[H]ard|OCP has just posted a roundup of four affordable SATA SSDs to show which would be the best one to pick up as the majority of users are not able to afford an NVME PCIe SSD.  The drives are all within $50 above or below $200, with the 850 PRO having the highest cost per gigabyte and the EVO the least.  They test content creation and moving large files as well as synthetic benchmarks to come out with a ranking of the four drives which you can refer to if you will be shopping for storage in the near future.  In comparison they use the G.SKILL Phoenix Blade to show off what the new technology can do, for those that can afford it.

"Despite the performance benefits, PCIe SSDs remain an expensive niche market. That means that most of us are not going to be loading up a high end system with PCIe SSDs. Most of us mere mortals will be using SATA SSDs. We tested some of the best SATA drives with enthusiast-friendly price tags."

Introduction, Specifications and Packaging

Introduction:

Since their acquisition by Toshiba in early 2014, OCZ has gradually transitioned their line of SSD products to include parts provided by their parent company. Existing products were switched over to Toshiba flash memory, and that transition went fairly smoothly, save the recent launch of their Vector 180 (which had a couple of issues noted in our review). After that release, we waited for the next release from OCZ, hoping for something fresh, and that appears to have just happened:

OCZ sent us a round of samples for their new OCZ Trion 100 SSD. This SSD was first teased at Computex 2015. This new model would not only use Toshiba sourced flash memory, it would also displace the OCZ / Indilinx Barefoot controller with Toshiba's own. Then named 'Alishan', this is now officially called the 'Toshiba Controller TC58'. As we found out during Computex, this controller employs Toshiba's proprietary Quadruple Swing-By Code (QSBC) error correction technology:

QSBC.png

Error correction tech gets very wordy, windy, and technical and does so very quickly, so I'll do my best to simplify things. Error correction is basically some information interleaved within the data stored on a given medium. Pretty much everything uses it in some form or another. Some Those 700MB CD-R's you used to burn could physically hold over 1GB of data, but all of that extra 'unavailable' space was error correction necessary to deal with the possible scratches and dust over time. Hard drives do the same sort of thing, with recent changes to how the data is interleaved. Early flash memory employed the same sort of simple error correction techniques initially, but advances in understanding of flash memory error modes have led to advances in flash-specific error correction techniques. More advanced algorithms require more advanced math that may not easily lend itself to hardware acceleration. Referencing the above graphic, BCH is simple to perform when needed, while LDPC is known to be more CPU (read SSD controller CPU) intensive. Toshiba's proprietary QSB tech claims to be 8x more capable of correcting errors, but what don't know what, if any, performance penalty exists on account of it.

We will revisit this topic a bit later in the review, but for now lets focus on the other things we know about the Trion 100. The easiest way to explain it is this is essentially Toshiba's answer to the Samsung EVO series of SSDs. This Toshiba flash is configured in a similar fashion, meaning the bulk of it operates in TLC mode, while a portion is segmented off and operates as a faster SLC-mode cache. Writes first go to the SLC area and are purged to TLC in the background during idle time. Continuous writes exceeding the SLC cache size will drop to the write speed of the TLC flash.

Is your game library getting huge? Maybe a 2TB SSD is the answer

Subject: Storage | July 6, 2015 - 03:28 PM |
Tagged: ssd, Samsung, 850 PRO, 850 EVO, 2TB

Samsung is extending their 850 EVO and Pro lineups to include 2TB versions of the popular SSDs thanks to the use of 3D-VNAND; three bit memory on the EVO and two bit on the Pro.  They are rated at the same speeds as their 500GB and above counterparts and The SSD Review had a chance to test that. Interestingly they did indeed find performance differences between the 1TB and 2TB model of the same design, which you can check out in the full review.  Their results were not quite the same as Al's review which was just posted, you should compare the two reviews as well as the systems used for theories on why that is.  You can expect to pay ~$1000 for the 850 Pro 2TB and ~$800 for the 850 EVO 2TB.

"If you look back over the past several years, there have always been three constants that needed to be addressed in order for SSDs to become a viable consumer solution to storage; value, reliability and capacity. One of our first SSD reviews was on an MTron 32GB SSD with a whopping price tag of more than $1500…and they sold!"

Introduction, Specifications and Packaging

Introduction:

Where are all the 2TB SSDs? It's a question we've been hearing since they started to go mainstream seven years ago. While we have seen a few come along on the enterprise side as far back as 2011, those were prohibitively large, expensive, and out of reach of most consumers. Part of the problem initially was one of packaging. Flash dies simply were not of sufficient data capacity (and could not be stacked in sufficient quantities) as to reach 2TB in a consumer friendly form factor. We have been getting close lately, with many consumer focused 2.5" SATA products reaching 1TB, but things stagnated there for a bit. Samsung launched their 850 EVO and Pro in capacities up to 1TB, with plenty of additional space inside the 2.5" housing, so it stood to reason that the packaging limit was no longer an issue, so why did they keep waiting?

