Introduction, Specifications and Packaging
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:
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.
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).

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.
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.
An M.2 NVMe PCIe device placed on top of a U.2 NVMe PCIe device.
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:
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:
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.

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'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.

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

When you pick up a Kingston HyperX Savage SSD you have a choice of the barebones model at $122 for the 240GB model or you can pay an extra $25 for the upgrade kit which contains 2.5mm z-height adapter, a SATA 6Gb/s cable, a 2.5" to 3.5" adapter plate, Acronis True Image HD imaging software, a micro-screwdriver set, and a USB 3.0 enclosure with USB 3.0 cable. That upgrade kit is perfect for those looking for an easy way to move their entire OS to the new SSD with a minimum of fuss. Inside the drive is the Phison PS3110 controller with a 256MB DDR3-1600 cache and Toshiba's 19nm Toggle Mode NAND. Hardware Canucks put the drive to the test and it shows huge improvements from the first generation, enough to put it in competition with offerings from OCZ, Intel and Crucial. This demonstrates a faster evolution that competitors products but it does unfortunately come at a price that is a bit high compared to those competitors offerings.
"The affordable Kingston HyperX Savage is one of the first SSDs to use the new Phison PS3110 controller and the end results are extremely impressive to say the least."

For those of you following the Samsung 840 EVO saga, last week we saw the release of Magician 4.6. Samsung was initially throttling downloads and firmware update rates, but those limits appear to have been lifted as of this morning. Another thing we noticed this morning was the inclusion of the standalone ISO updater for those who are otherwise unable to run the Magician software (i.e. Mac users):
For those on laptops or other devices with no optical drive, I've confirmed the ISO can be used via USB if placed there with a tool such as Rufus.
Note to Linux users:
There was an early report of complications from a user who was running a full disk fstrim during boot, where that operation was causing errors (corrected once that operation was disabled). It should be noted that full disk TRIM operations are redundant so long as the OS is issuing TRIM on-the-fly during regular file moves / deletions. This may be an issue with queued TRIM handling of the new 840 EVO firmware. If not reproduced / corrected by Samsung, the Linux devs may be able to add this firmware revision to the queued TRIM blacklist to possibly fix the problem on their end.
Note to mSATA 840 EVO users:
It appears the update does not currently apply to these. I've asked Samsung about this.

For those who watched last night's podcast live, I predicted that Samsung would be posting their 840 EVO Firmware and new Magician 4.6 software 'soon'. Turns out that 'soon' was actually this morning, but there's a catch - Samsung decided to limit the daily downloads:
If you went to the Samsung SSD Download Page and got the above error, don't fret, there are a few mirrors out there:
I downloaded from these three sources and at the time of this posting can confirm all three are identical to the Magician 4.6 download available from Samsung.
Once installed, you *should* be able to use Magician to update the firmware on your 840 EVO and (hopefully) see its performance come back to where it should be. There have been some reports of users unable to update, but that appears to be Samsung's servers being hammered and Magician's default / timeout is to report that you are on the latest firmware. Restarting Magician may force it to re-check and get the update.
Linux and Mac users are not yet able to update as the ISO updater has not been released for the new firmware. Those capable can update their Linux or Mac 840 EVOs connected as a secondary drive under Windows with Magician 4.6 installed. Also, if you're running Linux and happen use fstrim during boot, read this post prior to updating.
