilizing Micron's 3D TLC NAND. This combination of components has us charting into new waters when it comes to evaluating the performance."

Hello, Canadians! Interested in a Relatively Cheap 1TB SSD?

Subject: Storage | March 23, 2016 - 06:16 PM |
Tagged: newegg, Mushkin, silicon motion, micron, ssd

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.

Silicon Motion has updated their popular SM2246EN controller to support MLC 3D NAND from IMFT and SK Hynix:

160105-215942.jpg

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:

160105-215614.jpg

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:

benches.png

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:

160105-215637.jpg

160105-215859.jpg

...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.

FMS 2015: Silicon Motion SM2260 PCIe 3.0 x4 NVMe Controller Spotted

Subject: Storage | August 14, 2015 - 04:44 PM |

We’ve reviewed a few Silicon Motion SSDs in the past (Angelbird | Corsair Force LX | Crucial BX100), and I have always been impressed with their advances in SSD controller technology. Their SM2246EN SATA controller was launched two years ago, and strived to be a very efficient and performant unit. Based on our reviews that turned out to be true, and this allowed Silicon Motion to slide into the void left by SandForce, who repeatedly delayed their newer developments and forced the many companies who were sourcing their parts to look elsewhere.

The many SSDs using Silicon Motion’s SM2246EN controller.

Silicon motion pushed this further with their SM2256, which we first saw at the 2014 Flash Memory Summit and later saw driving SLC/TLC hybrid flash at this past Consumer Electronics Show. While the SM2256 makes its way into more and more products, I was glad to see an important addition to their lineup at this year’s FMS:

DSC04544.jpg

Finally we see Silicon Motion doing a PCIe controller! This is the SM2260, seen here in the M.2 form factor…

DSC04538.jpg

…and here in SATA Express. While the latter will likely not be as popular due to the more limited PCIe lanes present in SATA Express, I’m sure we will see this controller appearing in many PCIe devices very soon. The stated performance figures may be a bit shy of currently comparing SSDs like the Intel SSD 750 and Samsung SM951, but with the recent introduction of Z170 motherboards and RST PCIe RAID, it is now easier to RAID a smaller capacity pair of these devices, increasing the performance of slower units. Further, the point of the SM2260 is likely to get a low cost NVMe PCIe SSD controller into the hands of SSD makers, which can only mean good things for those looking to make the move away from SATA.

You may remember the Silicon Motion SM2256 SSD controller that Al reported on during CES this year, even if you do not you should be interested in a controller which can work with 1x/1y/1z nm TLC NAND from any manufacturer on the market.  The SSD Review managed to get a prototype which uses the new SM2256 controller, Samsung’s 19nm TLC planar NAND flash and a Hynix 440Mhz 256MB DDR3 DRAM chip.  In benchmarking they saw 548MB/s sequential reads and 484MB/s writes, with 4K slowing down to 38MB/s for read and 110MB/s for write.  Check out the rest of the review here as well as keeping your eyes peeled for our first review of the new controller.

"Controllers are the heart and soul of every SSD. Without one, an SSD would be a useless PCB with some components slapped on it. It is responsible for everything from garbage collection and wear leveling to error correction and hardware encryption. In simple terms, all these operations can be quite complicated to implement as well as expensive to develop."

CES 2015: Silicon Motion SM2256 seen in action, capable of hybrid TLC/SLC caching

Subject: Storage, Shows and Expos | January 8, 2015 - 01:17 AM |
Tagged: CES, ces 2015, silicon motion, SM2256, ssd, tlc, slc

We first saw the Silicon Motion SM2256 controller at Flash Memory Summit, but now we've seen it live, in action, and driving several different types of TLC NAND.

DSC06942_resize.JPG

Silicon Motion had this live demo running on a testbed at their suite:

DSC06936_resize.JPG

The performance looked very good considering the 2256 is designed to efficiently push TLC flash, which is slower than MLC. As their representative was explaining that the SM2256 is currently being tested with Samsung, Toshiba, and SK Hynix TLC flash, I noticed the HDTune write trace:

DSC06939_resize.JPG

Those familiar with HDTune and Samsung SSDs with Samsung's TurboWrite cache (from the 840/850 EVO) will recognize the above - the SSD begins writing at SLC speed and after that cache is full, the SSD then drops to writing at TLC speed. I specifically asked about this, as we've only Samsung flash provisioned with an SLC portion of each die, and the answer was that Toshiba and SK Hynix TLC flash also supports such a subdivision. This is good news, as it means increased competition from competing SSDs that can accomplish the same SLC burst writes as the Samsung EVO series.

We heard from a few vendors that will soon be launching SM2256 equipped SSDs this year, and we eagerly await the opportunity to see what they are capable of.

Introduction, Specifications and Packaging

Introduction:

It seems a lot of folks have been incorporating Silicon Motion's SM2246EN controller into their product lines. We first reviewed the Angelbird SSD wrk, but only in a 512GB capacity. We then reviewed a pair of Corsair Force LX's (256GB and 512GB). ADATA has joined the club with their new Premier SP610 product line, and today we are going to take a look at all available capacities of this new model:

DSC05020.JPG

It's fortunate that ADATA was able to sample us a full capacity spread, as this will let us evaluate all shipping SSD capacites that exist for the Silicon Motion SM2246EN controller.