The first answer is one of market demand. When SSDs were pushing $1/GB, the thought of a 2TB SSD was great right up to the point where you did the math and realized it would cost more than a typical enthusiast-grade PC. That was just a tough pill to swallow, and market projections showed it would take more work to produce and market the additional SKU than it would make back in profits.

The second answer is one of horsepower. No, this isn't so much a car analogy as it is simple physics. 1TB SSDs had previously been pushing the limits of controller capabilities of flash and RAM addressing, as well as handling Flash Translation Layer lookups as well as garbage collection and other duties. This means that doubling a given model SSD capacity is not as simple as doubling the amount of flash attached to the controller - that controller must be able to effectively handle twice the load.

With all of that said, it looks like we can finally stop asking for those 2TB consumer SSDs, because Samsung has decided to be the first to push into this space:

150705-191310.jpg

Today we will take a look at the freshly launched 2TB version of the Samsung 850 EVO and 850 Pro. We will put these through the same tests performed on the smaller capacity models. Our hope is to verify that the necessary changes Samsung made to the controller are sufficient to keep performance scaling or at least on-par with the 1TB and smaller models of the same product lines.

Introduction, Specifications, and Packaging

Lexar is Micron’s brand covering SD Cards, microSD Cards, USB flash drives, and card readers. Their card readers are known for being able to push high in the various speed grades, typically allowing transfers (for capable SD cards) much faster than what a typical built-in laptop or PC SD card reader is capable of. Today we will take a look at the Lexar ‘Professional Workflow’ line of flash memory connectivity options from Lexar.

150121-164114.jpg

This is essentially a four-bay hub device that can accept various card readers or other types of devices (a USB flash storage device as opposed to just a reader, for example). The available readers range from SD to CF to Professional Grade CFast cards capable of over 500 MB/sec.

We will be looking at the following items today:

  • Professional Workflow HR2
    • Four-bay Thunderbolt™ 2/USB 3.0 reader and storage drive hub
  • Professional Workflow UR1
    • Three-slot microSDHC™/microSDXC™ UHS-I USB 3.0 reader
  • Professional Workflow SR1
    • SDHC™/SDXC™ UHS-I USB 3.0 reader
  • Professional Workflow CFR1
    • CompactFlash® USB 3.0 reader
  • Professional Workflow DD256
    • 256GB USB 3.0 Storage Drive

Note that since we were sampled these items, Lexar has begun shipping a newer version of the SR1. The SR2 is a SDHC™/SDXC™ UHS-II USB 3.0 reader. Since we had no UHS-II SD cards available to test, this difference would not impact any of our testing speed results. There is also an HR1 model which has only USB 3.0 support and no Thunderbolt, coming in at a significantly lower cost when compared with the HR2 (more on that later).

The Connector Formerly Known as SFF-8639 - Now Called U.2

Subject: Storage | June 8, 2015 - 04:04 PM |
Tagged: U.2, ssd, SFF-8639, pcie, NVMe, Intel, computex 2015, computex

Intel has announced that the SSD Form Factor Working Group has finally come up with a name to replace the long winded SFF-8639 label currently applied to 2.5" devices that connect via PCIe.

u2-nvme-ssd.jpg

As Hardwarezone peeked in the above photo, the SFF-8639 connector will now be called U.2 (spoken 'U dot 2'). This appropriately corresponds with the M.2 connector currently used in portable and small form factor devices today, just with a new letter before the dot.

Just as how the M.2 connector can carry SATA and PCIe signaling, the U.2 connector is an extension of the SATA / SAS standard connectors:

Demartek_SFF-8639.png

Not only are there an additional 7 pins between the repurposed SATA data and power pins, there are an additional 40 pins on the back side. These can carry up to PCIe 3.0 x4 to the connected device. Here is what those pins look like on a connector itself:

Further details about the SFF-8639 / U.2 connector can be seen in the below slide, taken from the P3700 press briefing:

IntelP3700-SFF8639_w_600.png

With throughputs of up to 4 GB/sec and the ability to employ the new low latency NVMe protocol, the U.2 and M.2 standards are expected to quickly overtake the need for SATA Express. An additional look at the U.2 standard (then called SFF-8639), as well as a means of adapting from M.2 to U.2, can be found in our Intel SSD 750 Review.

Computex 2015: Micron Announces 16nm TLC For Consumer SSDs

Subject: Storage, Shows and Expos | June 2, 2015 - 11:47 PM |
Tagged: tlc, ssd, micron, flash, computex 2015, computex, 16nm

Chugging right along that TechInsights Flash Roadmap we saw last year, Micron has announced the TLC extension to their 16nm flash memory process node.

