SK Hynix has revealed its new enterprise solid state drives based on 72-layer 512 Gb 3D TLC NAND flash dies paired with the company's own in-house controller and firmware. The SK Hynix eSSDs are available in a traditional SAS/SATA interfacing product with capacities up to 4TB and a PCI-E variant that comes in 'above 1TB." Both drive types are reportedly being sampled to datacenter customers in the US.
SK Hynix has managed to double the capacity and improve the read latency of its new 512 Gb 72-layer NAND flash over its previous 256 Gb 72-layer flash which debuted last year. The eSSD product reportedly hits sequential read and write speeds of 560 MB/s and 515 MB/s respectively. Interestingly, while random read IOPS hit 98,000, random write performance is significantly lower at 32,000 IOPS. SK Hynix did not go into details, but I suspect this has to do with the tuning they did to improve read latency and the nature of the 72-layer stacked TLC flash.
Moving up to the PCI-E interfacing eSSD, customers can expect greater than 1TB capacities (SK Hynix did not specify the maximum capacity they will offer) with sequential reads hitting up to 2,700 MB/s and sequential writes hitting 1,100 MB/s. The random performance is similar to the above eSSD with write performance being much lower than read performance at 230K read IOPS and 35K write IOPS maximum. The greatly limited write performance may be the result of the drive not having enough flash channels or the flash itself not being fast enough at writes which was a tradeoff SK Hynix had to make to hit the capacity targets with larger capacity 512 Gb (64 GB) dies.
Unfortunately, SK Hynix has not yet provided further details on its new eSSDs or the 3D-V4 TLC NAND it is using in the new drives. SK Hynix continuing to push into the enterprise storage market with its own SSDs is an interesting play that should encourage them push for advancements and production efficiencies to advance NAND flash technology.

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|
|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?

In addition to the PCI-E based solid state drives it showed off at CES, Mushkin is adding two new SATA-based SSDs to its Triactor series. The new Triactor 3DL and Triactor 3DX are M.2 and 2.5" form factor SSDs respectively that are available in 120 GB, 250 GB, 500 GB, and 1 TB capacities and utilize 3D TLC NAND flash memory and SMI controllers. Both drives come with M.E.D.S. wear leveling and data protection algorithms and three-year warranties.
The Triactor 3DL is a M.2 2280 form factor SSD that uses a SMI SM2258XT controller with a SATA 3.1 6 Gbps interface. The SM2258XT is a four-channel controller that lacks a DRAM cache. The Triactor 3DL is rated at up to 550 MB/s sequential reads, 505 MB/s sequential writes, 73,000 random 4k read IOPS and 80,000 random 4k write IOPS. Its data protection features include LDPC ECC and algorithms for data shaping, StaticDataRefresh, and wear leveling. While not as impressive as its NVMe M.2 counterparts, it should be a good bit cheaper and compatible with more PCs especially as an upgrade path for older notebooks.
On the other hand, the Triactor 3DX is a more traditional SATA drive that comes in a 2.5" form factor (7mm thick). In this case the 3D TLC NAND flash is paired with a SMI SM2258 controller which is similar to the one above except that it can utilize a DRAM cache and supports AES encryption. The Triactor 3DX is rated at 565 MB/s sequential reads, 530 MB/s sequential writes, 100,000 random 4k read IOPs, and 91,000 random 4k write IOPS. It seems that the cache is helping performance a bit, and the drive is starting to bump up against the real-world limits of the SATA 6 Gbps interface. Since it is of the thinner 7mm type, it will be compatible with most notebooks and desktops.
The new Triactor drives are cheaper options that come in M.2 as well as traditional SATA drives. Mushkin is not talking pricing or availability just yet.

Crucial showed off the upcoming M.2 variant of its MX500 product, available in capacities up to 1TB. They also announced (press release after the break) that the MX500 will be available from 250GB up to 2TB capacities.
Here is Crucial's product tour video for the MX500:
We previously tested the 1TB MX500, and Crucial passed along a 500GB model that I was able to spot check to ensure there was no performance fall-off at the smaller capacities of this line:
Looks good so far, and nearly identical to the 1TB capacity across our entire test suite. We did also speak with Crucial reps (Jon and Jon) about the TRIM speed issues noted in our previous review. They are looking into replicating our testing and may be pushing out a firmware to help improve this metric moving forward.
We also saw some sweet looking new RGB Ballistix memory, due out shortly. More to follow there! Crucial's MX500 CES announcement appears after the break.

