...you get the Samsung PM863 and SM863 lines of enterprise SSDs! These 2.5" SATA units were just announced, and as we suspected after reviewing the new 2TB 850 EVO and Pro, these new models can include even more flash packages, dramatically increasing the flash capacity. Here is a breakdown of the launch pricing and capacities:
SM863 (2-bit MLC VNAND):
- 120GB - $140 ($1.17/GB)
- 240GB - $180 ($0.75/GB)
- 480GB - $330 ($0.69/GB)
- 960GB -
$870 ($0.91/GB) < possible typo$640 ($0.67/GB)
- 1.92TB - $1260 ($0.66/GB)
PM863 (3-bit MLC VNAND):
- 120GB - $125 ($1.04/GB)
- 240GB - $160 ($0.67/GB)
- 480GB - $290 ($0.60/GB)
- 960GB - $550 ($0.57/GB)
- 1.92TB - $1100 ($0.57/GB)
- 3.84TB - $2200 ($0.57/GB)
These are some very competitive prices for enterprise SSDs, and the fact that the TLC version can cram just under 4TB into a 7mm 2.5" form factor is just astounding. The MLC version capacities appear to still follow that of the 850 Pro, minus a bit of available capacity due to higher levels of over-provisioning.
More impressive is the endurance ratings of these SSDs. The SM863 line is rated (varying by capacity) from 770 Terabytes Written (TBW) to an astonishing 12,320 TBW for the 1.92TB model! That's over 12 Petabytes! The PM863 is rated lower as it is TLC based, but is still no slouch as it ranges from 170 to 5,600 TBW for the 3.84TB capacity. The SM863 carries a 5-year warranty, while the PM863 drops that to 3-years.
We've been waiting to see Samsung's 32-layer VNAND appear in enterprise units for some time now, and look forward to testing them just as soon as we can get our hands on them!
Full press blast after the break.

[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
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:
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.

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
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).

Tagged: SM951, Samsung, PCIe SSD, M.2
Samsung's M.2 SM951 PCIe SSD was never originally intended to be sold on its own but thankfully the 128, 256 and 512GB models are showing up on Newegg and other sites and the speeds it can reach are very impressive. The Tech Report tested the 512GB model and saw it beat the Intel 750 Series in IOMeter at a queue depth of one, though the Intel SSD still shows off its prowess at higher queue depths. Their testing showed that the speed of the flash produces enough heat that the drive throttles itself so you should consider rigging an active cooling solution if you do pick up this drive. Check out their full review to see some very impressive numbers and boot times.
"Samsung's SM951 SSD squeezes a quad-lane PCIe Gen3 interface onto a diminutive M.2 form factor. It offers incredible performance under the right conditions, but it also struggles in some scenarios. Our in-depth review explains the drive's strengths, weaknesses, and unique enthusiast appeal."

One hub to rule them all!
Inateck sent along a small group of connectivity devices for us to evaluate. One such item was their HB7003 7 port USB 3.0 hub:
This is a fairly standard powered USB hub with one exception - high speed charging. Thanks to an included 36W power adapter and support for Battery Charging Specification 1.2, the HB7003 can charge devices at up to 1.5 Amps at 5 Volts. This is not to be confused with 'Quick Charging', which uses a newer specification and more unique hardware.
- L/W/H: 6.06" x 1.97" x 0.83"
- Ports: 7
- Speed: USB 3.0 5Gbps (backwards compatible with USB 2.0 and 1.1)
- Windows Vista / OSX 10.8.4 and newer supported without drivers
Densely packed brown box. Exactly how such a product should be packaged.
Power adapter (~6 foot cord), ~4.5 foot USB 3.0 cord, instruction manual, and the hub itself.
Some quick charging tests revealed that the HB7003 had no issue exceeding 1.0 Amp charging rates, but fell slightly short of a full 1.5A charge rate due to the output voltage falling a little below the full 5V. Some voltage droop is common with this sort of device, but it did have some effect. In one example, an iPad Air drew 1.3A (13% short of a full 1.5A). Not a bad charging rate considering, but if you are expecting a fast charge of something like an iPad, its dedicated 2.1A charger is obviously the better way to go.
Performance and Usability:
As you can see above, even though the port layout is on a horizontal plane, Inateck has spaced the ports enough that most devices should be able to sit side by side. Some wider devices may take up an extra port, but with seven to work with, the majority of users should have enough available ports even if one or two devices overlap an adjacent port. In the above configuration, we had no issue saturating the throughput to each connected device. I also stepped up to a Samsung USB T1 which also negotiated at the expected USB 3.0 speeds.
Pricing and Availability
- $34.99 (Amazon)
Inateck is selling it these direct from their Amazon store (link above).
- Clean design 7-port USB 3.0 hub.
- Port spacing sufficient for most devices without interference.
- 1.5A per port charging.
- Low cost.
- 'Wall wart' power adapter may block additional power strip outlets.
At just $35, the Inateck HB7003 is a good quality 7-port USB 3.0 hub. All ports can charge devices at up to 1.5A while connecting them to the host at data rates up to 5 Gbps. The only gripe I had was that the hub was a bit on the light weight side and as a result it easily slid around on the desk when the attached cords were disturbed, but some travelers might see light weight as a bonus. Overall this is a simple, no frills USB 3.0 hub that gets the job done nicely.
You love the dock!
Today we'll take a quick look at the Inateck FD2002 USB 3.0 to dual SATA dock:
This is a UASP capable dock that should provide near full SATA 6Gb/sec throughput to each of two connected SATA SSDs or HDDs. This particular dock has no RAID capability, but exchanges that for an offline cloning / duplication mode. While the FD2002 uses ASMedia silicon to perform these tasks, similar limitations are inherent in competing hardware fron JMicron, which comes with a similar toggle of either RAID or cloning capability. Regardless, Inateck made the logical choice with the FD2002, as hot swap docks are not the best choice for hardware RAID.
The pair of ASMedia chips moving data within the FD2002. The ASM1153E on the left couples the USB 3.0 link to the ASM1091R, which multiplexes to the pair of SATA ports and apparently adds cloning functionality.

Tagged: transporter, NAS, dropbox, connected data
Today Connected Data (makers of Drobo) announced NAS integration with their Transporter 75 and 150 business private cloud storage devices.
The premise of this addition is simple. Businesses can simply point a Transporter 75 or 150 unit at their local NAS device and have that storage accessible via the usual Transporter methods. These work very much like Dropbox, where files can be synced across systems or available from a remote source, except in this case the 'could' is provided by a box located and secured at the business offices.
Transporter devices can also be added to smaller branch offices or other locations. Those remote locations can keep a subset (or all) of the data from the main office, preventing the need to have a full copy of all data synced across each and every system. The Transporter Desktop app can map shared folders and access them straight off of the network. Shares can also be synced with a local copy if the user chooses to do so.
It's good to see Connected Data continue to develop this platform, and we hope to see this NAS integration feature added to the smaller capacity 15 and 30 models as this would help speed adoption and integration for smaller businesses that have started out with all content on a smaller local NAS.