Micron Roadmap.png

While 16nm TLC was initially promised Q4 of 2014, I believe Micron distracted themselves a little with their dabbles into Dynamic Write Acceleration technology. No doubt wanting to offer ever more cost effective SSDs to their portfolio, the new TLC 16nm flash will take up less die space for the same capacity, meaning more dies per 300mm wafer, ultimately translating to lower cost/GB of consumer SSDs.

micron_128gb_16nm_nand_flash.jpg

Micron's 16nm (MLC) flash

The Crucial MX200 and BX100 SSDs have already been undercutting the competition in cost/GB, so the possibility of even lower cost SSDs is a more than welcome idea - just so long as they can keep the reliability of these parts high enough. IMFT has a very solid track record in this regard, so I don't suspect any surprises in that regard.

Full press blast appears after the break.

Computex 2015: OCZ Trion and Z-Drive 6000, 6300 SSDs Sighted

OCZ is showing off some new goodies at Computex 2015 in the form of a completely new SSD model – the Trion:

Trion Pic.jpg

The Trion is based on an in-house Toshiba ‘Alishan’ controller – the first internal design from that company. Since it is sourced from within Toshiba, the new SSD controller is to be tuned for consumer workloads and should employ lower power states than prior OCZ / Indilinx SSD controllers, as well as Toshiba’s own proprietary QSBC (Quadruple Swing-By Code) error correction technology, which should squeeze a bit more usable life out of the A19nm TLC flash. This is what QSBC looks like compared to competing BCH and LDPC technologies:

QSBC.png

We suspect Toshiba dialed back the algorithm a bit for client usage, but it should still be far superior to BCH. We don’t have many more details as the Trion has not yet been officially launched, but we do have this shot of a round of benchmark results from a pre-production 960GB model:

Trion-2.JPG

From what we can see, it appears to be a good performer (by modern SATA 6Gb/sec SSD standards), but we naturally can't tell anything for sure until we get samples in for local testing, as we have no idea of the state of preconditioning of the Trion in those tests.

Also on display were the recently launched Z-Drive 6000 and 6300 Series parts:

ZDrive6000.jpg

ZDrive 6300 pic1.jpg

These are OCZ’s enterprise-grade NVMe devices, available in 800GB, 1.6TB, and 3.2TB. The 6000 series is a 2.5” 15mm SFF-8639 device aimed at lighter workloads with a rating of 1 Drive Write Per Day (DWPD) over a 5-year period, while the 6300 series brings that figure up to 3 DWPD and offers an HHHL PCIe card as an optional form factor. The higher writes per day are facilitated by the move to A19nm eMLC flash.

We’ll be keeping a close eye on these new developments from OCZ and we are eager to get these in the shop for some thorough testing!

Press blast for the Trion and Z-Drive 6300 Series after the break!

For owners of Z97 or X99 boards with updated UEFIs or a rare SFF-8643 connector for the 2.5" version, booting from NVMe is possible, for the rest the Intel SSD 750 will have to be a storage drive.   Al recently looked at this more than impressive PCIe SSD and now [H]ard|OCP has had a bash at it.  The review is certainly worth checking out as some of their tests, especially the real world ones, differ from the benchmarks that Al used.  This will give you more information about how the new SSD will handle your workloads, research worth it if you are thinking of spending $1055 for the 1.2TB model.

"Intel is set to be the catalyst for a long-awaited leap forward in storage technology with the new SSD 750 bringing NVMe storage to client PCs for the first time, and turning the high end SSD space upside-down. We are expecting blinding IOPs and we dig in to find out what it can mean to the hardware enthusiast."

Introduction, Specifications and Packaging

Introduction:

Back in November of last year, we tested the Corsair Neutron XT, which was the first product to feature the Phison PS3110-S10 controller. First spotted at Flash Memory Summit, the S10 sports the following features:

  • Quad-core controller - Quad-core CPU dedicates three cores just to managing flash and maintaining performance
  • Maximum throughput and I/O - Offers speeds of up to 560 MB/s read and 540 MB/s write and 100K IOPs on read and 90 IOPs on write, saturating the SATA 6Gbps bus
  • End-to-end Data Path Protection - Enterprise level CRC/ECC corrects internal soft errors as well as detecting and correcting any errors that may arise between the DRAM, controller, and flash
  • SmartECC™ - Reconstructs defective/faulty pages when regular ECC fails
  • SmartRefresh™ - Monitors block ECC health status and refreshes blocks periodically to improve data retention
  • SmartFlush™ - Minimizes time data spends in cache to ensure data retention in the event of power loss
  • Advanced wear-leveling and garbage collection

Corsair was Phison's launch partner, but as that was a while ago, we now have two additional SSD models launching with the S10 at their core:

150504-141008.jpg

To the left is the Kingston HyperX Savage. To the right is the Patriot Ignite. They differ in flash memory types used, available capacities, and the stated performance specs vary slightly among them. Today we'll compare them against the Neutron XT as well as a selecton of other SATA SSDs.