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.

We were extremely impressed with the Micron 9100 Enterprise SSDs. They are still the fastest NAND flash SSDs we've tested to date, but they were built on planar NAND, and we know everyone is replacing their flat flash with more cost efficient 3D NAND. Same goes for the 9200:
Highlights for the new models are IMFT 3D NAND running in TLC mode and a new controller capable of PCIe 3.0 x8 (HHHL form factor only - U.2 is only a x4 interface). Here are the detailed specs:
Improvements for the x4 models are marginal upgrades over the 9100, but the x8 variants bump up the maximum performance to 900,000 IOPS and 5.5GB/s! These should be shipping by the end of the month, and we will review them as they come in.

Last June Al took a look at the Crucial MX300 750GB and its ability to switch its cache dynamically from TLC to SLC, helping Crucial improve how they implemented this feature along the way. It proved to be a great value for the money; not the best performing drive but among the least expensive on the market. Crucial has since expanded the lineup and Hardware Canucks took a look at the 2TB model. This model has more than just a larger pool of NAND, the RAM cache has been doubled up to 1GB and the dynamic cache has more space to work in as well. Take a look at this economy sized drive in their full review.
"Crucial's newest MX300 series continues to roll on with a new 2TB version. This SSD may be one of the best when it comes to performance, price and capacity all combined into one package."

Introduction, Specifications and Packaging
Micron paper launched their 5100 Series Enterprise SATA SSD lineup early last month. The new line promised many sought after features for such a part, namely high performance, high-performance consistency, high capacities, and relatively low cost/GB (thanks to IMFT 3D NAND which is now well into volume production since launching nearly two years ago). The highs and lows I just rattled off are not only good for enterprise, they are good for general consumers as well. Enterprises deal in large SSD orders, which translates to increased production and ultimately a reduction in the production cost of the raw NAND that also goes into client SSDs and other storage devices.
The 5100 Series comes in three tiers and multiple capacities per tier (with even more launching over the next few months). Micron sampled us a 2TB 'ECO' model and a 1TB 'MAX'. The former is optimized more for read intensive workloads, while the latter is designed to take a continuous random write beating.
I'll be trying out some new QoS tests in this review, with plans to expand out with comparisons in future pieces. This review will stand as a detailed performance verification of these two parts - something we are uniquely equipped to accomplish.

DRAMeXchange is predicting a price hike in NAND chips over the coming year thanks to a supply decline combined with an impressive rise in demand. The supply decline is a direct result of the industry's switch in preference to 3D NAND, which requires manufacturers to retool their existing lines. While retooling from the production of 2D to 3D NAND, the line can produce neither and as all available lines were currently at or near full volume production, we are seeing a decline in the amount of available flash chips. Even once lines are retooled, only Samsung has seen an increase in their production volumes, a situation which will hopefully change in the coming year. With demand on the rise as more and more users switch to SSDs and the amount of storage on cellphones increasing in each new model we can only expect to see prices rise. DigiTimes reports a predicted 10% rise in average SSD prices in Q1 of 2017, with prices of eMMC and UFS storage jumping even more.
"From the supply side, the industry-wide transition to 3D-NAND is now moving at full speed," said Sean Yang, research director of DRAMeXchange. "However, most suppliers with the exception of Samsung have not improve their yield rates for the technology as quickly as they would like."

Adata's Ultimate SU800 512GB SSD is somewhat of a mixed bag, at $0.27/GB it is not exactly inexpensive nor does it take advantage of some of the SM2258 controllers advanced features, on the other hand it does use Micron's 3D NAND, offer a dynamic SLC cache and is overprovisioned by 64GB. The Tech Report put this SATA SSD to the test in a barrage of benchmarks to see how its performance compared to other SSDs, both SATA and PCIe. Check out their results right here.
"Adata's first 3D NAND SSD, the Ultimate SU800, uses the same Micron flash memory that company deployed in its appealing Crucial MX300. We tested and dissected the SU800 to see whether it lives up to its Ultimate billing."
